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.

The Cisco implementation of TCP header compression is an adaptation of a program developed by the University of California, Berkeley (UCB) as

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

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.

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.

Feature Overview

Cisco Unified IP Phones provide traditional telephony functionality, such as call

forwarding and transferring, redialing, speed dialing, conference calling, and

voice messaging system access. Cisco Unified IP Phones also provide a variety of

other features. For an overview of the telephony features that the Cisco Unified IP

Phone 7905G and 7912G support, see Chapter 5, “Configuring Telephony

Features.”

Like other network devices, you must configure the Cisco Unified IP Phones to

prepare them to access Cisco Unified CallManager and the rest of the IP network.

Using DHCP, you have fewer settings to modify, but you can choose to assign a

static IP if your network requires it. For instructions on configuring the network

settings on the Cisco Unified IP Phones, see Chapter 4, “Configuring Settings on

the Cisco Unified IP Phone.”

Because the Cisco Unified IP Phone is a network device, you can obtain detailed

status information about it. This information can assist you in troubleshooting

problems that users might encounter when using their IP phones. See Chapter 7,

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.

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.

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

OL-8131-01

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.

Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network

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.

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.

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.”

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.”

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 1–4 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 1–4 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.

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

configuration file is deleted from the Cisco Unified CallManager TFTP server.

The phone’s directory number remains in the Cisco Unified CallManager

database. Such a directory number is called an “unassigned DNs and can be used

for other devices. If unassigned DNs are not used by other devices, delete them

from the Cisco Unified CallManager database. You can use the Route Plan Report

to view and delete unassigned reference numbers. Refer to

Cisco Unified CallManager Administration Guide for more information.
