THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT
NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT
ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR
THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION
PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO
LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate
radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television
reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in
part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation.
However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class
A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct
any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco
equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by
using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television
or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4
service requests. (S3 and S4 service requests are those in which your network is
minimally impaired or for which you require product information.) After you
describe your situation, the TAC Service Request Tool provides recommended
solutions. If your issue is not resolved using the recommended resources, your
service request is assigned to a Cisco engineer. The TAC Service Request Tool is
located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the
Cisco TAC by telephone. (S1 or S2 service requests are those in which your
production network is down or severely degraded.) Cisco engineers are assigned
immediately to S1 and S2 service requests to help keep your business operations
running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has
established severity definitions.
Severity 1 (S1)—Your network is “down,” or there is a critical impact to your
business operations. You and Cisco will commit all necessary resources around
the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or
significant aspects of your business operation are negatively affected by
inadequate performance of Cisco products. You and Cisco will commit full-time
resources during normal business hours to resolve the situation.
Preface

Severity 3 (S3)—Operational performance of your network is impaired, but most
business operations remain functional. You and Cisco will commit resources
during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product
capabilities, installation, or configuration. There is little or no effect on your
business operations.

An Overview of the Cisco Unified IP
Phone
The Cisco Unified IP Phone provides voice communication over an Internet
Protocol (IP) network. It functions much like a traditional analog telephone,
allowing you to place and receive phone calls and to access features such as mute,
hold, transfer, and speed dial. In addition, because the phone is connected to your
data network, it offers enhanced IP telephony features, including access to
network information and customizeable features.
This manual describes the Cisco Unified IP Phone 7905G and 7912G. The Cisco
Unified IP Phone 7905G and 7912G include softkeys and an LCD screen. The
Cisco Unified IP Phone 7912G adds an internal Ethernet switch.
These phones encode G.711a, G.711u, G.729a, G.729ab, and decode all variants
of G.711 and G.729.
A Cisco Unified IP Phone must be configured and managed like other network
devices.

Caution Using a cell, mobile, or GSM phone, or two-way radio in close proximity to a
Cisco Unified IP Phone might cause interference. For more information, refer to
the manufacturer’s documentation of the interfering device.
Understanding the Cisco Unified IP Phone 7905G and
7912G
The Cisco Unified IP Phone 7905G and 7912G are basic IP phones that address
the voice communication needs of employees who engage in low to medium
telephone use. The phones provide a pixel display and dynamic softkeys for easy
access to a core set of business features. They support a maximum of two calls
and one directory number, and inline power for receiving power through and
Ethernet connection. The Cisco Unified IP Phone 7912G includes an integrated
10/100 Ethernet switch for connecting a PC.
Note The hardware updated version of the Cisco Unified IP Phone 7912G
(CP-7912G-A) offers IEEE 802.1Q VLAN-based switching of packets received
from the attached PC and from the network port (upstream switch). This allows
the phone to operate more efficiently in networks which may be subject to large
amounts of broadcast, multicast and/or unknown unicast traffic.
Figure 1-1 shows the main components of the Cisco Unified IP Phone 7905G and
7912G.

Chapter 1 An Overview of the Cisco Unified IP Phone
What Networking Protocols Are Used?
What Networking Protocols Are Used?
Cisco Unified IP Phones support several industry-standard and Cisco networking
protocols for voice communication. Table 1-1 provides an overview of the
networking protocols that the Cisco Unified IP Phone 7905G and 7912G support.
Table 1-1 Supported Networking Protocols on the Cisco Unified IP Phone
Networking Protocol Purpose Usage Notes
Cisco Discovery
Protocol (CDP) CDP is a device-discovery protocol
that runs on all Cisco-manufactured
equipment.
Using CDP, a device can advertise its
existence to other devices and receive
information about other devices in
the network.
The Cisco Unified IP Phone uses
CDP to communicate information
such as auxiliary VLAN ID, per-port
power management details, and
Quality of Service (QoS) configuration
information with the Cisco Catalyst
switch.
Dynamic Host
Configuration Protocol
(DHCP)
DHCP dynamically allocates and
assigns an IP address to network
devices.
DHCP enables you to connect an
IP phone into the network and have
the phone become operational
without you needing to manually
assign an IP address or configure
additional network parameters.
DHCP is enabled by default. If
disabled, you must manually
configure the IP address, subnet
mask, gateway, and an TFTP server
on each phone locally.
Cisco recommends that you use
DHCP custom option 150. With this
method, you configure the TFTP
server IP address as the option value.
For additional supported DCHP
configurations, refer to Cisco
Unified CallManager System Guide.
HyperText Transfer
Protocol (HTTP)
HTTP is the standard way of
transferring information and moving
documents across the Internet and the
World Wide Web.
The Cisco Unified IP Phones use
HTTP for the XML services and for
troubleshooting purposes.
Chapter 1 An Overview of the Cisco Unified IP Phone
What Networking Protocols Are Used?
1-6
Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.0 (SIP), Cisco Unified IP Phones
OL-8131-01
Internet Protocol (IP) IP is a messaging protocol that
addresses and sends packets across
the network.
To communicate using IP, network
devices must have an assigned IP
address, subnet, and gateway.
IP addresses, subnets, and gateways
identifications are automatically
assigned if you are using the
Cisco Unified IP Phone with
Dynamic Host Configuration
Protocol (DHCP). If you are not
using DHCP, you must manually
assign these properties to each phone
locally.
Real-Time Transport
(RTP) RTP is a standard for transporting
real-time data, such as interactive
voice and video, over data networks.
Cisco Unified IP Phones use the RTP
protocol to send and receive
real-time voice traffic from other
phones and gateways.
Session Description
Protocol (SDP) SDP is the portion of the SIP that
determines which parameters are
available during a connection
between two endpoints. Conferences
are established using only the SDP
capabilities that are supported by all
endpoints in the conference.
SDP capabilities, such as codec
types, DTMF detection and comfort
noise, are normally configured on a
global basis by the Cisco Unified
CallManager or the Media Gateway
in operation. Some SIP endpoints
may allow these parameters to be
configured on the endpoint itself.
Transmission Control
Protocol (TCP) TCP is a a connection-oriented
transport protocol. Cisco Unified IP Phones use TCP to
connect to
Cisco Unified CallManager.
Trivial File Transfer
Protocol (TFTP) TFTP allows you to transfer files
over the network.
On the Cisco Unified IP Phone,
TFTP enables you to obtain a
configuration file specific to the
phone type.
TFTP requires a TFTP server in your
network, which can be automatically
identified from the DHCP server. If
more than one TFTP server is
running in your network, you must
manually assign a TFTP server to
each phone locally.

traditional telephony features, the Cisco Unified IP Phones include features that
enable you to administer and monitor the phone as a network device.
This section includes the following topics:
Feature Overview, page 1-8
Configuring Telephony Features, page 1-8
Session Initiation
Protocol (SIP) SIP is the Internet Engineering task
Force (IETF) standard for
multimedia conferencing over IP. SIP
is an ASCII-based, application-layer
control protocol that can be used to
establish, maintain, and terminate
calls between two or more endpoints.
The
Cisco Unified IP Phone 7905G/7912
G support UDP-based SIP signalling.
Like other VoIP protocols, SIP is
designed to address the functions of
signaling and session management
within a packet telephony network.
Signaling allows call information to
be carried across network
boundaries. Session management
provides the ability to control the
attributes of an end-to-end call.
User Datagram Protocol
(UDP) UDP is a connectionless messaging
protocol for delivery of data packets. Cisco Unified IP Phones receive and
process UDP messages.

Understanding How the Cisco Unified IP Phone Interacts with
Cisco Unified CallManager
Cisco Unified CallManager is an open and industry-standard call processing
system. Cisco Unified CallManager software runs on a Windows 2000 or Linux
server and sets up and tears down calls between phones, integrating traditional
PBX functionality with the corporate IP network. Cisco Unified CallManager
manages the components of the IP telephony system—the phones, access
gateways, and the resources necessary for such features as call conferencing and
route planning.
For information about configuring Cisco Unified CallManager to work with the
IP devices described in this chapter, refer to Cisco Unified CallManager
Administration Guide and Cisco Unified CallManager System Guide.

Understanding How the Cisco Unified IP Phone Interacts with the
Cisco Catalyst Family of Switches
The Cisco Unified IP Phone 7912G has an internal Ethernet switch, enabling it to
switch incoming traffic to the phone, to the access port, or to the network port.
The Cisco Unified IP Phone 7905G do not include an internal Ethernet switch or
an access port.
If a computer is connected to the access port, the computer and the phone share
the same physical link to the switch and share the same port on the switch. This
shared physical link has the following implications for the VLAN configuration
on the network:
The current VLANs may be configured on an IP subnet basis. However,
additional IP addresses may not be available to assign the phone to the same
subnet as other devices connected to the same port.
Data traffic present on the VLAN supporting phones may reduce the quality
of Voice-over-IP traffic.
You can resolve these issues by isolating the voice traffic onto a separate VLAN
on each of the ports connected to a phone. The switch port configured for
connecting a phone would have separate VLANs configured for carrying:
Voice traffic to and from the IP phone (auxiliary VLAN)
Data traffic to and from the PC connected to the switch through the access
port of the IP phone (native VLAN)
Isolating the phones on a separate, auxiliary VLAN increases the quality of the
voice traffic and allows a large number of phones to be added to an existing
network where there are not enough IP addresses.
For more information, refer to the documentation included with the
Cisco Catalyst switch.

Understanding the Phone Startup Process
When connecting to the VoIP network, the Cisco Unified IP Phone goes through
a standard startup process composed of the steps described in Table 2-1.
Depending on your specific network configuration, not all of these steps may
occur on your Cisco Unified IP Phone.
Table 2-1 Cisco Unified IP Phone Startup Process
Step Configuration Related Topics
1. Obtaining Power
from the Switch You can connect the Cisco Unified IP Phone to a
Cisco Catalyst switch with one of the modules that
provides power to the phone (WS-X6348-RJ45V).
See the “Providing Power to the Cisco Unified IP
Phone” section on page 2-9 for details.
If you use this optional configuration, the phone
receives phantom power and powers up when you
connect the Cisco Unified IP Phone to the switch.
The phone then sends Cisco Discovery Protocol
(CDP) notifications to the switch indicating that it
is ready to receive CDP packets and indicating the
power requirement for the phone. The switch
allocates power and sends it over the network
cable.

Phone Startup
Process, page 2-4
Providing Power to
the Cisco Unified
IP Phone, page 2-9
Resolving Startup
Problems, page 7-2
2. Loading the Stored
Phone Image The Cisco Unified IP Phone has non-volatile Flash
memory in which it stores firmware images and
user-defined preferences. At startup, the phone
runs a bootstrap loader that loads a phone image
stored in Flash memory. Using this image, the
phone initializes its software and hardware.

Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network
Understanding the Phone Startup Process
3. Configuring VLAN If the Cisco Unified IP Phone is connected to a
Cisco Catalyst switch, the switch next informs the
phone of the voice VLAN defined on the switch.
The phone needs to know its VLAN membership
before it can proceed with the Dynamic Host
Configuration Protocol (DHCP) request for an IP
address.

Descriptions”
section on
page 4-10
“Resolving Startup
Problems” section
on page 7-2
4. Obtaining an IP
Address If the Cisco Unified IP Phone is using DHCP to
obtain an IP address, the phone queries the DHCP
server to obtain one. If you are not using DHCP in
your network, you must assign a static IP address
to each phone locally.

5. Accessing a TFTP
Server In addition to assigning an IP address, the DHCP
server directs the Cisco Unified IP Phone to a
TFTP Server. If the phone has a statically defined
IP address, you must configure the TFTP server
locally on the phone; the phone then contacts the
TFTP server directly.

6. Requesting the
Configuration File and
the Profile File
The TFTP server has configuration files and
profile files. A configuration file includes
parameters for connecting to
Cisco Unified CallManager and information about
which image load a phone should be running. A
profile file contains various parameters and values
for phone and network settings.
“Understanding
Phone
Configuration Files
and Profile Files”
section on page 2-8
“Resolving Startup
Problems” section
on page 7-2
7. Contacting
Cisco Unified CallMan
ager
The configuration file defines how the
Cisco Unified IP Phone communicates with
Cisco Unified CallManager. After obtaining the
file from the TFTP server, the phone attempts to
make a TCP connection to the highest priority
Cisco Unified CallManager on the list.
If the phone was manually added to the database,
Cisco Unified CallManager identifies the phone.
If the phone was not manually added to the
database and auto-registration is enabled in
Cisco Unified CallManager, the phone attempts to
auto-register itself in the
Cisco Unified CallManager database.
Cisco Unified CallManager informs devices,
using the following configuration file formats, of
their load ID. Note that mac is the hexadecimal
representation of the MAC address of the phone:
For
Cisco Unified IP Phone 7905G—ld<mac> or
ld<mac>.x
For
Cisco Unified IP Phone 7912G—gk<mac> or
gk<mac>.x

Understanding Phone Configuration Files and Profile
Files
Configuration files for a phone are stored on the TFTP server and define
parameters for connecting to Cisco Unified CallManager. In general, any time
you make a change in Cisco Unified CallManager that requires the phone to be
reset, a change is made to the phone’s configuration file automatically.
Configuration files also contain information about which image load the phone
should be running. If this image load differs from the one currently loaded on a
phone, the phone contacts the TFTP server to request the new image file.
The phone first requests the following configuration file, where mac is the
hexadecimal representation of the MAC address of the phone:
For Cisco Unified IP Phone 7905G—ld<mac> or ld<mac>.x
For Cisco Unified IP Phone 7912G—gk<mac> or gk<mac>.x
If the phone cannot find a file of this naming convention, the phone then looks for
the following file:
For Cisco Unified IP Phone 7905G—lddefault.cfg or lddefault.cfg.x
For Cisco Unified IP Phone 7912G—gkdefault.cfg or gkdefault.cfg.x
After the phone finds one of the profile files, or if it cannot find a profile file, it
continues with its startup process.
Note For information on using your phone in a secure Cisco Unified CallManager
environment, see the “Configuring the Encryption Key” section on page 4-7.

Providing Power to the Cisco Unified IP Phone
You can power a Cisco Unified IP Phone by the following sources:
External power—optional Cisco AC adapter and power cord for connecting
to a standard wall receptacle.
Inline power—inline power provider to the Cisco Unified IP Phone when
connected to a Cisco Catalyst switch capable of providing inline power.
Note Only the network port supports inline power from the Cisco Catalyst
switches.
WS-X6348-RJ45V 10/100 switching module—Inline power provider to the
Cisco Unified IP Phone when connected to a Catalyst 6000 family
10/100BaseTX switching module.
This module sends power on pins 1 & 2 and 3 & 6, which are also used to
transmit Ethernet signals. Before the switch sends power, it tests for the
presence of a Cisco Unified IP Phone, avoiding damage to other Ethernet
devices.
Note Only the network port supports inline power from the Cisco Catalyst
switches.
WS-PWR-PANEL—power patch panel that allows the Cisco Unified IP
Phone to be connected to existing Catalyst 4000, 5000, and 6000 family
10/100BaseTX switching modules.
This module sends power on pins 4, 5, 7, & 8, which are not used for Ethernet
signaling. The power patch panel also attempts to verify that the attached
device is a Cisco Unified IP Phone before providing power.

Power Outage
Your accessibility to emergency service through the phone is dependent on the
phone being powered. If there is an interruption in the power supply, Service and
Emergency Calling Service dialing will not function until power is restored. In the
case of a power failure or disruption, you may need to reset or reconfigure
equipment before using the Service or Emergency Calling Service dialing.
Power Source Design
The phone and switch automatically determine which power source the phone
uses. If the power has to be switched to a different source, the phone user will
experience different results based on which power source is being used by the
phone.
Use the following information to choose a power source for the phone:
If you plug a phone into the optional power supply before plugging it into the
network, the phone is powered by the power supply.
If you then unplug the phone from the power supply, the phone resets. If the
switch port is configured for 10/100 Mbps, the switch recognizes the loss of
power and brings the phone back up.
If the switch port is configured for 10 Mbps only, then you must unplug the
network connection and plug it back into the phone for the switch to
recognize the phone’s loss of power.
If, however, you plugged the network connection into the phone before you
plugged in the power cord, the phone receives power through the switch, and
unplugging the power cord will not bring down the phone. If the switch
reboots, the phone will then be powered by the power cord.

Redundancy Feature
For redundancy, you can use the Cisco AC adapter even if you are using inline
power from the Cisco Catalyst switches. The Cisco Unified IP Phone can share
the power load being used from the inline power and external power source. If
either the inline power or the external power goes down, the phone can switch
entirely to the other power source.
To use this redundancy feature, follow these steps:
Procedure
Step 1 Set the inline power mode to auto on the Cisco Catalyst switch.
Step 2 Connect the unpowered Cisco Unified IP Phone to the network.
Step 3 Connect the external power supply to the phone after the phone powers up.

Table 2-3 provides an overview of these methods for adding phones to the
Cisco Unified CallManager database.
Adding Phones with Auto-Registration
You can add phones with auto-registration without first gathering MAC addresses
from the phones.
When auto-registration is enabled, Cisco Unified CallManager begins the
automatic startup process to obtain a directory number. During auto-registration,
Cisco Unified CallManager automatically assigns the next available sequential
directory number to the phone.
When you use this method, Cisco Unified CallManager automatically assigns
directory numbers to new phones as they register with Cisco Unified
CallManager.

port is labelled “10/100SW” and the access port is labeled “10/100PC.” The back
of the Cisco Unified IP Phone 7905G has one RJ-45 network port.
The two ports on the Cisco Unified IP Phone 7912G each support 10/100 Mbps
half- or full-duplex connections to external devices. The speed and connection
type are set through auto-negotiation. The single port on the Cisco Unified IP
Phone 7905G supports 10 Mbps half-duplex connections to external devices. You
can use either Category 3 or 5 cabling for 10-Mbps connections, but you must use
Category 5 for 100 Mbps connections.
Use the network port to connect the phone to the network. You must use a
straight-through cable on this port. The phone can also obtain inline power from
the Cisco Catalyst switch over this connection. See the “Providing Power to the
Cisco Unified IP Phone” section on page 2-9 for details.
Use the access port to connect a network device, such as a computer, to the phone.
You must use a straight-through cable on this port.
See Figure 3-1 for the connection ports available on the back of the
Cisco Unified IP Phone 7905G. See Figure 3-2 for the connection ports available

Configuring IP Settings
Use these guidelines when manually configuring the IP settings:
You can use 0.0.0.0 for the subnet mask only if the default gateway is also
0.0.0.0.
Ensure the TFTP server has an IP address.
Ensure the default gateway IP address is on the same subnet as the host IP
address.
Note Procedures involved in configuring IP settings or TFTP parameters cannot be
completed when DHCP is enabled in your network.
Configuring the Encryption Key
Cisco Unified Call Manager can operate in secure or non-secure mode. When
operating in secure mode, Cisco Unified Call Manager generates encrypted
configuration files that can be decrypted only with the same encryption key.
If you are operating your phone in a secure environment, you must manually
configure the encryption key that the phone will use to decrypt the configuration
file downloaded from Cisco Unified Call Manager. You may configure the
encryption key by using either the LCD screen on the phone or by using the Phone
Configuration Web page.
The instructions in the following encryption-related sections assume a network
environment in which a DHCP server provides the applicable TFTP IP address,
and the Cisco Unified IP Phone has been pre-configured on the
Cisco Unified CallManager to run SIP.

Resolving Startup Problems
After installing a Cisco Unified IP Phone on your network and adding it to
Cisco Unified CallManager, the phone should start up as described in the
“Verifying the Phone Startup Process” section on page 3-11. If the phone does not
start up properly, see the following sections for troubleshooting information:
Symptom: The Cisco Unified IP Phone Does Not Go Through its Normal
Start Up Process, page 7-2
Symptom: The Cisco Unified IP Phone Does Not Register with Cisco
Unified CallManager, page 7-3
Cisco Unified IP Phone Resets Unexpectedly, page 7-8
Note Any procedures that refer to an LCD screen display problem apply only to the
Cisco Unified IP Phone 7905G and 7912G.
Symptom: The Cisco Unified IP Phone Does Not Go Through its
Normal Start Up Process
When you connect a Cisco Unified IP Phone into the network port, the phone
should go through its normal startup process and the LCD screen should display
information. If the phone does not go through the startup process, the cause may
be faulty cables, bad connections, network outages, lack of power, and so on. Or,
the phone may not be functional.
To determine whether the phone is functional, follow these suggestions to
systematically eliminate these other potential problems:
1. Verify that the network port is functional:
Exchange the Ethernet cables with cables that you know are functional.
Disconnect a functioning Cisco Unified IP Phone from another port and
connect it to this network port to verify that the port is active.
Connect the Cisco Unified IP Phone that will not start up to a different
network port that is known to be good.
Connect the Cisco Unified IP Phone that will not start up directly to the
port on the switch, eliminating the patch panel connection in the office.

Chapter 7 Troubleshooting the Cisco Unified IP Phone
Resolving Startup Problems
2. Verify that the phone is receiving power:
Verify that the electrical outlet is functional.
If you are using in-line power, try using the external power supply
instead.
If you are using the external power supply, switch with a unit that you
know to be functional.
If, after attempting these solutions, the phone still does not start up, contact a
Cisco technical support representative for additional assistance.
Symptom: The Cisco Unified IP Phone Does Not Register with
Cisco Unified CallManager
If a phone proceeds past the first stage (LED buttons flashing on and off), and, on
a Cisco Unified IP Phone 7905G and 7912G, continues to cycle through the
messages displaying on the LCD screen, the phone is not starting up properly. The
phone cannot successfully start up unless it is connected to the Ethernet network
and it has registered with a Cisco Unified CallManager server.

Registering the Phone with Cisco Unified CallManager
A Cisco Unified IP Phone can register with a Cisco Unified CallManager server
only if the phone has been added to the server or if auto-registration for SIP is
enabled. Review the information and procedures in the Adding Phones to the
Cisco Unified CallManager Database” section on page 2-12 to ensure that the
phone has been added to the Cisco Unified CallManager database.
To verify that the phone is in the Cisco Unified CallManager database, choose
Device > Phone > Find from Cisco Unified CallManager Administration to
search for the phone based on its MAC Address. (To determine the MAC address
of a phone, see the “Determining the MAC Address of a Cisco Unified IP Phone”
section on page 2-12.)
If the phone is already in the Cisco Unified CallManager database, its
configuration file may be damaged. See the “Creating a New Configuration File”
section on page 7-7 for assistance.
Checking Network Connectivity
If the network is down between the phone and the TFTP server or
Cisco Unified CallManager, the phone cannot start up properly. Ensure that the
network is currently running.
Verifying TFTP Server Settings
The Cisco Unified IP Phone uses the TFTP server setting to identify the primary
TFTP server used by the phone. If this setting is incorrect, the Cisco Unified IP
Phone may continually cycle while attempting to contact the identified TFTP
Server.
If you have assigned a static IP address to the phone, you must manually enter this
setting.
If you are using DHCP, the phone obtains the address for the TFTP server from
the DHCP server. Check the IP address configured in Option 150.
You can also enable the phone to use an alternate TFTP server. Such a setting is
particularly useful if the phone was recently moved from one location to another.
For information about determining and changing TFTP server settings, see
Chapter 4, “Configuring Settings on the Cisco Unified IP Phone,” or
Appendix A, “Reference List of Parameters.”

Chapter 7 Troubleshooting the Cisco Unified IP Phone
Resolving Startup Problems
Verifying IP Addressing and Routing
You should verify the IP addressing and routing settings for the Cisco Unified IP
Phone. If you are using DHCP, the DHCP server should provide these values. If
you have assigned a static IP address to the phone, you must enter these values
manually.
Check for the following problems:
DHCP Server—If you have assigned a static IP address to the phone, you do
not need to enter a value for the DHCP Server option. However, if you are
using a DHCP server, this option must have a value. If it does not, check your
IP routing and VLAN configuration. Refer to Troubleshooting Switch Port
Problems, available at this URL:
http://www.cisco.com/warp/customer/473/53.shtml
IP Address, Subnet Mask, Default Router—If you have assigned a static IP
address to the phone, you must manually enter settings for these options. See
Table 4-2 on page 4-19.
If you are using DHCP, check the IP addresses distributed by your DHCP server.
Refer to Understanding and Troubleshooting DHCP in Catalyst Switch or
Enterprise Networks, available at this URL:
http://www.cisco.com/warp/customer/473/100.html#41
For information about determining and changing IP addressing and routing
settings, see Chapter 4, “Configuring Settings on the Cisco Unified IP Phone,” or
Appendix A, “Reference List of Parameters.”
Verifying DNS Settings
If you are using a fully qualified domain name (FQDN) to refer to the TFTP server
or to Cisco Unified CallManager, you must ensure that you have specified a DNS
server. You should also verify that there is a CNAME entry in the DNS server for
the TFTP server and for the Cisco Unified CallManager system.
For information about determining and changing DNS settings, see Chapter 4,
“Configuring Settings on the Cisco Unified IP Phone,” or Appendix A,
“Reference List of Parameters.”

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.0 (SIP), Cisco Unified IP Phones
OL-8131-01
Verifying Cisco Unified CallManager Settings
The Cisco Unified IP Phone attempts to open a TCP connection to all the
Cisco Unified CallManager servers that are part of the assigned
Cisco Unified CallManager group. Take one of these actions to verify
Cisco Unified CallManager settings:
On the Cisco Unified IP Phone 7905G or 7912G, choose Settings > SIP
Configuration and look at the SIP Proxy 14 options. (See Chapter 4,
“Configuring Settings on the Cisco Unified IP Phone.”)
On any phone model, display the Network Configuration area of the
Cisco Unified IP Phone web page and look at the SIP Proxy 14 options.
(See Appendix A, “Reference List of Parameters.”)
If none of the Cisco Unified CallManager options contain IP addresses or show
Active or Standby, the phone is not properly registered with
Cisco Unified CallManager. See the “Registering the Phone with Cisco
Unified CallManager” section on page 7-4 for tips on resolving this problem.
Cisco Unified CallManager and TFTP Services Are Not Running
If the Cisco Unified CallManager or TFTP services are not running, phones may
not be able to start up properly. However, in such situations, it is likely that you
are experiencing a system-wide failure and that other phones and devices are
unable to start up properly.
If the Cisco Unified CallManager service is not running, all devices on the
network that rely on it to make phone calls will be affected. If the TFTP service
is not running, many devices will not be able to start up successfully.
To determine the status of a service, perform the following steps:
Procedure
Step 1 From Cisco Unified CallManager Administration, choose Cisco CallManager
Serviceability from the Navigation pull-down menu located in the upper-right
portion of the main administration screen.
Step 2 Choose Tools > Control Center—Feature Services.

Chapter 7 Troubleshooting the Cisco Unified IP Phone
Resolving Startup Problems
Step 3 From the Servers pull-down menu, choose the primary
Cisco Unified CallManager server.
The page displays the service names for the server that you chose, the status of
the services, and a service control panel to stop or start a service.
Step 4 If a service has stopped, click the service radio button and then click the Start
button.
Creating a New Configuration File
If you continue to have problems with a particular phone that other suggestions in
this chapter do not resolve, the configuration file might be corrupted.
To create a new configuration file, follow these steps:
Procedure
Step 1 From Cisco Unified CallManager Administration, select Device > Phone > Find
to locate the phone experiencing problems.
Step 2 Check the box corresponding to the phone, then click Delete Selected to remove
the phone from the Cisco Unified CallManager database.
Step 3 Add the phone back to the Cisco Unified CallManager database. See the Adding
Phones to the Cisco Unified CallManager Database” section on page 2-12 for
details.
Step 4 Power cycle the phone.
Note When you remove a phone from the Cisco Unified CallManager database, its
