Two ways to customize configurations of your SIP-T48G IP phone:
zThe user interface on the IP phone.
zThe user interface in a web browser on your PC.
The hardware components keypad and LCD screen constitute the phone user
interface, which allows the user to execute all call operation tasks and basic
configuration changes directly on the phone. In addition, you can use the web user
interface to access all configuration settings. In many cases, it is possible to use either
the phone user interface and/or the web user interface interchangeably. However, in
some cases, it is only possible to use one or the other interface to operate the phone
and change settings.
2JQPG7UGT+PVGTHCEG
You can customize your phone by pressing the Menu soft key to access the phone user
interface. The Advanced option is only accessible to the administrator, and the default
administrator password is “admin” (case-sensitive). For more information on customizing
your phone with the available options from the phone user interface, refer to
Customizing Your Phone on page 25.
9GD7UGT+PVGTHCEG
In addition to the phone user interface, you can also customize your phone via web
user interface. In order to access the web user interface, you need to know the IP
address of your new phone. To obtain the IP address, press the OK key on the phone.
Enter the IP address (e.g., http://192.168.0.10 or 192.168.0.10) in the address bar of web
browser on your PC. The default administrator user name and password are both
“admin” (case-sensitive).

Basic expression syntaxes you need to know:
Syntax Description
.
The dot "." can be used as a placeholder or multiple placeholders for
any character. Example:
"12." would match "123", "1234", "12345", "12abc", etc.
x An "x" can be used as a placeholder for any character. Example:
"12x" would match "121", "122", "123", "12a", etc.
[]
The square brackets "[]" can be used as a placeholder for a single
character which matches any of a set of characters. Example:
"91[5-7]1234" would match "9151234", "9161234", "9171234", etc.
()
The parentheses "( )" can be used to group together patterns, for
instance, to logically combine two or more patterns. Example:
"([1-9])([2-7])3" would match "923", "153", "773",etc.
$
The “$” should be followed by the sequence number of a parenthesis.
The “$” plus the sequence number means the whole character or
characters placed in the parenthesis. The number directs to the right
parenthesis when there are more than one. Example:
A replace rule configuration: Prefix: "9([5-7])(.)", Replace: "5$2". When
you enter "96123" to dial out on your phone, the number will be
replaced as "5123" and then dialed out. “$2” means the characters in
the second parenthesis, that is, “123”.
4GRNCEG4WNG
You can configure one or more replace rules (at most 100) to remove the specified
string and replace it with another string. You can configure a pattern with wildcards
(refer to the expression syntax in the table above), so that any string that matches the
pattern will be replaced. This feature is convenient for you to dial out a long number. For
example, a replace rule is configured as "Prefix: 1" and "Replace: 1234567", when you try
to dial out the number “1234567”, you just need to enter “1” on the phone and then
press the Send soft key.
To add a replace rule via web user interface:
1. Click on Settings->Dial Plan->Replace Rule.
2. Enter the string (e.g., 2xx) in the Prefix field.

Hot desking originates from the definition of being the temporary physical occupant of
a work station or surface by a particular employee. A primary motivation for hot desking
is cost reduction. This feature is regularly used in places where not all the employees are
in the office at the same time, or not in the office for very long at all, which means
actual personal offices would be often vacant, consuming valuable space and
resources.
You can use hot desking on the SIP-T48G IP phone to log out of the existing accounts
and then log into a new account. As a result, many users can share the phone resource
in different time. To use this feature, you need to configure a hot desking key in

You can configure the phone to receive a Real Time Transport Protocol (RTP) stream
from the pre-configured multicast address(es) without involving SIP signaling. You can
specify up to 10 multicast addresses that the phone listens to on the network.
How the phone handles incoming multicast paging calls depends on Paging Barge
and Paging Priority Active parameters configured via web user interface.
Paging Barge
Paging barge parameter defines the priority of the voice call in progress. If the priority
of an incoming multicast paging call is lower than that of the active call, it will be
ignored automatically. If Disabled is selected from the pull-down list of Paging Barge,
the voice call in progress takes precedence over all incoming multicast paging calls.
Valid values in the Paging Barge field:
z1 to 10: Define the priority of the active call, 1 with the highest priority, 10 with the
lowest.
zDisabled: The voice call in progress shall take precedence over all incoming paging
calls.
Paging Priority Active
Paging priority active parameter decides how the phone handles incoming multicast
paging calls when there is already a multicast paging call on the phone. If enabled,
the phone will ignore incoming multicast paging calls with lower priorities, otherwise,
the phone will answer incoming multicast paging calls automatically and place the
previous multicast paging call on hold. If disabled, the phone will automatically ignore
all incoming multicast paging calls.
To configure multicast listening addresses via web user interface:
1. Click on Directory->Multicast IP.
2. Select the desired value from the pull-down list of Paging Barge.
3. Select the desired value from the pull-down list of Paging Priority Active.
4. Enter the multicast IP address(es) and port number (e.g., 224.5.6.20:10008) which
the phone listens for incoming RTP multicast in the Listening Address field.
Multicast RTP is one way only from sender to the multicast address(es) (receiver). For
outgoing RTP multicasts, all other existing calls on the phone will be placed on hold.

zEnsure that the Ethernet cable is plugged into the Internet port on the phone and the
Ethernet cable is not loose.
zEnsure that the switch or hub in your network is operational.
Why doesn’t the phone display time and date correctly?
