local waste disposal regulations, details of which can be obtained from your
local authority or the dealer you purchased the product from.
The operation of medical appliances may be affected. Be aware of the technical
conditions in your particular environment, e.g. doctor's surgery.
Do not hold the rear of the handset to your ear when it is ringing or when the
handsfree function is activated. Otherwise you risk serious and permanent dam-
age to your hearing.
The handset may cause an unpleasant humming noise in hearing aids.
Do not install the base station or charging cradle in bathrooms or shower rooms.
The handset, base station and charging cradle are not splashproof (page 163).
Do not use the phone in environments with a potential explosion hazard,
e.g. paint shops.

Gigaset C470 IP/C475 IP – More than justa telephone
Gigaset C470-C475 IP / GBR / A31008-M1916-L101-1-7619 / starting.fm / 7.2.08
Version 2.1, 08.01.2007
Gigaset C470 IP/C475 IP – More than just a telephone
Your phone lets you make calls both via the fixed line network and (cost effectively) via the
Internet (VoIP) without using a PC. – Your phone can do much more besides:
uPress a button each time you make a call to indicate whether you want to call via the
fixed line network or the Internet (page 30).
uRegister up to six handsets on your base station. With your base station, you can simul-
taneously conduct two calls via VoIP and one call via the fixed line network.
uMultiline: Create up to six VoIP accounts with different VoIP providers. Together with
your fixed line number and the Gigaset.net number, your phone can then be reached
via up to eight different phone numbers.
uAssign each handset its own VoIP number as a send and receive number. If a member
of your family is called on their VoIP number, only their handset will ring (page 144).
uYou can also use the VoIP accounts with different providers for cost control purposes.
When dialling, specify the VoIP connection/the VoIP account you want to use for its
lower rates (page 31).
uSetting dialling plans for phone numbers or area codes enables you to automate the
selection of the most cost-effective VoIP connection (page 149).
uDetermine which of your phone numbers should be answered by the Gigaset C475 IP
answer machine (page 145).
uUse Gigaset.net for VoIP calls. Connect your phone to the mains power supply and the
Internet, and enjoy free phone calls on Gigaset.net – without making any further set-
tings (page 40).
uConfigure the phone connection for VoIP without a PC. Your phone's connection assist-
ant downloads general data about your VoIP provider from the Internet and guides you
through entering your personal data (VoIP/SIP account). This makes it easy for you to
start using VoIP (page 19).
uIf necessary, make any further VoIP settings on a PC. The phone features a Web interface
(Web configurator) that can be accessed via your PC's Web browser (page 124).
uUse instant messaging on your handset. Go online and see which of your messenger
contacts (buddies) are also online. Exchange SMS messages with your buddies or simply
give them a call (page 84). A free messenger account is already set up for you on the
Gigaset.net Jabber server (page 153).
uLet your phone tell you, without requiring a PC, about new e-mail messages in your
mailbox (page 81). Use your handset to delete old e-mail messages from your mailbox.
uMake sure your phone is always up-to-date. Keep yourself informed about firmware
updates on the Internet and download them onto your phone (page 116).
uYou can reduce the transmission power by activating eco mode (page 24).
Enjoy using your new phone!
Your Gigaset C470 IP/C475 IP has a protected operating system that offers increased security
against viruses from the Internet.

VoIP – making calls via the Internet
Gigaset C470-C475 IP / GBR / A31008-M1916-L101-1-7619 / starting.fm / 7.2.08
Version 2.1, 08.01.2007
VoIP – making calls via the Internet
With VoIP (Voice over Internet Protocol), your calls are not made via a fixed connection as
in the telephone network, but rather they are transmitted via the Internet in the form of
data packets.
You can take advantage of all the benefits of VoIP with your phone:
uYou can make cost-effective calls in high voice quality with callers on the Internet, the
fixed line network or the mobile phone network.
uVoIP providers will give you personal numbers, with which you can be reached from the
Internet, the fixed line network and any mobile phone network.
To be able to use VoIP, you need the following:
uA broadband Internet connection (e.g. DSL) with flat rate (recommended) or volume-
based price.
uInternet access, i.e. you need a router that will connect your phone to the Internet.
You can find a list of recommended routers on the Internet at:
www.siemens.com/gigasetcustomercare
Once you are on the Web page, open the FAQ page and select "Gigaset C470 IP" or
"Gigaset C475 IP". Search for "Router", for example.
uAccess to the services of a VoIP provider. You can open up to six accounts with different
VoIP providers.

uOnly use the mains adapter and phone cord supplied.
uIf you buy a replacement phone cord from a retailer, pay attention to the wiring of the
phone jack.
You can now use your phone to make calls via the fixed line network and can be reached
on your fixed line number.
The answer machine on the Gigaset C475 IP has a standard announcementwhen recording
mode is active (page 71).
3. Connect the base station with the router (Internet)
For Internet access you need a router connected to the Internet via a modem (this may be
integrated in the router).
1. Connect one Ethernet cable plug into the LAN socket at the side of the base station.
2. Then insert the second Ethernet cable plug into a LAN socket on the router.

Version 2.1, 08.01.2007
As soon as the cable connecting the phone and router is plugged in, the key lights up on
the front of the base station (paging key).
You can now establish VoIP connections within Gigaset.net (page 40).
Making settings for VoIP telephony
Before you can use the Internet (VoIP) to phone any other numbers on the Internet, the
fixed line network or the mobile phone network, you need the services of a VoIP provider
who supports the VoIP SIP standard.
Precondition: You have registered with such a VoIP provider (e.g. via your PC) and set up
at least one VoIP account.
The following phone settings are necessary in order for you to use VoIP. You can obtain the
following information from your VoIP provider:
uYour user name with the VoIP provider, if this is required by the VoIP provider
uYour registration name
uYour password with the VoIP provider
uVoIP provider general settings
The connection assistant will help you with the settings.
Automatic configuration:
If your provider supports "automatic configuration", you will receive an "auto configuration code"
from your provider instead of an authentication name and password.
You will need to set the VoIP configuration with the auto-configuration code via the Web configurator
on the base station (see page 124 "Connect the PC with the telephone's Web configurator" and
page 133 "Configuring the VoIP connection")

Version 2.1, 08.01.2007
Starting the connection assistant
Precondition: The base station is connected to the mains power supply and a router. Your
router is connected to the Internet (page 17).
Tip: Leave VoIP activated as the default connection for your telephone (default setting,
page 116). The telephone then attempts to establish a connection directly to your VoIP pro-
vider's server after the connection assistant is closed. If incorrect/incomplete information
means that the connection cannot be established, messages will be displayed (page 22).
As soon as the handset battery is sufficiently charged, the message key f on the handset
will flash (approx. 20 minutes after you have put the handset in the charging cradle). Press
the message key f to start the connection assistant.
You will see the following display:
§Yes§ Press the display key to start the connection assistant.
~Enter the system PIN (default is 0000) and press §OK§.
If you press §No§, the procedure that follows is described under "Entering your name in the
Gigaset.net directory" on page 21.
Please note:
Your phone is preconfigured for dynamic assignment of the IP address. In order for your router to "rec-
ognise" the phone, dynamic IP address assignment must also be activated on the router, i.e. the
router's DHCP server is activated. Turn to page 120 to find out how to assign your phone a static IP
address if necessary.
Please note:
The connection assistant will also start automatically if you try to establish a connection via the Inter-
net before you have made the necessary settings.
You can also call up the connection assistant at any time via the menu (page 118).

Enter the VoIP user data for the first VoIP account. Your VoIP provider will supply you with
this data.
Username:
Enter the user name and press §OK§ if this is required by your provider.
Authent. Name:
Enter the registration name and press §OK§.
Authent. Password:
Enter password and press §OK§.
If the data for your VoIP provider is not available for download, press the ” display key twice. You
can then carry out the following steps with the connection assistant.
You must then make the settings needed for the VoIP provider using the Web configurator
(page 133). Your VoIP provider will supply you with this data.
You can enter five additional VoIP accounts (VoIP phone numbers) via the Web configurator at a later
stage (page 132). Your phone (together with your fixed line number) can then be reached on up to
seven different phone numbers. You can assign the phone numbers to the individual handsets that
are registered with the base station as send and receive numbers (page 144).
Please note:
When making these entries, please remember the VoIP user data is case sensitive. When you enter
text, the first letter is capitalised by default. If necessary, press and hold the # key to switch
between upper and lower case and numbers.

With Gigaset.net you can call other Gigaset.net users directly over the Internet free of
charge, without setting up an account with a VoIP provider and without making any further
settings. You can find Gigaset.net subscribers by carrying out a name search in the
Gigaset.net directory (page 40).
The following appears in the handset's display:
§Yes§ Press the display key.
Enter your Gigaset.net name:
Enter the name that you would like to be listed under in the Gigaset.net direc-
tory and press §OK§. The name may contain up to 25 characters.

Version 2.1, 08.01.2007
Making calls with VoIP and the fixed line network
Making an external call
External calls are calls made via the public telephone network (fixed line network) or via
the Internet (VoIP). You generally decide which connection type you want to use for a spe-
cific call when you dial the number.
Use the talk key to select the type of connection and make the call
By briefly pressing or pressing and holding the call key c, you can determine the type of
connection for the call you want to make (fixed line network or VoIP).
Precondition: You enter the number without a line suffix (page 31) and have not defined
any dialling plans for this number.
~c Enter number (without suffix) and briefly press/press and hold the talk key.
A default connection is established on your phone (fixed line network or VoIP, page 116/
page 144).
¤Briefly press the talk key c if you want to make a call via this default connection.
¤Press and hold the talk key c if you want to make the call via the other connection
type.
If you have assigned a number of VoIP numbers to your phone, you can define which VoIP
number (VoIP account) is used for external calls from each specific handset (handset send
number, page 144).
Please note:
– You can conduct up to three separate external calls via your base station (using different hand-
sets): two calls via VoIP and one via the fixed line network.
– You can define dialling plans for certain numbers or area codes by determining the connection
and therefore the billing method to be used (cost control, see page 149) when these numbers are
dialled.
– Dialling with the directory (page 49), quick dial keys (page 108) or last number redial list
(page 56) saves repeated keying of phone numbers. You can modify or add to these numbers on
a call-to-call basis.
– If you use VoIP to make a call to the fixed line network, you may also have to dial the area code for
local calls (depending on the VoIP provider). You can avoid having to dial your own area code by
entering it into the configuration (page 148). Your area code is then added automatically when
you make local calls.
Please note:
If you are using a GAP compatible handset other than the Gigaset handsets C47H, S67H, S68H,
SL37H, S45 and C45, every call will be made via the standard connection, even if you press and hold
the call key. If you want to use the non-default connection to make a call, enter a star (*) at the end
of the number.

Selecting the connection type using display keys and making a call
Precondition: The display keys on your handset have been assigned §FixedLine§ and/or §IP§
(page 108).
§FixedLine§ / §IP§
Press the display key to select the connection type.
~s Enter the number or select from the directory.
c/ dPress the talk or handsfree key.
The number will always be called via the selected connection type.
Select and dial a connection via your line suffix
You can configure up to six VoIP numbers on your phone in addition to the fixed line net-
work number and the Gigaset.net number. A (line) suffix is assigned to each number (line)
of your phone:
uthe fixed line number has the suffix #0
uVoIP numbers have the suffixes #1 to #6 (page 133)
uand the Gigaset.net number has the suffix #9
When dialling, you can use this line suffix to specify the connection via which you would
like to call or be charged.
~ Enter the number of the party you wish to call.
~ Add the suffix for the connection (your phone number) through which you
wish to make and pay for the call.
cPress the talk key.
The connection is always made via the line with the assigned suffix, regardless of whether
you press the call key c briefly or press and hold.
Example: If you enter the number 1234567890#1 and press the talk key c, the number
1234567890 will be dialled via the first VoIP connection in the configuration.
Please note:
If you have pressed the §IP§ before dialling and ...
– ... dialled the number with suffix #1 to #6, your call will be made via the VoIP account assigned to
the suffix. The number will not be dialled if the suffix is invalid (e.g. no VoIP connection assigned).
– ... dialled the number without a suffix or with the suffix #0, your call will be made via the hand-
set's VoIP send number.
Do not enter a suffix if you have pressed the display key §FixedLine§ prior to dialling. Otherwise the suf-
fix will be dialled together with the number over the fixed line network. This may cause errors!
Please note:
If you specify a suffix for which no VoIP connection is configured in your base station, the VoIP status
code 0x33 will be displayed. The number will not be dialled.

Entering an IP address
You can also dial an IP address instead of a phone number using VoIP.
¤Press the star key * to separate the sections of the IP address
(e.g. 149*246*122*28).
¤If necessary press the hash # key to attach the SIP port number of the person you are
calling to the IP address (e.g. 149*246*122*28#5060).
You cannot dial IP addresses using a line suffix.
Cancelling the dialling operation
You can cancel the dialling operation with the end call key a.
Dialling emergency numbers – defining dialling plans
You can use the Web configurator to block certain numbers or to define which of your
numbers (fixed line network, VoIP) should be used to call specific numbers (Dialling Plans,
see page 149).
If you enter a number that has a defined dialling plan, the call will be made via the line
defined in the dialling plan – regardless of whether the call key is pressed briefly or pressed
and held. Any automatic area code will not be prefixed to the number.
Emergency numbers
Dialling plans for emergency numbers (e.g. the local emergency service number) are fac-
tory-set for certain countries. Emergency calls are then always made via the fixed line net-
work.
You cannot delete or deactivate these dialling plans. However, you can change the connec-
tion through which each emergency number should be called (e.g. if the phone is not con-
nected to the fixed line network). You must make sure that the VoIP provider for the
selected connection supports emergency calls.
If your phone does not have default dialling plans for emergency calls, you should define
the rules yourself (page 149). Assign them to a connection that you know supports emer-
gency calls. Emergency calls are always supported by fixed line networks.
Please note: If no rules are defined for emergency numbers and you have programmed an
automatic local area code (page 148), the code will be prefixed to emergency numbers as
soon as they are dialled via a VoIP connection.
Ending a call
aPress the end call key.
Please note:
Emergency numbers cannot be dialled if the keypad lock is activated. Before dialling, press and hold
the hash key #, to release the keypad lock.

The directory entries are usually sorted in alphabetical order. Spaces and digits take first
priority. The sort order is as follows:
1. Space
2. Digits (0–9)
3. Letters (alphabetical)
4. Other characters
To get round the alphabetical order of the entries, insert a space or a digit in front of the
name. These entries will then move to the beginning of the directory. Names that you have
prefixed with a star will move to the end of the directory.
Please note:
– To find out how to enter IP addresses, turn to page 32.
– If you want to dial a certain number using the same line connection each time, you can add the
relevant line suffix to the number in question (page 31).
– If you add a star (*) at the end of the number, the number will be dialled via the non-standard
connection (page 116), even if you press and release the c talk key. On condition that no dial-
ling plan has been defined for the number (page 149).

SMS mailboxes
The general mailbox is the default setting. Anyone can access this mailbox and it cannot
be protected by a PIN. You can additionally set up three personal mailboxes and protect
these with a PIN. Each mailbox is identified by a name and a "mailbox ID" (a kind of exten-
sion number).
Please note:
uIf you operate a number of devices (base stations) with SMS functionality on a single
phone line, then each SMS mailbox ID may only occur once. In this case you must also
change the preset ID of the general mailbox ("0").
uYou can only use personal mailboxes if your service provider supports this function. You
can tell whether this is the case by the addition of a star (*) to the number of a (preset)
SMS centre.
uIf you have forgotten your mailbox PIN, you can reset it by restoring the base station's
default settings. This will delete all SMS messages from all mailboxes.

(depending on your PABX).
If in doubt, test your PABX, e.g. by sending an SMS to your own number: once with and
once without the access code.

been assigned as a send or receive number can access the answer machine list (page 144).
After a new phone number is configured (a new VoIP account), it is first assigned to the
answer machine as a receive number.
Parallel calls
If a caller is connected to the answer machine and a second call for the answer machine
comes in on a different line (fixed line network or VoIP), the second caller hears the ringing
tone. The answer machine will answer the second call if:
uthe connection with the first caller has ended and
uthe set time period for the answer machine to answer a call (page 77) has expired.

messages are displayed in the handset's display for a few seconds.
Server not accessible!
The connection to the incoming e-mail server could not be established. This may have
the following causes:
– Incorrect entry for name of incoming e-mail server.
– Temporary problems with the incoming e-mail server (server is down or is not con-
nected to the Internet).

Many e-mail providers operate standard spam protection measures. E-mail messages classified as
spam are stored in a separate folder and are therefore not shown on the list of incoming mail.
Some e-mail providers allow you to deactivate spam protection or show spam e-mails on the list of
incoming mail.
Other e-mail providers may send a message to the Inbox when a new spam e-mail is received. This is
to inform you that a suspected spam e-mail has been received.
Date and sender of this mail are repeatedly updated, so that it is always displayed as a new message.

Gigaset C470-C475 IP / GBR / A31008-M1916-L101-1-7619 / messenger.fm / 7.2.08
Version 2.1, 08.01.2007
Messenger
The messenger on your phone makes instant messaging possible (immediate message
transfer, chatting). The phone supports the XMPP Messenger (Jabber).
Instant messaging refers to communication between "friends" on the Internet. Subscribers
exchange short messages, which are forwarded immediately. This gives rise to a flowing
"conversation" similar to chatting.
The precondition for this form of communication is that both subscribers have a connec-
tion to the messenger server of the same instant messaging provider. Therefore, both
subscribers must be "online". The messenger server forwards the messages to the recipi-
ent.
The subscribers to instant messaging are called buddies.
Most messenger servers allow you to create what are known as buddy lists. You can store
the buddies you want to chat to in the buddy list.
The messenger server informs you as soon as one of your buddies comes online or goes
offline. Offline means that the buddy has disconnected from the messenger server.
In addition to this, each buddy can determine their own (communication) status (state of
presence, see page 87), from which buddies can tell whether they are in the mood to chat
or wish to remain undisturbed.
The Web configurator on your phone gives you the following options:
uGo online (page 85).
uDisplay the list of your contacts (buddies) on the handset that you previously created
on the PC. This will indicate for each buddy whether they are available (online) and
ready to chat (state of presence, see page 87).
uExchange messages with your buddies. Your handset notifies you about new messages
with a flashing message key f and a beep.
uCall your buddies directly from your buddy list (page 92).
Preconditions for instant messaging:
uYou have registered with an instant messaging provider via the Web browser on your PC
and (optionally) agreed a Web name (nickname).
uYou have created a buddy list via the messenger client on the PC.
uYou have saved the messenger server address and your access data for the messenger
server (user ID, password) in the phone using the Web configurator (page 152). The
phone needs the data to establish a connection with the messenger server.

Version 2.1, 08.01.2007
Establishing a connection, going online
When you go online, your buddy list will be displayed on the handset and you will receive
messages from your buddies.
Only one of the handsets connected to the base station can connect to the messenger
server. You can then only "chat" on this handset.
An external call will interrupt the "chat", but you will still be online. You can continue your
chat after you end or reject the call.
Precondition: You have saved the messenger server address and your access data for the
messenger server (user ID and password) in the phone using the Web configurator
(page 152).
v ¢ îMessaging ¢Messenger
§Yes§ Press the display key to confirm the prompt.
The phone attempts to establish a connection. You are informed about the status of the
connection by messages on the display.
If the connection can be established, you are Online. The display will show the submenu for
your messenger. You can open your buddy list, send and receive messages and call your
buddies.
The following is displayed when the handset is in idle status:
You remain online until you set your status to Offline (page 86) or the connection to the
messenger server is terminated (page 93).
You also remain online if you press the end call key a.
If the connection cannot be established, you will receive an appropriate message. Please
try again later (page 93).
Please note:
If your instant messaging provider doesn't support the phone's messenger client, then you can open
an account with an open Jabber server and use the Web configurator to enter its address in your
phone. Many of these Jabber servers offer gateways to other messenger servers (e.g. AOL, ICQ, MSN,
Yahoo!).
You can find a list of Jabber servers and an overview of the gateways to other messenger servers on
the Internet at
http://www.jabber.org.
You can find information on setting up a Jabber account with connections from ICQ, MSN or Yahoo

Using the network mailbox
Some fixed network providers and VoIP providers offer answer machines on the network –
these are known as network mailboxes.
Each network mailbox accepts incoming calls made via the corresponding line (fixed line
network or corresponding VoIP phone number). To record all calls, you should therefore set
up network mailboxes for both the fixed line network and for each of your VoIP connec-
tions.
You need to have requested the network mailbox for your fixed line network connection
from your fixed line network provider. You can store the phone number for the fixed line
network mailbox in the base station.
You can activate/deactivate the network mailboxes for your VoIP connections using your
handset or the Web configurator. To do this, you only require the network mailbox phone
number.
Activating/deactivating network mailbox, entering numbers
You can manage the network mailboxes on your handset that are assigned to a receive
number on the handset.
v ¢ÐSettings ¢ Voice Mail ¢Network AM(s)

Registering handsets
You can register up to six handsets to your base station.
When you register a new Gigaset handset, the base station transfers the following entries
to its local directory to enable you to use online directories on your new handset:
uNet Directory for the currently active online directory (page 53)
uYellow Pages for the currently active online classified directory (page 53)
uGigaset.net for the Gigaset.net directory (page 40)
Precondition: The handset can send and receive directory entries (see handset operating
instructions).
Successful registration is acknowledged with a Data Transfer x entries received for this rea-
son.
Registering another Gigaset C47H handset on the Gigaset C470 IP/C475 IP
Before you can use your handset, you must register it to a base station.
You must initiate handset registration on the handset and on the base station.
The handset will change to idle status if registration was successful. The handset's internal
number is shown in the display e.g. Int 1. If not, repeat the procedure. Registration can take
up to one minute.
¤Select v ¢ÐSettings ¢Handset ¢Register H/Set on the handset.
¤Enter the system PIN of the base station (the default is 0000) and press §OK§. The display
shows e.g. Base 1 and flashes.
¤Within the next 60 seconds press and hold (for approx. 3 seconds) the registration/pag-
ing key (page 2) on the base station.
The handset is assigned the lowest available internal number (1-6). If a number of hand-
sets are registered on the base station, the internal number appears in the display after reg-
istration, e.g. INT 2. This means that the internal number 2 was assigned to the handset.
Please note:
– If a number of handsets are registered on your base station, you can simultaneously make two
calls via the Internet and one via the fixed line network Up to two additional internal connections
are also possible.
– Selecting the connection via the talk key (page 30) is not supported on GAP handsets. Therefore,
if you enter a number without a line suffix and without defining a dialling plan for the phone
number, it will be dialled via Default Line (page 116). If you enter a "*" (star) at the end of the phone
number, it will be dialled via the non-default connection.
– After registration, all the phone numbers for the phone will be assigned to the handset as receive
numbers. It will use the fixed line network number and the first VoIP number as send numbers.
For how to change the assignments, see page 144.

Setting the phone's IP address in LAN
The base station requires an IP address in order to be "recognised" by the LAN.
The IP address can be assigned to the base station automatically (by the router) or manu-
ally.
uIf performed dynamically, the router's DHCP server automatically assigns the base sta-
tion an IP address. The base station's IP address can be changed according to router set-
tings.
uIf performed manually/statically, you assign the base station a static IP address. This
may be necessary depending on your network configuration.
v ¢ÐSettings ¢Base ¢Local Network
~Enter the system PIN and press §OK§.
¤Change multiple line input:
IP Address Type:
Select Static or Dynamic.
If you select Static, you must manually define the IP address and the subnet mask for the
base station in the next lines, as well as the standard gateway and DNS server.
IP Address:
For IP Address Type = Dynamic:
The IP address that is currently assigned to the base station will be displayed. It cannot
be amended.
For IP Address Type = Static:
Enter the IP address that is to be assigned to the base station (overwriting the current
settings).

IP Configuration
Assigning the IP address
Make the necessary settings for operating your phone in your local network and to connect
it to the Internet. For more detailed explanations of the individual components/terms, see
the glossary (page 189).
¤Open the following Web page: Settings ¢IP Configuration.
¤In the Address Assignment area, select the IP address type.
Select Obtained automatically if you want your phone to be assigned a dynamic IP address by
a DHCP server in your local network. No further settings are necessary for the local net-
work.
Select Static if you would like to set up a static IP address for your phone. A static IP address
is useful, for example, if port forwarding or a DMZ is set up on the router for the phone.
The following fields are displayed when you select IP address type = Static:
IP address
Enter an IP address for your phone. This IP address allows your phone to be reached by
other subscribers in your local network (e.g. PC).
192.168.2.2 has been preset.
Please note the following:
– The IP address must be from the address block for private use that is used in the
router. This is generally in the range 192.168.0.1 – 192.168.255.254 with Subnet
mask 255.255.255.0. The subnet mask determines that the first three parts of the IP
address must be identical for all subscribers in your LAN.
– The static IP address must not belong to the address block (IP pool range) that is
reserved for the DHCP server of the router. It must also not be used by another device
on the router.
If necessary, check the settings on the router.
Subnet mask
Enter the subnet mask for your device's IP address. For addresses from the address block
192.168.0.1 – 192.168.255.254, the subnet mask 255.255.255.0 is generally used.
This is preconfigured when the phone is supplied.
Default gateway
Enter the IP address for the standard gateway, by means of which the local network is
connected with the Internet. This is generally the local (private) IP address for your
router (e.g. 192.168.2.1). Your phone requires this information to be able to access the
Internet.
192.168.2.1 has been preset.

Preferred DNS server
Enter the IP address for the preferred DNS server. DNS (Domain Name System) allows
you to assign public IP addresses to symbolic names. The DNS server is required to con-
vert the DNS name into the IP address when connection is being established to a server.
You can specify your router's IP address here. The router forwards phone address
requests to its DNS server.
192.168.2.1 has been preset.
Alternate DNS server (optional)
Enter the IP address for the alternative DNS server that should be used in situations
where the preferred DNS server cannot be reached.
Click Set to save the changes.
Click Cancel to reject the changes.
Allowing access from other networks
The default setting for your phone is set such that you can only access your phone's Web
configurator via a PC that is in the same local network as your phone. The subnet mask of
the PC must match that of the phone.
You can also allow access from PCs in other networks.
¤Open the following Web page: Settings ¢IP Configuration.
¤In the Remote Management area, activate the Yes option to permit access from other net-
works.
To deactivate remote access, click No. Access is then limited to PCs in your own local net-
work.
Access to the Web configurator services from other networks is only possible if your router
is set accordingly. The router must pass on the service requests from "outside" to Port 80
(default port) of the phone. Please also read the user guide for your router.
To establish a connection, the public IP address or the DNS name of the router and, where
applicable, the port number on the router must be indicated in the Web browser of the
remote PC.
Warning:
Expansion of access entitlement to other networks increases the risk of unauthorised access.
It is therefore recommended that you deactivate remote access again if you no longer require it.

Version 2.1, 08.01.2007
Area: Personal Provider Data
Enter the configuration data that is necessary for accessing your VoIP provider's SIP service.
You will receive this data from the VoIP provider.
The field names (Authentication Name etc.) listed in the following are standard names and
may change. If you have already downloaded the provider's general details ("Select VoIP Pro-
vider" button, see above), field entries will be replaced by provider-specific names to facili-
tate orientation (e.g. SIP-ID instead of Authentication Name).
Authentication Name
Specify the registration or authentication ID agreed with your VoIP provider. The regis-
tration ID serves as the access ID that your phone must specify when registering with
the SIP proxy/registrar server. The Authentication Name is mainly identical to the Username,
i.e. to your Internet phone number.
Authentication password
Enter the password that you have agreed with your VoIP provider in the Authentication
password field. The phone needs the password when registering with the SIP proxy/reg-
istrar server.
Username
Enter the caller ID for your VoIP provider account. This ID is usually identical to the first
part of your SIP address (URI, your Internet phone number).
Example: If your SIP address is "987654321@provider.com", enter "987654321" in User-
name.
Display name (optional)
Enter any name that should be shown in the other caller's display when you call them
via the Internet (example: Anna Sand). All characters in the UTF8 character set (Uni-
code) are permitted. The name must not exceed 32 characters.
If you do not enter a name, your Username VoIP phone number will be displayed.
Ask your VoIP provider if this feature is supported.
Area: General Provider Data
If you have downloaded the general settings for the VoIP provider from the Siemens con-
figuration server (page 134), then the fields in this area will be preset with the data from
the download. Generally speaking, you do not need to configure any settings in this area.
Domain
Specify the last part of your SIP address (URI) here.
Example: For the SIP address "987654321@provider.com", enter "provider.com" in
Domain.
Proxy server address
The SIP proxy is your VoIP provider's gateway server. Enter the IP address or the (fully-
qualified) DNS name of your SIP proxy server. Example: myprovider.com.
Proxy server port
Enter the number of the communication port that the SIP proxy uses to send and receive
signalling data (SIP port).
Port 5060 is used by most VoIP providers.

Version 2.1, 08.01.2007
Registrar server
Enter the (fully-qualified) DNS name or the IP address of the registrar server.
The registrar is needed when the phone is registered. It assigns the public IP address/
port number to your SIP address (Username@Domain) that were used by the phone at reg-
istration. With most VoIP providers, the registrar server is identical to the SIP server.
Example: reg.myprovider.com.
Registrar server port
Enter the communication port used in the registrar. It is mainly port 5060 that is used.
Registration refresh time
Enter the time intervals at which the phone should repeat the registration with the VoIP
server (SIP proxy) (a request will be sent to establish a session). The repeat is required
so that the entry of the phone in the tables of the SIP proxy is retained and the phone
can therefore be reached. The repeat will be carried out for all activated VoIP phone
numbers.
The default is 180 seconds.
If you enter 0 seconds, the registration will not be repeated periodically.
Area: Network
If your phone is connected to a router with NAT (Network Address Translation) and/or a fire-
wall, you must make some settings in this area so that your phone can be reached from the
Internet (i.e. can be addressed).
Through NAT, the IP addresses of subscribers in the LAN are concealed behind the public IP
address of the router.
For incoming calls
If port forwarding is activated or a DMZ is set up for the phone on the router, no special
settings are required for incoming calls.
If this is not the case, an entry in the NAT routing table (in the router) is necessary in order
for the phone to be reached. This entry is created when the phone is registered with the
SIP service. In the interest of security, this entry is automatically deleted at certain intervals
(session timeout). The phone must therefore confirm its registration at certain intervals
(see NAT refresh time, page 138), so that the entry stays in the routing table.
For outgoing calls
The phone needs its public address in order to receive caller voice data.
There are two possibilities:
uThe phone requests the public address from a STUN server on the Internet (Simple
Transversal of UDP over NAT). STUN can only be used with asymmetric NATs and non-
blocking firewalls.
uThe phone does not direct the connection request to the SIP proxy but to an outbound
proxy on the Internet that supplies the data packets along with the public address.
Please note:
If you have downloaded the general settings for your VoIP provider from the Siemens configuration
server (page 133), then some fields in this area will be preset with the data from the download (e.g.
the settings for the STUN server and outbound proxy).

Version 2.1, 08.01.2007
The STUN server and outbound proxy are used alternately to work around the NAT/firewall
in the router.
STUN enabled
Click Yes if you want your phone to use STUN as soon as it is used on a router with asym-
metric NAT.
STUN server
Enter the (fully-qualified) DNS name or the IP address of the STUN server on the Inter-
net.
If you selected Yes in the STUN enabled field, you must enter a STUN server here.
STUN port
Enter the number of the communication port on the STUN server. The default port is
3478.
STUN refresh time
Enter the time intervals at which the phone should repeat the registration with the
STUN server. The repeat is required so that the entry of the phone in the tables of the
STUN server is retained. The repeat will be carried out for all activated VoIP phone num-
bers.
Ask your VoIP provider for the STUN refresh time.
The default is 240 seconds.
If you enter 0 seconds, the registration will not be repeated periodically.
NAT refresh time
Specify the intervals at which you want the phone to update its entry in the NAT routing
table. Specify an interval in seconds that is a little smaller than the NAT session timeout.
As a rule you should not change the preconfigured value for the NAT refresh time.
Outbound proxy mode
Specify when the outbound proxy should be used.
Always
All signalling and voice data sent by the phone is sent to the outbound proxy.
Auto
Data sent by the phone is only sent to the outbound proxy when the phone is connected
to a router with symmetric NAT or blocking firewall. If the phone is behind an asymmet-
ric NAT, the STUN server is used.
If you have set STUN enabled = No or have not entered a STUN server, the outbound proxy
is always used.
Never
The outbound proxy is not used.
If you do not make an entry in the Outbound proxy field, the phone behaves independ-
ently of the selected mode, as with Never.
Outbound proxy
Enter the (fully qualified) DNS name or the IP address of your provider's outbound proxy.
Please note:
With many providers, the outbound proxy is identical to the SIP proxy.

nection on the handset and the Web configurator interface, e.g. during allocation of send
and receive numbers (page 144), for the call display (page 34).
¤Open the following Web page: Settings ¢Telephony ¢Connections.
¤In the Fixed Line Connection area, click Edit.
¤Enter your fixed line network number or the name of your choice (max. 16 characters)

Activating/deactivating the Gigaset.net connection
Your phone is assigned a Gigaset.net phone number on delivery. As soon as you have con-
nected your phone to the Internet, you can make calls using the Gigaset.net and receive
calls from other Gigaset.net subscribers, provided that your Gigaset.net connection has
been activated. You can deactivate the Gigaset.net connection.
¤Open the following Web page: Settings ¢Telephony ¢Connections. The list of connec-
tions will be displayed (see Figure 3 on page 132).
¤In the Gigaset.net area: use the option in the Active column to activate ( ) or deactivate
( ) the Gigaset.net connection.
Optimising voice quality for VoIP connections
You can make general and connection-specific settings to improve the voice quality for
VoIP telephony.
¤Open the following Web page: Settings ¢Telephony ¢Audio.
The voice quality for VoIP connections is mainly determined by the voice codec used for
transferring the data and the available bandwidth of your DSL connection.
In the case of the voice codec, the voice data is digitalised (coded / decoded) and com-
pressed. A "better" codec (better voice quality) means more data needs to be transferred,
i.e. perfect voice data transfer requires a DSL connection with a larger bandwidth.
The following voice codecs are supported by your phone:
G.722
If you register an HDSP capable handset (HDSP= High Definition Sound Performance)
with your base station, the calls you make using the handset via G.722 VoIP connections
will have a fantastic sound quality. Gigaset handsets S67H and SL37H, for e.g., are HDSP
capable.
The broadband speech codec G.722 works at the same bit rate as G.711 (64 kbit/s per
speech connection) but with a higher sampling rate.
G.711 a law / G.711 µ law
Excellent voice quality (comparable with ISDN). The necessary bandwidth is 64 kbit/s
per voice connection.
G.726
Good voice quality (inferior to that with G.711 but better than with G.729).
Your phone supports G.726 with a transmission rate of 32 kbit/s per voice connection.
Please note:
If you do not use your Gigaset.net connection for six weeks, it is automatically deactivated. You can-
not be reached for calls from the Gigaset.net.
The connection is reactivated:
– as soon as you start a search in the Gigaset.net directory (page 40) or
– make a call via Gigaset.net, i.e. dial a number ending in #9 (two attempts may be necessary) or
– activate the connection via the Web configurator as described above.

Version 2.1, 08.01.2007
G.729
Average voice quality. The necessary bandwidth is less than 8 kbit/s per voice connec-
tion.
Both sides of a phone connection (caller/sender side and receiver side) must use the same
voice codec. The voice codec is negotiated between the sender and the recipient when
establishing a connection.
You can influence the voice quality by selecting (bearing in mind the bandwidth of your
DSL connection) the voice codecs your phone is to use, and specifying the order in which
the codecs are to be suggested when a VoIP connection is established.
Area: Settings for Bandwidth
The settings in this area influence all VoIP connections (VoIP phone numbers).
Allow 1 VoIP call only
Generally speaking you can make two VoIP calls at the same time on your phone. If,
however, your DSL connection has a narrow bandwidth, there may be problems if two
VoIP calls are made at the same time. The data is no longer transferred properly (long
voice delay, data losses etc.).
¤Activate Yes next to Allow 1 VoIP call only to prevent any further parallel VoIP phone
connections being established.
¤If you wish to permit two VoIP connections, activate the No option.
Voice Quality
Default settings for the codecs used are stored in your phone: one setting optimised for
narrow and one for wide bandwidths.
¤Activate one of the options Optimized for low bandwidth / Optimized for high bandwidth if
you wish to accept a default setting for all VoIP connections. The settings are shown
in the Settings for Connections area and cannot be changed.
¤Activate the Own Codec preference option if you wish to select and set connection-spe-
cific voice codecs yourself (see "Area: Settings for Connections").
Please note: If only one VoIP connection is permitted, the following VoIP network services are no
longer available:
– Call waiting
Call waiting is not displayed during a call via VoIP
– External consultation call from a VoIP call
– Toggling and initiating a conference call via VoIP

Version 2.1, 08.01.2007
Area: Settings for Connections
In this area you can make specific settings for each of your VoIP phone numbers.
You can make the following settings for each VoIP phone number configured on your
phone:
Volume for VoIP Calls
Depending on the VoIP provider, it is possible that the received voice/earpiece volume is
too low or too high, so that adjusting the volume via the handset is not adequate.
Specify whether the received volume range is too high or too low. The following options
are available:
Low
Voice/earpiece volume is too high. Activate this option to reduce the volume by 6 dB.
Normal
The voice/earpiece volume does not need to be raised/lowered.
High
Voice/earpiece volume is too low. Activate this option to increase the volume by 6 dB.
Voice codecs
Precondition: The Own Codec preference option is activated for the Voice Quality in the
Settings for Bandwidth area.
Select the voice codecs your phone is to use, and specify the order in which the codecs
are to be suggested when a VoIP connection is established via this VoIP phone number.
¤Apply the voice codecs that your phone is to suggest with outgoing calls into the
Selected codecs list.
To do this, in the Available codecs list click the voice codec that you want to apply (you
can mark several entries using the Shift key or the Ctrl key). Click <Add.
¤Move the voice codecs that you do not want the phone to use into the Available codecs
list.
Also, select the voice codecs in the Selected codecs list (see above) and click Remove>.
¤Sort the voice codecs in the Selected codecs list into the order in which they should be
suggested to the receiving device when a connection is established. To do this, use
the Up and Down buttons.
When establishing a VoIP connection, the phone suggests the 1st voice codec in the
Selected codecs list to the receiving device to begin with. If the receiving device does not
accept the codec (e.g. because it is not supported), the 2nd voice codec on the list is
suggested, and so on.
If the receiving device does not accept any of the voice codecs in the Selected codecs list,
the connection is not established. An appropriate message will be displayed on the
handset.
Please note:
– You should only deactivate codecs (put them in the Available codecs list) if there is a particular rea-
son. The more codecs that are deactivated, the greater the danger that calls will not be able to be
established due to unsuccessful codec negotiations.
– With incoming calls, all supported voice codecs are always permitted.

a synthetic noise generated in the receiver.
Please note: "Silence Suppression" can sometimes lead to deterioration in the voice qual-
ity.
¤In the Enable Annex B for codec G.729 field, state whether the transmission of data packets
during pauses should be suppressed when using the G.729 codec, (activate Yes).

Voice quality and infrastructure
A Gigaset C470 IP or C475 IP will allow you to make calls with good voice quality via the
Internet.
However, your phone's performance with VoIP – and therefore the voice quality – also
depends on the properties of the entire infrastructure.
The following VoIP provider components are just some of the things that can influence per-
formance :
uRouter
uDSLAM
uDSL transmission line and speed
uConnection paths over the Internet
uIf necessary, other applications that also use the DSL connection
In VoIP networks, voice quality is affected by various things including the "quality of serv-
ice" (QoS). If the entire infrastructure demonstrates QoS, voice quality is better (fewer
delays, less echoing, less crackling etc.).
If, for example, the router does not have QoS, then the voice quality is not as good. Please
see the specialist documentation for further information.
Please note:
You should observe the following for good voice quality:
– When making calls using VoIP, avoid performing other Internet activities (e.g. surfing the Inter-
net).
– Irrespective of the codec used and the network capacity utilisation, please note that voice delays
can occur.

Call Forwarding to activate VoIP connections
You can forward calls to your VoIP numbers and to your Gigaset.net number.
You can forward calls to your VoIP numbers to any external number (VoIP, fixed line net-
work or mobile network number). The forwarding is done via a VoIP connection.
You can forward calls to your Gigaset.net number within the Gigaset.net, i.e. to another
Gigaset.net number.
You can define if and when calls to your Gigaset.net number and some of your VoIP num-
bers (VoIP account) should be forwarded to this VoIP number.
You can also use the handset to define call forwarding and activate/deactivate it, see
page 47.
¤Open the following Web page: Settings ¢Telephony ¢Call Forwarding.
The display shows a list of all your VoIP connections and your Gigaset.net number.
Connections
Select the name you have assigned to the VoIP number, or select Gigaset.net.
When
Select when a call to this VoIP number should be forwarded: When busy / No reply / Always.
Select Off to deactivate call forwarding.
Call number
Enter the phone number to which the calls should be forwarded. Please note that you
may have to enter the area code when forwarding to a fixed line network number in the
same area (depending on your VoIP provider and the setting for the automatic area
code, see page 148).
The settings only affect the selected phone number.
Setting DTMF signalling for VoIP
DTMF signalling is required, for example, for querying and controlling certain network
mailboxes via digit codes or for remote operation of the integrated answer machine
(Gigaset C475 IP).
To send DTMF signals via VoIP you must first define how key codes should be converted
into and sent as DTMF signals: as audible information via the speech channel or as "SIP Info"
message.
Ask your VoIP provider which type of DTMF transmission it supports.
¤Open the following Web page: Settings ¢Telephony ¢Advanced Settings.
In the DTMF over VoIP connections area, make the required settings for sending DTMF signals.
¤Activate Audio or RFC 2833, if DTMF signals are to be transmitted acoustically (in voice
packets).
¤Activate SIP Info if DTMF signals are to be transmitted as code.
¤Now click Set to save your settings.

Version 2.1, 08.01.2007
Defining recall key functions for VoIP (hook flash)
Your VoIP provider may support special performance features. To make use of these fea-
tures, your phone needs to send a specific signal (data packet) to the SIP server. You can
assign this "signal" to your phone's recall key.
If you press the recall key during a VoIP call the signal will be sent to the server.
¤Open the following Web page: Settings ¢Telephony ¢Advanced Settings.
¤Enter the data you received from your VoIP provider into the fields Application Type and
Application Signal in the Hook Flash (R-key) area.
¤Now click Set to save your settings.
The setting for the recall key applies to all registered handsets.
Defining local communication ports for VoIP
¤Open the following Web page: Settings ¢Telephony ¢Advanced Settings.
In the Listen ports for VoIP connections area, specify which local ports the telephone is to use
for VoIP telephony. The ports must not be used by any other subscriber in the LAN.
SIP port
Specify the local communication port that the phone should use to send and receive sig-
nalling data. Specify a number between 1024 and 49152. The default port number for
SIP signalling is 5060.
RTP port
Specify the local communication port that the phone should use to receive voice data.
Enter an even number between 1024 and 49152. The port number must not be the
same as the port number in the SIP port field. If you enter an odd number, the next low-
est even number will be selected automatically (e.g. you enter 5003, then 5002 is set
automatically). The default port number for voice transmission is 5004.
Use random ports
Click Yes if you do not want the phone to use fixed ports for SIP port and RTP port, but
rather to use any free ports.
The use of random ports makes sense if you want several phones to be operated on the
same router with NAT. The phones must then use different ports so that the router's NAT
is only able to forward incoming calls and voice data to one (the intended) phone.
If you click No, the phone will use the ports specified in SIP port and RTP port.
¤Now click Set to save your settings.
Please note:
The settings for DTMF signalling apply to all VoIP connections (VoIP accounts).

nated.
To learn how to forward a call when you have activated No, please see page 48.
Preferred Refer To
Define the protocol (the contents of the "Refer To" information) that should be used with
preference when forwarding calls:
Target’s contact info
This protocol is recommended for "closed" networks (internal company and business
networks).
Original URL
This protocol is recommended when the base station is connected to the Internet via a
router with NAT.
Automatic Refer To
If you activate Yes, the base station will attempt to determine the best protocol automat-
ically.
If the base station cannot determine the best protocol, it will use the protocol defined
in Preferred Refer To.
¤Now click Set to save your settings.
Setting area code predialling
On the base station, save the complete code (with international code) for the area in which
you are using the phone.
For VoIP calls you must generally always dial the area code – even for local calls. You can
save the need to dial the area code for local calls by setting your phone to prefix this code
for all VoIP calls made in the same local area.
For calls made via VoIP, the area code entered is then prefixed to all numbers that do not
start with 0 – even when dialling numbers from the directory and other lists. Exceptions:
Numbers for which you have defined dialling plans (page 149).
¤Open the following Web page: Settings ¢Telephony ¢Dialling Plans.

¤Click Set to save the settings.
Defining dialling plans – cost control
You can define dialling plans to reduce costs:
uYou can define the connection (one of your VoIP accounts, the fixed line network)
through which calls to specific numbers should be made and paid for.
If you enter just a few digits (e.g. local area, national or mobile network code) any call
to a number beginning with these digits will be made via the elected connection.
uYou can block specific numbers, i.e. your phone will not establish a connection to these
numbers (e.g. 0900 numbers).
These dialling plans apply to all registered handsets. The settings for the default connec-
tion (briefly press/press and hold c) and the send numbers of handsets do not apply to
numbers governed by a dialling plan.
Tips:
uCompare the rates for long-distance calls (especially for international calls) offered by
your fixed line network and VoIP providers, and determine which connection should be
used specifically for these countries/locations, e.g. a dialling plan for the Phone Number
"0033" would apply to every call made to France.
uUse dialling plans to define that numbers starting with a call-by-call number are always
made via your fixed line network connection. To do so, enter the call-by-call number in
the Phone Number field.
Please note:
uThe area code will also be prefixed to VoIP calls made to emergency numbers if there
are no defined dialling plans for these numbers.
uThe numbers of your network mailbox saved in the base station are not prefixed with
a code (page 151).
Please note:
You can override dialling plans, with the exception of blocks, as follows:
– Dial the number with a line suffix (e.g. 123456789#3, see page 31).
– Before you enter the number, define a different connection type by pressing the display keys
§FixedLine§ / §IP§ (page 108).
If, for example, you press §FixedLine§, the number will be dialled via the fixed line network, even if
the dialling plan states that a VoIP connection should be used.
Area code predialling is not prefixed to numbers governed by a dialling plan (page 148).

These dialling plans cannot be deleted, deactivated or blocked. However, you can change
the Connection Type.
This should only be changed if the phone is not connected to the fixed line network. If you
choose a VoIP connection, please make sure the VoIP provider supports emergency calls.
If no emergency numbers are set by default, you should define dialling plans for emer-
gency numbers yourself and assign them to a connection of which you know that it sup-
ports emergency calls. Emergency calls are always supported by fixed line networks.
Activating/deactivating network mailbox, entering numbers
Many fixed network providers and VoIP providers offer answer machines on the network –
these are know as network mailboxes.
Each network mailbox accepts incoming calls made via the corresponding line (fixed line
network or corresponding VoIP phone number).
You can enter the relevant network mailbox for each configured connection (VoIP, fixed
line network) via the Web configurator. You can activate or deactivate the network mailbox
for your VoIP connections.

Saving messenger access data
The messenger client in your base station enables instant messaging (immediate mes-
sage transfer, chatting). The phone supports the XMPP messenger (Jabber).
In order for you to use your phone's messenger to "go online" and "chat" on the Internet,
the access data of a messenger server must be saved on your phone.
Your phone is already registered with the Gigaset.net Jabber server. An account has been
assigned to your phone. You can chat to other Gigaset.net subscribers via this account. To
do this you need to create a buddy list on the PC (see "Setting up Gigaset.net Jabber
account" on page 153).
You can also register with another instant messaging provider that supports XMPP Messen-
ger (Jabber). You must then save the messenger server address and your access data on
your phone.
You can define a Resource name and a Priority for your phone. Both are required if you are
logged in (online) with the messenger server with several devices (phone, desktop PC and
laptop) at the same time using the same Jabber ID.
The Resource name is used to distinguish between these devices. The phone cannot log in
with the messenger server if it does not have a resource name.
You should assign a Priority as each message will only be sent to one device for each Jabber
ID. The Priority determines which of the devices receives the message.
Example: You are online using one of your phone's handsets and your PC both at the same
time. You have assigned your phone (Resource name "phone") Priority 5 and your PC
(Resource name "PC") Priority 10. In this case, any message addressed to your Jabber ID will
be sent to your phone.
¤Open the following Web page: Settings ¢Messaging ¢Messenger.
Please note:
– You need to have requested the network mailbox for your fixed line network connection from
your fixed line network provider.
– You can read how to enter the network mailbox numbers and activate/deactivate network mail-
boxes on page 94.

Setting up Gigaset.net Jabber account
Your phone is already registered with the Gigaset.net Jabber server. An account has been
assigned to your phone.
In order to chat with other Gigaset.net subscribers via this account, you must transfer the
required Gigaset.net subscribers to a contact list (buddy list) on your PC. You can use any
conventional Jabber client for this (e.g. PSI, Miranda; see e.g. http://www.swissjabber.ch).
In order to use the Gigaset.net Jabber account, proceed as follows:
¤Start the Web configurator, open the Settings ¢Messaging ¢Messenger Web page and
select the Messenger Account Gigaset.net field. Your account data is displayed in Jabber ID
and Authentication password. You will need these to create a buddy list via the Jabber cli-
ent on the PC.
¤Start your Jabber client on the PC.
¤Enter your Gigaset.net Jabber ID on the Jabber client as a new account. The Jabber ID con-
sists of your Gigaset.net number and "@jabber.gigaset.net"
Example: 12345678901#9@jabber.gigaset.net
¤Then enter your Authentication password.
Please note:
–Do not select the option "Create new account". Your Gigaset.net Jabber account has already been
created in Gigaset.net.

Starting a firmware update
If necessary, you can load updates of the base station firmware onto your phone.
The server on which Siemens makes new firmware versions available for your base station
is set by default. The URL of the Internet server is displayed in the Data server field.
You should only change this URL under exceptional circumstances (e.g. if requested to do
so due to erroneous behaviour). This address is also used to load provider information from
the Internet. You should therefore make a note of the default URL before you overwrite it.
Otherwise, you will only be able to reactivate the default URL by resetting the base station
back to the factory settings (page 114).
Please note:
A table with possible status codes and their meaning can be found in the appendix on page 168.
Please note:
– When updating from the Internet, checks are made to ensure that no newer version of the
firmware exists. If this is not the case, the operation is terminated.
– The firmware is only loaded from the Internet if you have not entered a local file in the User defined
firmware file field prior to the update.

Copy date and time from time server
The date and time are shown in the idle display of registered handsets. They are important,
for example, for stating the correct time in the calls list and for the "alarm clock" function.
There are two methods for updating the time and date on your base station: manually with
one of the registered handsets (page 13) or automatically by synchronisation with a time
server on the Internet.
Activate/deactivate synchronisation with a time server as follows:
¤Open the following Web page: Settings ¢Miscellaneous.
¤In the Automatic adjustment of System Time with Time Server field select Yes to activate syn-
chronisation between base station and a time server. If you select No the base station
will not adopt time settings from a time server. In this case you should set the time and
date manually using a handset.
¤The Last synchronisation with time server field shows the last time when the base station
compared time and date settings with a time server.
¤In the Time Server field, enter the Internet address or name of the time server from which
the base station should adopt its time and date settings. The time server
"europe.pool.ntp.org" is set as default on the base station. You can overwrite the set-
ting.
¤From the Country list, select the country in which your base station is being operated.
¤The Time Zone field shows the valid time zone for the Country. It shows the deviation
between local time (not summer time) and Greenwich Mean Time (GMT).
If a country is divided into various time zones, they will all appear in the list. Select the
appropriate Time Zone for the base station from the list.
¤The Automatically adjust clock to summer-time changes field will be displayed if your time
zone differentiates between summer time and winter time.
Activate On if you want the time to change automatically to summer time or winter time
when summer time begins and ends respectively.
Activate Off if you do not want to change to summer time.

Version 2.1, 08.01.2007
Please note: If the date and time are updated by a time server that automatically
switches between summer time and standard time, you must always activate Off here.
¤Click Set to save the settings in your phone.
Once you have activated synchronisation, the time and date will be compared with a time
server as soon as an Internet connection is established.
Synchronisation will usually occur once a day (at night) if synchronisation is activated. Any
additional synchronisation will take place only after each new system start of the base sta-
tion (e.g. after a firmware update or a power cut).
If you register a new handset on your base station it will assume the time and date of the
base station without any additional synchronisation with the time server.
Date and time settings are transferred to every handset after synchronisation.
Querying the phone status
General information about your phone is displayed.
¤In the menu list, click the Status tab.
The following information is displayed:
IP Configuration
IP address
The phone's current IP address within the local network. For assigning the IP address,
see page 130.
MAC address
The phone's device address.
Software
Firmware version
Version of the firmware currently downloaded. You can download updates of the
firmware on your phone (page 116). Firmware updates are available on the Internet.
EEPROM version
Version of your phone's EEPROM storage chip (page 192).
Please note:
– The default time server "europe.pool.ntp.org" will remain stored in the base station even if you
overwrite it. If you delete your time server from the Time Server field and synchronisation is still
activated, the base station will return to synchronisation with the default time server. However, it
will no longer appear in the Time Server field.
– The base station will return to synchronisation with the default time server if you have entered
your own time server in the Time Server field and the base station is unable to synchronise time
and date for ten consecutive attempts.
– If you have deactivated synchronisation with a time server, and if the date and time are not set on
any handset, then the base station will attempt to reference date and time settings from the CLIP
information of an incoming call.

¥Check your router's cable connection to the Internet.
¥Check whether the phone is connected to the LAN. Send a ping command, e.g. from your PC, to
the phone (ping s<local IP address of the phone>). It may be that no IP address could be assigned
to the phone or a permanently set IP address is already assigned to another LAN subscriber. Check
the settings on the router, you may have to activate the DHCP server.
You cannot make calls via VoIP. Either Provider registration failed! or Registration failed is shown.
¥First wait a few minutes. This is often a short-term event that corrects itself after a short time.

2. The general settings for your VoIP provider are incomplete or incorrect (incorrect server address).
¥Start the Web configurator and check the settings.
You cannot make calls via VoIP. The display shows IP configuration error: xxx or VoIP config.error: xxx
(xxx = VoIP status code).
You are trying to make a call via a VoIP connection that is not properly configured.
¥Start the Web configurator and check the settings. Possible status codes and their meanings are
listed on page 168.
The phone does not dial an entered number. The display shows Not possible!.

VoIP status codes
If you have problems with your VoIP connections, activate the Show Stat. on HS function
(page 119, page 159). You will then receive a VoIP status code that will support you in
problem analysis. Also enter the code during problem analysis by the Service department.
In the following tables you will find the meanings of the most important status codes and
messages.
Status
code
Meaning
0x31 IP configuration error: IP domain not entered.
0x33 IP configuration error: SIP user name (Authentication Name) not entered.
This is shown, for example, when dialling with a line suffix, if no connection is configured
for the suffix on the base station.
0x34 IP configuration error: SIP password (Authentication password) not entered.
0x300 The called party can be reached under several phone numbers. If the VoIP provider supports
this, a list of the phone numbers is transmitted as well as the status code. The caller can
select to which number he wants to make the connection.
0x301 Permanently redirected.
The called party can no longer be reached under this number. The new number is trans-
ferred to the phone together with the status code, and the phone then no longer accesses
the old number but dials the new address immediately.
0x302 Temporarily redirected.
The phone is informed that the called party cannot be reached under the number dialled.
The duration of redirecting is time-limited. The phone is also notified of the duration of
redirecting.
0x305 The query is sent to a different "proxy server", e.g. to balance out incoming queries. The
phone will make the same query once again to another proxy server. This is not a redirec-
tion of the address per se.
0x380 Other service:
The query or the call could not be made. But the phone is notified what other options there
are to be able to connect the call.
0x400 Wrong call
0x401 Not authorised
0x403 The requested service is not supported by the VoIP provider.
0x404 Wrong phone number.
No caller on this number.
Example: In a local call you have not dialled the area code although your VoIP provider does
not support local calls.
0x405 Method not permitted.
0x406 Not acceptable.
The requested service cannot be provided.
0x407 Proxy authentication required.
0x408 The party cannot be reached (e.g. account has been deleted).
0x410 The requested service is not available from the VoIP provider.

0x415 Query format is not supported.
0x416 URI is faulty.
0x420 Incorrect ending
0x421 Incorrect ending
0x423 The requested service is not supported by the VoIP provider.
0x480 The dialled number is temporarily unavailable.
0x481 The recipient is not available.
0x482 Double service query
0x483 Too many "hops":
The query was rejected because the service server (proxy) has decided that this query has
already passed through too many service servers. The maximum number was previously
specified by the original sender of the query.
0x484 Wrong number:
In most cases this response means that you have simply omitted one or more digits in the
phone number.
0x485 The URI dialled is not unique and cannot be processed by the VoIP provider.
0x486 The called party is busy.
0x487 General faults:
The call was interrupted before a call was established. The status code confirms receipt of
the interruption signal.
0x488 The server cannot process the query because the data entered in the media description is
not compatible.
0x491 The server notifies that the query will be processed as soon as a previous query has been
completed.
0x493 The server rejects the query because the phone cannot decrypt the message. The sender
has used an encryption method that neither the server nor the receiver phone can decrypt.
0x500 The proxy or the receiving device has discovered a fault while executing the query, which
makes further execution of the query impossible. In this case, the caller or the phone dis-
plays the fault and repeats the query after a few seconds. The number of seconds after
which the query can be repeated may be transmitted to the caller or phone by the receiving
device.
0x501 The query cannot be processed by the recipient because the recipient does not have the
functionality that the caller requires. If the recipient understands the query but does not
process it because the sender does not have the necessary rights or the query is not permit-
ted in the current context, a 405 is sent instead of 501.
0x502 In this case, the receiving device that transmits this error code is a proxy or a gateway and
has received an invalid response from its gateway via which this query is to be processed.

0x503 The query cannot currently be processed by the receiving device or the proxy because the
server is either overloaded or is being serviced. If it is possible for the query to be repeated
in the foreseeable future, the server informs the caller or the phone of this.
0x504 Time limit at the gateway

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing
it is not allowed.
[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library
Public License, version 2, hence the version number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By con-
trast, the GNU General Public Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some specially designated software
packages--typically libraries--of the Free Software Foundation and other authors who decide to use it.
You can use it too, but we suggest you first think carefully about whether this license or the ordinary
General Public License is the better strategy to use in any particular case, based on the explanations
below.
When we speak of free software, we are referring to freedom of use, not price. Our General Public
Licenses are designed to make sure that you have the freedom to distribute copies of free software
(and charge for this service if you wish); that you receive source code or can get it if you want it; that
you can change the software and use pieces of it in new free programs; and that you are informed that
you can do these things.
To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or
to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if
you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for a fee, you must give the reci-
pients all the rights that we gave you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide complete object files to the recipients,
so that they can relink them with the library after making changes to the library and recompiling it.
And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this
license, which gives you legal permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no warranty for the free library.
Also, if the library is modified by someone else and passed on, the recipients should know that what
they have is not the original version, so that the original author's reputation will not be affected by
problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free program. We wish to make
sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive
license from a patent holder. Therefore, we insist that any patent license obtained for a version of the
library must be consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the ordinary GNU General Public License.
This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite
different from the ordinary General Public License. We use this license for certain libraries in order to
permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a shared library, the combination
of the two is legally speaking a combined work, a derivative of the original library. The ordinary Gene-
ral Public License therefore permits such linking only if the entire combination fits its criteria of free-
dom. The Lesser General Public License permits more lax criteria for linking other code with the library.
We call this license the "Lesser" General Public License because it does Less to protect the user's free-
dom than the ordinary General Public License. It also provides other free software developers Less of
an advantage over competing non-free programs. These disadvantages are the reason we use the
ordinary General Public License for many libraries. However, the Lesser license provides advantages in
certain special circumstances.

Version 2.1, 08.01.2007
For example, on rare occasions, there may be a special need to encourage the widest possible use of
a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free library does the same job as widely used
non-free libraries. In this case, there is little to gain by limiting the free library to free software only,
so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs enables a greater number
of people to use a large body of free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU operating system, as well as its
variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that
the user of a program that is linked with the Library has the freedom and the wherewithal to run that
program using a modified version of the Library.
The precise terms and conditions for copying, distribution and modification follow. Pay close attention
to the difference between a "work based on the library" and a "work that uses the library". The former
contains code derived from the library, whereas the latter must be combined with the library in order
to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other program which contains a notice
placed by the copyright holder or other authorized party saying it may be distributed under the terms
of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data prepared so as to be conveniently lin-
ked with application programs (which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has been distributed under
these terms. A "work based on the Library" means either the Library or any derivative work under copy-
right law: that is to say, a work containing the Library or a portion of it, either verbatim or with modi-
fications and/or translated straightforwardly into another language. (Hereinafter, translation is inclu-
ded without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications to it. For a
library, complete source code means all the source code for all modules it contains, plus any associa-
ted interface definition files, plus the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered by this License; they are
outside its scope. The act of running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based on the Library (independent of
the use of the Library in a tool for writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source code as you receive
it, in any medium, provided that you conspicuously and appropriately publish on each copy an appro-
priate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License
and to the absence of any warranty; and distribute a copy of this License along with the Library.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer war-
ranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based
on the Library, and copy and distribute such modifications or work under the terms of Section 1 above,
provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that you changed the files and
the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms
of this License.
d) If a facility in the modified Library refers to a function or a table of data to be supplied by an appli-
cation program that uses the facility, other than as an argument passed when the facility is invoked,
then you must make a good faith effort to ensure that, in the event an application does not supply
182
Appendix
Gigaset C470 IP/C475 IP – Free software
Gigaset C470-C475 IP / GBR / A31008-M1916-L101-1-7619 / appendix.fm / 7.2.08
Version 2.1, 08.01.2007
such function or table, the facility still operates, and performs whatever part of its purpose remains
meaningful.
(For example, a function in a library to compute square roots has a purpose that is entirely well-defi-
ned independent of the application. Therefore, Subsection 2d requires that any application-supplied
function or table used by this function must be optional: if the application does not supply it, the
square root function must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not
derived from the Library, and can be reasonably considered independent and separate works in them-
selves, then this License, and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of this License, whose permissions
for other licensees extend to the entire whole, and thus to each and every part regardless of who
wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely
by you; rather, the intent is to exercise the right to control the distribution of derivative or collective
works based on the Library.
In addition, mere aggregation of another work not based on the Library with the Library (or with a
work based on the Library) on a volume of a storage or distribution medium does not bring the other
work under the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License
to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a
newer version than version 2 of the ordinary GNU General Public License has appeared, then you can
specify that version instead if you wish.) Do not make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General
Public License applies to all subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the Library into a program that is not
a library.
4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object
code or executable form under the terms of Sections 1 and 2 above provided that you accompany it
with the complete corresponding machine-readable source code, which must be distributed under the
terms of Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated place, then offering
equivalent access to copy the source code from the same place satisfies the requirement to distribute
the source code, even though third parties are not compelled to copy the source along with the object
code.
5. A program that contains no derivative of any portion of the Library, but is designed to work with
the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in
isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library creates an executable that is a deriva-
tive of the Library (because it contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file that is part of the Library, the
object code for the work may be a derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be linked without the Library, or if the work
is itself a library. The threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data structure layouts and accessors, and small
macros and small inline functions (ten lines or less in length), then the use of the object file is unres-
tricted, regardless of whether it is legally a derivative work. (Executables containing this object code
plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work
under the terms of Section 6.
Any executables containing that work also fall under Section 6, whether or not they are linked directly
with the Library itself.

6. As an exception to the Sections above, you may also combine or link a "work that uses the Library"
with the Library to produce a work containing portions of the Library, and distribute that work under
terms of your choice, provided that the terms permit modification of the work for the customer's own
use and reverse engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the Library is used in it and that the
Library and its use are covered by this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the copyright notice for the Library
among them, as well as a reference directing the user to the copy of this License. Also, you must do
one of these things:
a) Accompany the work with the complete corresponding machine-readable source code for the
Library including whatever changes were used in the work (which must be distributed under Sections
1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-
readable "work that uses the Library", as object code and/or source code, so that the user can modify
the Library and then relink to produce a modified executable containing the modified Library. (It is
understood that the user who changes the contents of definitions files in the Library will not necessa-
rily be able to recompile the application to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one
that (1) uses at run time a copy of the library already present on the user's computer system, rather
than copying library functions into the executable, and (2) will operate properly with a modified ver-
sion of the library, if the user installs one, as long as the modified version is interface-compatible with
the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three years, to give the same user the
materials specified in Subsection 6a, above, for a charge no more than the cost of performing this dis-
tribution.
d) If distribution of the work is made by offering access to copy from a designated place, offer equiva-
lent access to copy the above specified materials from the same place.
e) Verify that the user has already received a copy of these materials or that you have already sent this
user a copy.
For an executable, the required form of the "work that uses the Library" must include any data and
utility programs needed for reproducing the executable from it. However, as a special exception, the
materials to be distributed need not include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies the executable.
It may happen that this requirement contradicts the license restrictions of other proprietary libraries
that do not normally accompany the operating system. Such a contradiction means you cannot use
both them and the Library together in an executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side in a single library
together with other library facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on the Library and of the other library
facilities is otherwise permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based on the Library, uncombined
with any other library facilities. This must be distributed under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of it is a work based on the
Library, and explaining where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provi-
ded under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the
Library is void, and will automatically terminate your rights under this License. However, parties who
have received copies, or rights, from you under this License will not have their licenses terminated so
long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed it. However, nothing else
grants you permission to modify or distribute the Library or its derivative works. These actions are pro-
hibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or
any work based on the Library), you indicate your acceptance of this License to do so, and all its terms
and conditions for copying, distributing or modifying the Library or works based on it.

10. Each time you redistribute the Library (or any work based on the Library), the recipient automati-
cally receives a license from the original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent infringement or for any other
reason (not limited to patent issues), conditions are imposed on you (whether by court order, agree-
ment or other wise) that contradict the conditions of this License, they do not excuse you from the con-
ditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under
this License and any other pertinent obligations, then as a consequence you may not distribute the
Library at all. For example, if a patent license would not permit royalty-free redistribution of the
Library by all those who receive copies directly or indirectly through you, then the only way you could
satisfy both it and this License would be to refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the
balance of the section is intended to apply, and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims
or to contest validity of any such claims; this section has the sole purpose of protecting the integrity
of the free software distribution system which is implemented by public license practices. Many peo-
ple have made generous contributions to the wide range of software distributed through that system
in reliance on consistent application of that system; it is up to the author/donor to decide if he or she
is willing to distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of
this License.
12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by
copyrighted interfaces, the original copyright holder who places the Library under this License may
add an explicit geographical distribution limitation excluding those countries, so that distribution is
permitted only in or among countries not thus excluded. In such case, this License incorporates the
limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new versions of the Lesser General
Public License from time to time. Such new versions will be similar in spirit to the present version, but
may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library specifies a version number of this
License which applies to it and "any later version", you have the option of following the terms and con-
ditions either of that version or of any later version published by the Free Software Foundation. If the
Library does not specify a license version number, you may choose any version ever published by the
Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs whose distribution condi-
tions are incompatible with these, write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals of preserving the free status of
all derivatives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY,
TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS
WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SER-
VICING, REPAIR OR CORRECTION.

16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPY-

DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest possible use to the public, we recom-
mend making it free software that everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the ordinary General Public
License).
To apply these terms, attach the following notices to the library. It is safest to attach them to the start
of each source file to most effectively convey the exclusion of warranty; and each file should have at
least the "copyright" line and a pointer to where the full notice is found.
You should have received a copy of the GNU Lesser General Public License along with this library; if
not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307
USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copy-
right disclaimer" for the library, if necessary. Here is a sample; alter the names:
<one line to give the library's name and a brief idea of what it does.>

even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU Lesser General Public License for more details.

packets are received. There are different codecs, with differing degrees of compression,
for instance.
Both parties involved in the telephone connection (caller/sender and recipient) must
use the same codec. This is negotiated between the sender and the recipient when
establishing a connection.
The choice of codec is a compromise between voice quality, transmission speed and the
necessary bandwidth. A high level of compression, for example, means that the band-
width required for each voice connection is low. However, it also means that the time
needed to compress/decompress the data is greater, which increases execution time for
data in the network and thus impairs voice quality. The time required increases the delay
between the sender speaking and the recipient hearing what has been said.
COLP / COLR
Connected Line Identification Presentation/Restriction
Service characteristic of a VoIP connection for outgoing calls.
COLP displays the phone number accepting the call on the calling party's display unit.
The number of the party accepting the call is different to the dialled number, e.g. if the
call is forwarded or transferred.
The called party can use COLR (Connected Line Identification Restriction) to prevent the
number from appearing on the calling party's display.
Consultation call
You are on a call. With a consultation call, you interrupt the conversation briefly to
establish a connection to another participant. If you terminate the connection to this
participant immediately, then this is a consultation call. If you switch to and fro between
the first and second participants, it is called Toggling.

D
DHCP
Dynamic Host Configuration Protocol
Internet protocol that handles the automatic assignment of IP addresses to Network
subscribers. The protocol is made available in the network by a server. A DHCP server
can be a router for example.
The phone contains a DHCP client. A router that contains a DHCP server can assign the
IP addresses for the phone automatically from a defined address block. The dynamic
assignment means that several Network subscribers can share one IP address,
although they use it alternately and not simultaneously.
With some routers you can specify that the IP address for the phone is never changed.
Displayed name
VoIP provider feature. You can specify any name that is to be shown to the other party
during a call instead of your phone number.
DMZ (Demilitarised Zone)
DMZ describes a part of a network that is outside the firewall.
A DMZ is set up, as it were, between a network you want to protect (e.g. a LAN) and a
non-secure network (e.g. the Internet). A DMZ permits unrestricted access from the
Internet to only one or a few network components, while the other network compo-
nents remain secure behind the firewall.
DNS
Domain Name System
Hierarchical system that permits the assignment of IP addresses to Domain names that
are easier to note. This assignment has to be managed by a local DNS server in each
(W)LAN. The local DNS server determines the IP address, if necessary by enquiring about
superordinate DNS servers and other local DNS servers on the Internet.
You can specify the IP address of the primary/secondary DNS server.
See also: DynDNS.
Domain name
Name of one (of several) Web server on the Internet (e.g. Siemens Home) The domain
name is assigned to the relevant IP address by DNS.
DSCP
Differentiated Service Code Point
See Quality of Service (QoS).
DSL
Digital Subscriber Line
Data transfer technology that allows Internet access with, for e.g., 1.5 Mbps over a con-
ventional telephone line. Preconditions: DSL modem and the appropriate service
offered by the Internet provider.
DSLAM
Digital Subscriber Line Access Multiplexer
The DSLAM is a switch cabinet in an exchange at which all subscriber connectors con-
verge.

Dynamic IP address
A dynamic IP address is assigned to a network component automatically via DHCP. The
dynamic IP address for a network component can change every time it registers or at
certain time intervals.
See also: Static IP address
DynDNS
Dynamic DNS
Domain names and IP addresses are realised via DNS. For Dynamic IP addresses this
service is now enhanced with "Dynamic DNS" (DynDNS). This permits the use of a net-
work component with a dynamic IP address as a Server on the Internet. DynDNS
ensures that a service can always be addressed on the Internet under the same Domain
name irrespective of the current IP address.

Electrically Eraseable Programmable Read Only Memory
Memory building block in your phone with fixed data (e.g. default and customised set-
tings) and data saved automatically (e.g. entries to the list of callers).
Ethernet network
Wired LAN.
F
Firewall
You can use a firewall to protect your network against unauthorised external access.
This involves combining various measures and technologies (hard and/or software) to
control the flow of data between a private network you wish to protect and an unpro-
tected network (e.g. the Internet).
See also: NAT.
Firmware
Device software in which basic information is saved for the functioning of a device.
A new version of the firmware can be loaded into the device's memory (firmware
update) to correct errors or update the device software.

Full duplex
Data transfer mode in which data can be sent and received at the same time.
G
G.711 a law, G.711 µ law
Standard for a Codec.
G.711 delivers a very good voice quality that corresponds to that in the ISDN fixed line.
As there is little compression, the necessary bandwidth is around 64 kbit/s per voice con-
nection, but the delay caused by coding/decoding is only 0.125 ms.
"a law" describes the European standard and "µ law" describes the North American/Jap-
anese equivalent.
G.722
Standard for a Codec.
G.722 is a broadband language codec with a bandwidth of 50 Hz to 7 kHz, a net trans-
fer rate of 64 kbit/s per language connection and integrated speech pause recognition
and comfort noise generation (silence suppression).
G.722 delivers very good voice quality. A higher sampling rate provides clearer and bet-
ter voice quality than other codecs and enables a speech tone in High Definition Sound
Performance (HDSP).
G.726
Standard for a Codec.
G.726 delivers a good voice quality. It is inferior to the quality with codec G.711 but bet-
ter than with G.729.
G.729A/B
Standard for a Codec.
The voice quality is rather lower with G.729A/B. As a result of the high level of compres-
sion, the necessary bandwidth is only around 8 kbit/s per voice connection, but the
delay is around 15 mins.
Gateway
Connects two different Networks, e.g. a router as an Internet gateway.
For phone calls from VoIP to the telephone network, a gateway has to be connected to
the IP network and the telephone network (gateway/VoIP provider). It forwards calls
from VoIP to the telephone network as required.
Gateway Provider

Router.
Instant messaging
Service that uses a client program to allow chatting in real time, i.e. to send brief mes-
sages to other subscribers on the Internet.
Internet
Global WAN. A series of protocols have been defined for exchanging data, known by the
name TCP/IP.
All Network subscribers are identifiable via their IP address. DNS assigns a Domain
name to the IP address.
Important services on the Internet include the World Wide Web (WWW), e-mail, file
transfer and discussion forums.
Internet Service Provider
Enables access to the Internet for a fee.
IP (Internet Protocol)
TCP/IP protocol on the Internet. IP is responsible for addressing subscribers in a Net-
work using IP addresses and routes data from the sender to the recipient. IP determines
the paths (routing) along which the data packets travel.
IP address
A unique address for a network component within a network based on the TCP/IP proto-
cols (e.g. LAN, Internet). On the Internet, domain names are usually assigned instead
of IP addresses. DNS assigns the corresponding IP address to the domain name.
The IP address has four parts (decimal numbers between 0 and 255) separated by full
stops (e.g. 230.94.233.2).

Version 2.1, 08.01.2007
The IP address is made up of the network number and the number of the Network sub-
scribers (e.g. phone). Depending on the Subnet mask, the front one, two or three parts
make up the network number and the rest of the IP address addresses the network com-
ponent. The network number of all the components in any one network must be iden-
tical.
IP addresses can be assigned automatically with DHCP (dynamic IP addresses) or manu-
ally (static IP addresses).

The local or private IP address is the address for a network component in the local net-
work (LAN). The network operator can assign any address he or she wants. Devices that
act as a link from a local network to the Internet (gateway or router) have a public and
a private IP address.

N
NAT
Network Address Translation
Method for converting (private) IP addresss to one or more (public) IP addresses. NAT
enables the IP addresses of Network subscriberss (e.g. VoIP telephones) in a LAN to be
concealed behind a shared IP address for the Router on the Internet.
VoIP telephones behind a NAT router cannot be reached by VoIP servers (on account of
the private IP address). In order to "get around" NAT, it is possible to use (alternatively)
ALG in the router, STUN in the VoIP telephone, or for the VoIP provider to use an Out-
bound proxy.
If an outbound proxy is made available you must allow for this in the VoIP settings for
your phone.
Network
Group of devices. Devices can be connected in either wired or wireless mode.
Networks can also differ in range and structure:
– Range: local networks (LAN) or wide-area networks (WAN)
–Structure: Infrastructure network or ad-hoc network
Network subscribers
Devices and computers that are connected to each other in a network, e.g. servers, PCs
and phones.
O
Outbound proxy
Alternative NAT control mechanism to STUN and ALG.
Outbound proxies are implemented by the VoIP provider in firewall/NAT environments
as an alternative to SIP proxy server. They control data traffic through the firewall.
Outbound proxy and STUN servers should not be used simultaneously.
See also: STUNand NAT.
P
Paging (handset search)
A base station function to locate registered handsets. The base station establishes a con-
nection to every registered handset. The handsets start to ring. Paging is activated by
briefly pressing the button on the base station and is deactivated by briefly pressing the
same button again.
PIN
Personal Identification Number
Protects against unauthorised use. When the PIN is activated a number combination has
to be entered in order to access a protected area.
You can protect your base station configuration data with a system PIN (4-digit number
combination).
Port
Data is exchanged between two applications in a Network via a port.

Port forwarding
The Internet gateway (e.g. your router) forwards data packets from the Internet that are
directed to a certain Port to the port concerned. This allows servers in the LAN to offer
services on the Internet without you needing a public IP address.
Port number
Indicates a specific application of Network subscribers. Depending on the setting in
the LAN, the port number is permanently assigned or else it is newly assigned with each
access.
The combination of IP address/Port number uniquely identifies the recipient or sender
of a data packet within a network.
Pre-dialling
See Block dialling.
Private IP address
See Public IP address.
Protocol
Describes the agreements for communicating within a Network. It contains rules for
opening, administering and closing a connection, about data formats, time frames and
possible error handling.
Proxy/Proxy server
Computer program that controls the exchange of data between Client and Server in
computer networks. If the phone sends a query to the VoIP server, the proxy acts as
a server towards the phone and as a client towards the server. A proxy is addressed via
IP address/Domain name and Port.
Public IP address
The public IP address is the address for a network component on the Internet. It is
assigned by the Internet Service Provider. Devices that act as a link from a local network
to the Internet (gateway, router) have a public and a local IP address.
See also: IP address, NAT
Q
Quality of Service (QoS)
Describes the Quality of Service in communication networks. Differentiations are made
between various Quality of Service classes.
QoS influences the flow of data packets on the Internet, e.g. by prioritising data packets,
reserving bandwidth and data packet optimisation.
In VoIP networks, QoS influences the voice quality. If the whole infrastructure (router,
network server etc.) has QoS, the voice quality is better, i.e. fewer delays, less echoing,
less crackling.

R
RAM
Random Access Memory
Memory in which you have reading and storage rights. Items such as melodies and
screen pictures are saved in the RAM after you have loaded them onto the phone via the
Web configurator.
Registrar
The registrar manages the Network subscribers current IP addresses. When you regis-
ter with your VoIP provider, your current IP address is saved on the registrar. This means
you can also be reached when on the move.
Ringback when the call is not answered
= CCNR (Completion of Calls on No Reply). If a participant does not respond when called,
a caller can arrange an automatic ringback. As soon as the destination phone has com-
pleted a call and is free again, the caller is rung back. This feature must be supported by
the exchange. The ringback request is automatically cancelled after about 2 hours
(depending on the VoIP provider).
Ringback when the number is busy
= CCBS (Completion of Calls to Busy Subscriber). If a caller hears the busy tone, he or
she can activate the ringback function. As soon as the connection is free the caller is
rung back. As soon as the caller lifts his receiver the connection is made automatically.
ROM
Read Only Memory
A type of memory that can only be read, as opposed to RAM which can be both read and
written.
Router
Routes data packets within a network and between different networks via the quickest
route. Can connect Ethernet networks and WLAN. Can be a Gateway to the Internet.
Routing
Routing is the transfer of data packets to another subscriber in your network. On its way
to the recipient, the data packets are sent from one router to the next until it reaches its
destination.
If data packets were not forwarded in this way, a network like the Internet would not be
possible. Routing connects the individual networks to this global system.
A router is a part of this system; it transfers data packets both within a local network and
from one network to the next. Transfer of data from one network to another is per-
formed on the basis of a common protocol.
RTP
Realtime Transport Protocol
Global standard for transferring audio and video data. Often used in conjunction with
UDP. In this case, RTP packets are embedded in UDP packets.
RTP port
(Local) Port that is used to send and receive voice data packets for VoIP.

S
Server
Provides a service to other Network subscribers (Clients). The term can indicate a com-
puter/PC or an application. A server is addressed via IP address/Domain name and Port.
SIP (Session Initiation Protocol)
Signalling protocol independent of voice communication. Used for establishing and
ending a call. It is also possible to define parameters for voice transmission.
SIP address
See URI.
SIP port/Local SIP port
(Local) Port which is used to send and receive SIP signalling data for VoIP.
SIP provider
See VoIP provider.
SIP proxy server
IP address of your VoIP provider's gateway server.
Static IP address
A static IP address is assigned to a network component manually during network con-
figuration. Unlike a Dynamic IP address a static (fixed) IP address never changes.
STUN
Simple Transversal of UDP over NAT
NAT control mechanism.
STUN is a data protocol for VoIP telephones. STUN replaces the private IP address in the
data packets of the VoIP telephone with the public address of the secure private net-
work. To control data transfer, a STUN server is also required on the Internet. STUN can-
not be implemented with symmetric NATs.
See also: ALG, Firewall, NAT, Outbound proxy.
Subnet
Segment of a Network.
Subnet mask
IP addresses consist of a fixed line number and a variable subscriber number. The net-
work number is identical for all Network subscriberss. The proportion of the IP address
made up of the network number is determined in the subnet mask. In the subnet mask
255.255.255.0, for e.g., the first three parts of the IP address are the network number
and the last part the subscriber number.
Symmetric NAT
A symmetric NAT assigns different external IP addresses and port numbers to the same
internal IP addresses and port numbers – depending on the external target address.

individual caller without allowing the waiting caller to screen the call.
Transfer rate
Speed at which data is transferred in the WAN or LAN. The transfer rate is measured in
data units per unit of time (Mbit/s).
Transport protocol
Controls data transport between communication partners (applications).
See also: UDP, TCP, TLS.
U
UDP
User Datagram Protocol
Transport protocol. Unlike TCP, UDP is a non session-based protocol. It does not estab-
lish a fixed connection. The data packets (datagrams) are sent as broadcast. The recipi-
ent is solely responsible for making sure the data is received. The sender is not notified
about whether it is received.
URI
Uniform Resource Identifier
Character sequence for identifying resources (e.g. e-mail recipient, http://siemens.com,
files).
On the Internet URIs are used as a uniform identification for resources. URIs are also
described as SIP addresses.
URIs can be entered in the phone as a number. By dialling a URI you can call an Internet
subscriber with VoIP equipment.
URL
Universal Resource Locator
Globally unique address of a domain on the Internet.
A URL is a subtype of URI. URLs identify a resource by its location on the Internet. For
historical reasons the term is often used as a synonym for URI.
User identification
Name/number combination for access, e.g. to your VoIP account.
