Understanding the SIP Protocol

Session Initiation Protocol (SIP) is the Internet Engineering Task Force (IETF)

standard for multimedia conferencing over IP. SIP is an ASCII-based,

application-layer control protocol (defined in RFC 3261) that can be used to

establish, maintain, and terminate calls between two or more endpoints.

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.

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

you want a phone to use a TFTP

server other than the one specified by

the DHCP server, you must manually

assign TFTP server from the

Network Configuration menu on the

phone.

User Datagram Protocol

(UDP)

UDP is a connectionless messaging

protocol for delivery of data packets.

Cisco Unified IP Phones transmit and

receive RTP streams, which utilize

UDP.

What Features are Supported on the Cisco

Unified IP Phones 7970G/7971G-GE?

The Cisco Unified IP Phone functions much like a digital business phone,

allowing you to place and receive telephone calls. In addition to traditional

telephony features, the Cisco Unified IP Phone includes features that enable you

to administer and monitor the phone as a network device.

This section covers the following topics:

•Feature Overview, page 1-9

•Configuring Telephony Features, page 1-10

•Configuring Network Parameters Using the Cisco Unified IP Phone,

page 1-11

•Providing Users with Feature Information, page 1-11

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 supports, see the “Telephony Features Available for the

Phone” section on page 5-2.

As with other network devices, you must configure Cisco Unified IP Phones to

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

By using DHCP, you have fewer settings to configure on a phone, but can

manually configure an IP address, TFTP server, and subnet mask 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.”

The Cisco Unified IP Phone can interact with other services and devices on your

IP network to provide enhanced functionality. For example, you can integrate the

Cisco Unified IP Phones with the corporate Lightweight Directory Access

Protocol 3 (LDAP3) standard directory to enable users to search for co-workers

contact information directly from their IP phones. You can also use XML to

enable users to access information such as weather, stocks, quote of the day, and

other web-based information. For information about configuring such services,

see the “Configuring Corporate Directories and Personal Directories” section on

page 5-13 and the “Setting Up Services” section on page 5-16.

Finally, because the Cisco Unified IP Phone is a network device, you can obtain

detailed status information from it directly. This information can assist you with

troubleshooting any problems users might encounter when using their IP phones.

See Chapter 7, “Viewing Model Information, Status, and Statistics on the Cisco

Unified IP Phone,” for more information.

OL-11524-01

Understanding Security Features for Cisco Unified IP

Phones

Implementing security in the Cisco Unified CallManager system prevents identity

theft of the phone and Cisco Unified CallManager server, prevents data

tampering, and prevents call signaling and media stream tampering.

To alleviate these threats, the Cisco IP telephony network establishes and

maintains authenticated and encrypted communication streams between a phone

and the server, digitally signs files before they are transferred to a phone, and

encrypts media streams and call signaling between Cisco Unified IP phones.

The Cisco Unified IP Phones 7970G/7971G-GE (SIP) use the SIP Phone security

profile, which defines whether the device is nonsecure, authenticated, or

encrypted. For information on applying the security profile to the phone, refer to

the Cisco Unified CallManager Security Guide.

If you configure security-related settings in Cisco Unified CallManager

Administration, the phone configuration file will contain sensitive information.

To ensure the privacy of a configuration file, you must configure it for encryption.

For detailed information, refer to the “Configuring Encrypted Phone

Configuration Files” chapter in Cisco Unified CallManager Security Guide.

Table 1-2 shows where you can find additional information about security in this

and other documents.

Understanding Security Features for Cisco Unified IP Phones

Table 1-3 Overview of Security Features

Feature Description

Image authentication Signed binary files (with the extension .sbn) prevent tampering with

the firmware image before it is loaded on a phone. Tampering with

the image causes a phone to fail the authentication process and

reject the new image.

Customer-site certificate

installation

Each Cisco Unified IP Phone requires a unique certificate for device

authentication. Phones include a manufacturing installed

certificate, but for additional security, you can specify in Cisco

Unified CallManager Administration that a certificate be installed

by using the CAPF. Alternatively, you can initiate the installation

of an LSC from the Security Configuration menu on the phone.

Device authentication Occurs between the Cisco Unified CallManager server and the

phone when each entity accepts the certificate of the other entity.

Determines whether a secure connection between the phone and a

Cisco Unified CallManager should occur, and, if necessary, creates

a secure signaling path between the entities using TLS protocol.

Cisco Unified CallManager will not register phones unless they can

be authenticated by the Cisco Unified CallManager.

File authentication Validates digitally-signed files that the phone downloads. The

phone validates the signature to make sure that file tampering did

not occur after the file creation. Files that fail authentication are not

written to Flash memory on the phone. The phone rejects such files

without further processing.

Signaling Authentication Uses the TLS protocol to validate that no tampering has occurred to

signaling packets during transmission.

Manufacturing installed

certificate

Each Cisco Unified IP Phone contains a unique manufacturing

installed certificate (MIC), which is used for device authentication.

The MIC is a permanent unique proof of identity for the phone, and

allows Cisco Unified CallManager to authenticate the phone.

Media encryption Uses SRTP to ensure that the media streams between supported

devices proves secure and that only the intended device receives

and reads the data. Includes creating a media master key pair for the

devices, delivering the keys to the devices, and securing the

delivery of the keys while the keys are in transport.

OL-11524-01

Signaling Encryption Ensures that all SIP signaling messages that are sent between the

device and the Cisco Unified CallManager server are encrypted.

CAPF (Certificate Authority

Proxy Function)

Implements parts of the certificate generation procedure that are too

processing-intensive for the phone, and it interacts with the phone

for key generation and certificate installation. The CAPF can be

configured to request certificates from customer-specified

certificate authorities on behalf of the phone, or it can be configured

to generate certificates locally.

Security Profiles Defines whether the phone is nonsecure, authenticated, or

encrypted.

Encrypted Configuration files Enables privacy of phone configuration files.

Optional disabling of the web

server functionality for a phone

You can prevent access to a phone’s web page, which displays a

variety of operational statistics for the phone.

Phone hardening •Additional security options, which you control from Cisco

Unified CallManager Administration:

–

Disabling PC port

–

Disabling Gratuitous ARP

–

Disabling PC Voice VLAN access

–

Disabling access to the Setting menus, or providing

restricted access that allows access to the User Preferences

menu and saving volume changes only

Disabling access to web pages for a phone.

Note You can view current settings for the PC Port Disabled,

GARP Enabled, and Voice VLAN enabled options by

looking at the phone’s Security Configuration menu. For

more information, see the “Device Configuration Menu”

section on page 4-15.

802.1X Authentication The Cisco Unified IP Phone can use 802.1X authentication to

request and gain access to the network. See the “Supporting 802.1X

Authentication on Cisco Unified IP Phones” section on page 1-18

for more information.

Identifying Encrypted and Authenticated Phone Calls

When security is implemented for a phone, you can identify authenticated or

encrypted phone calls by icons on the LCD screen on the phone.

In an authenticated call, all devices participating in the establishment of the call

are authenticated by the Cisco Unified CallManager. When a call in progress is

authenticated end-to-end, the call progress icon to the right of the call duration

timer in the phone LCD screen changes to the following icon:

OL-11524-01

In an encrypted call, all devices participating in the establishment of the call are

authenticated by the Cisco Unified CallManager. In addition, call signaling and

media streams are encrypted. An encrypted call offers the highest level of

security, providing integrity and privacy to the call. When a call in progress is

being encrypted, the call progress icon to the right of the call duration timer in the

phone LCD screen changes to the following icon:

Note If the call is routed through non-IP call legs, for example, H.323 or PSTN, the call

will be nonsecure even though it is encrypted within the IP network and has a lock

icon associated with it.

Understanding Phone Configuration 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 required load files.

(These files are digitally signed to ensure the authenticity of the files’ source.)

In addition, if the device security mode in the configuration file is set to

Authenticated and the CTL file on the phone has a valid certificate for

Cisco Unified CallManager, the phone establishes a TLS connection to

Cisco Unified CallManager. Otherwise, the phone establishes a TCP connection.

The transport protocol in the configuration file must also be set to TLS

(corresponding to the transport type in the SIP Security Profile on Cisco Unified

CallManager).

Note If the device security mode in the configuration file is set to Authenticated or

Encrypted, but the phone has not received a CTL file, the phone will continuously

try to obtain a CTL file so that it can register securely.

A phone requests a configuration file whenever it resets and registers with

Cisco Unified CallManager.

A phone accesses a default configuration file named XmlDefault.cnf.xml from the

TFTP server when the following conditions exist:

•You have enabled auto-registration in Cisco Unified CallManager

•The phone has not been added to the Cisco Unified CallManager Database

•The phone is registering for the first time

If auto registration is not enabled and the phone has not been added to the

Cisco Unified CallManager Database, the phone registration request will be

rejected. In this case, the phone will reset and attempt to register repeatedly.

If the phone has registered before, the phone will access the configuration file

named SEPmac_address.cnf.xml, where mac_address is the MAC address of the

phone.

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

Understanding the Phone Startup Process

For more information about how the phone interacts with the TFTP server, refer

to the Cisco Unified CallManager System Guide, “Cisco TFTP” chapter.

The TFTP server generates these SIP configuration files:

•SIP IP Phone:

–

For unsigned and unencrypted files—SEP<mac>.cnf.xml

–

For signed files—SEP<mac>.cnf.xml.sgn

–

For signed and encrypted files—SEP<mac>.cnf.xml.enc.sgn

•Dial Plan—<dialplan>.xml

•Softkey Template—<softkey_template>.xml

The filenames are derived from the MAC Address and Description fields in the

Phone Configuration window of Cisco Unified CallManager Administration and

the devicename field in the Cisco Unified CallManager database. The MAC

address uniquely identifies the phone. For more information refer to the Cisco

Unified CallManager Administration Guide.

SIP Dial Rules

For Cisco SIP Unified IP phones, the administrator uses dial rules to configure

SIP phone dial plans. These dial plans must be associated with a SIP phone device

to enable dial plans to be sent to the configuration file. If the administrator does

not configure a SIP phone dial plan, the phone does not display any indication of

a dial plan.

For more information on configuring SIP dial rules, refer to the Cisco Unified

CallManager Administration Guide.

Understanding the Phone Startup Process

When connecting to the VoIP network, the Cisco Unified IP Phone goes through

a standard startup process, as described in Table 2-4. Depending on your specific

network configuration, not all of these steps may occur on your

Cisco Unified IP Phone.

OL-11524-01

Table 2-4 Cisco Unified IP Phone Startup Process

Step Description Related Topics

1. Obtaining Power

from the Switch.

If a phone is not using external power, the switch

provides in-line power through the Ethernet cable

attached to the phone.

•Providing Power to

the Phone,

page 2-4.

•Resolving Startup

Problems,

page 9-2.

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.

Resolving Startup

Problems, page 9-2.

3. Configuring VLAN. If the Cisco Unified IP Phone is connected to a

Cisco switch, the switch next informs the phone of

the voice VLAN defined on the switch port. The

phone needs to know its VLAN membership

before it can proceed with the Dynamic Host

Configuration Protocol (DHCP) request for an IP

address.

•Network

Configuration

Menu, page 4-7.

•Resolving Startup

Problems,

page 9-2.

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 static IP addresses

to each phone locally.

•Network

Configuration

Menu, page 4-7.

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

Understanding the Phone Startup Process

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.

Note You can also assign an alternative TFTP

server to use instead of the one assigned

by DHCP.

•Network

Configuration

Menu, page 4-7.

•Resolving Startup

Problems,

page 9-2.

6. Requesting the CTL

file.

The TFTP server stores the certificate trust list

(CTL) file. This file contains a list of Cisco

Unified CallManagers and TFTP servers that the

phone is authorized to connect to. It also contains

the certificates necessary for establishing a secure

connection between the phone and Cisco

Unified CallManager.

For more information,

refer to Cisco

Unified CallManager

7. Requesting the

Configuration File.

The TFTP server has configuration files, which

define parameters for connecting to Cisco

Unified CallManager and other information for

the phone.

•Understanding

Phone

Configuration

Files, page 2-8

•Resolving Startup

Problems,

page 9-2.

8. Contacting Cisco

Unified CallManager.

The configuration file defines how the Cisco

Unified IP Phone communicates with Cisco

Unified CallManager and provides a phone with

its load ID. After obtaining the file from the TFTP

server, the phone attempts to make a connection to

the highest priority Cisco Unified CallManager on

the list. If security is implemented, the phone

makes a TLS connection. Otherwise, it makes a

non-secure TCP connection.

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.

Note Auto-registration is disabled when

security is enabled on Cisco

Unified CallManager. In this case, the

phone must be manually added to the

Cisco Unified CallManager database.

Adding Phones to the Cisco Unified CallManager

Database

Before installing the Cisco Unified IP phone, you must choose a method for

adding phones to the Cisco Unified CallManager database. The following

sections describe these methods:

•Adding Phones with Auto-Registration, page 2-14

•Adding Phones with Auto-Registration and TAPS, page 2-15

•Adding Phones with Cisco Unified CallManager Administration, page 2-16

•Adding Phones with BAT, page 2-16

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones

OL-11524-01

Adding Phones with Auto-Registration

You can add phones with auto-registration without first gathering MAC addresses

from the phones.

Note Cisco recommends you use auto-registration to add less than 100 phones to your

network. To add more than 100 phones to your network, use the Bulk

Administration Tool (BAT). See the “Adding Phones with BAT” section on

page 2-16.

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.

You can use auto-registration to quickly enter phones into the

Cisco Unified CallManager database. You can then modify any settings, such as

the directory numbers, from Cisco Unified CallManager. Additionally, you can

move auto-registered phones to new locations and assign them to different device

pools without affecting their directory numbers.

Auto-registration is disabled by default.

For information about enabling and configuring auto-registration, refer to Cisco

Unified CallManager Administration Guide.

Note When you configure the cluster for mixed mode through the Cisco CTL client,

auto-registration is automatically disabled. When you configure the cluster for

non-secure mode through the Cisco CTL client, auto-registration is automatically

enabled.

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

Adding Phones to the Cisco Unified CallManager Database

Adding Phones with Auto-Registration and TAPS

You can add phones with auto-registration and TAPS without first gathering

MAC addresses from phones.

Note Cisco recommends you use auto-registration and TAPS to add less than 100

phones to your network. To add more than 100 phones to your network, use the

Bulk Administration Tool (BAT). See the “Adding Phones with BAT” section on

page 2-16.

TAPS, the Tool for Auto-Registered Phones Support, works with the Bulk

Administration Tool (BAT) to update phones that were already added to the

Cisco Unified CallManager database with dummy MAC addresses. Use TAPS to

update MAC addresses and download pre-defined configurations for phones.

To implement TAPS, you or the end-user dial a TAPS directory number and

follow voice prompts. When the process is complete, the phone will have

downloaded its directory number and other settings, and the phone will be

updated in Cisco Unified CallManager Administration with the correct MAC

address.

Auto-registration must be enabled in Cisco Unified CallManager Administration

(System > Cisco CallManager) for TAPS to function.

Note When you configure the cluster for mixed mode through the Cisco CTL client,

auto-registration is automatically disabled. When you configure the cluster for

non-secure mode through the Cisco CTL client, auto-registration is automatically

enabled.

Refer to Cisco Unified CallManager Bulk Administration Guide for detailed

instructions about BAT and about TAPS.

Understanding the Cisco Unified IP Phone

7970G/7971G-GE Components

The Cisco Unified IP Phone 7970G/7971G-GE includes these components on the

phone or as accessories for the phone:

•Network and Access Ports, page 3-5

•Handset, page 3-5

•Speakerphone, page 3-6

•Headset, page 3-6

Network and Access Ports

The back of the Cisco Unified IP Phone 7970G/7971G-GE includes these ports:

•Network port—Labeled 10/100 SW on the Cisco Unified IP Phone 7970G

and 10/100/1000 SW on the Cisco Unified IP Phone 7971G-GE

•Access port—Labeled 10/100 PC on the Cisco Unified IP Phone 7970G and

10/100/1000 PC on the Cisco Unified IP Phone 7971G-GE

Each port supports 10/100 or 10/100/1000 Mbps half- or full-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 and 1000 Mbps connections.

Use the SW 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

a switch over this connection. See the “Providing Power to the Phone” section on

page 2-4 for details.

Use the PC access port to connect a network device, such as a computer, to the

phone. You must use a straight-through cable on this port.

Handset

The handset is designed especially for use with a Cisco Unified IP Phone. It

includes a light strip that indicates incoming calls and voice messages waiting.

Speakerphone

By default, the speakerphone is enabled on Cisco Unified IP Phones

7970G/7971G-GE.

You can disable the speakerphone through the Cisco Unified CallManager

Administration application. To do so, choose Device > Phone and locate the

phone you want to modify. In the Phone Configuration web page for the phone,

check the Disable Speakerphone check box.

Headset

Although Cisco Systems performs some internal testing of third-party headsets

for use with the Cisco Unified IP Phones, Cisco does not certify or support

products from headset or handset vendors. Because of the inherent environmental

and hardware inconsistencies in the locations where Cisco Unified IP Phones are

deployed, there is not a single “best” solution that is optimal for all environments.

Cisco recommends that customers test the headsets that work best in their

environment before deploying a large number of units in their network.

In some instances, the mechanics or electronics of various headsets can cause

remote parties to hear an echo of their own voice when they speak to

Cisco Unified IP Phone users.

Cisco Systems recommends the use of good quality headsets that are screened

against unwanted radio frequency (RF) and audio frequency (AF) signals.

Depending on the quality of headsets and their proximity to other devices such as

cell phones and two-way radios, some audio noise may still occur.

The primary reason that support of a headset would be inappropriate for an

installation is the potential for an audible hum. This hum can either be heard by

the remote party or by both the remote party and the Cisco Unified IP Phone user.

Some potential humming or buzzing sounds can be caused by a range of outside

sources, for example, electric lights, being near electric motors, large PC

monitors. In some cases, a hum experienced by a user may be reduced or

eliminated by using a local power cube (CP-PWR-CUBE-3). See the “Safety”

section on page 3-3 for more information.

Chapter 3 Setting Up the Cisco Unified IP Phone

Understanding the Cisco Unified IP Phone 7970G/7971G-GE Components

Audio Quality Subjective to the User

Beyond the physical, mechanical and technical performance, the audio portion of

a headset must sound good to the user and the party on the far end. Sound is

subjective and Cisco cannot guarantee the performance of any headsets or

handsets, but some of the headsets and handsets on the sites listed below have

been reported to perform well on Cisco Unified IP Phones.

Nevertheless, it is ultimately still the customer’s responsibility to test this

equipment in their own environment to determine suitable performance.

For information about headsets, see:

http://vxicorp.com/cisco

http://plantronics.com

Connecting a Headset

To connect a headset to the Cisco Unified IP Phone, plug it into the Headset port

on the back of the phone. Press the Headset button on the phone to place and

answer calls using the headset.

You can use the headset with all of the features on the Cisco Unified IP Phone,

including the Volume and Mute buttons. Use these buttons to adjust the ear piece

volume and to mute the speech path from the headset microphone.

Disabling a Headset

You can disable the headset through the Cisco Unified CallManager

Administration application. If you do so, you also will disable the speakerphone.

To disable the headset from Cisco Unified CallManager Administration, choose

Device > Phone and locate the phone that you want to modify. In the Phone

Configuration web page for the phone, check the Disable Speakerphone and

Headset check box.

Using External Devices with Your Cisco Unified IP Phone

The following information applies when you use external devices with the

Cisco Unified IP Phone:

Cisco recommends the use of good quality external devices (speakers,

microphones, and headsets) that are shielded (screened) against unwanted radio

frequency (RF) and audio frequency (AF) signals.

Depending on the quality of these devices and their proximity to other devices

such as mobile phones or two-way radios, some audio noise may still occur. In

these cases, Cisco recommends that you take one or more of the following actions:

•Move the external device away from the source of the RF or AF signals.

•Route the external device cables away from the source of the RF or AF

signals.

•Use shielded cables for the external device, or use cables with a better shield

and connector.

•Shorten the length of the external device cable.

•Apply ferrites or other such devices on the cables for the external device.

Cisco cannot guarantee the performance of the system because Cisco has no

control over the quality of external devices, cables, and connectors. The system

will perform adequately when suitable devices are attached using good quality

cables and connectors.

Caution In European Union countries, use only external speakers, microphones, and

headsets that are fully compliant with the EMC Directive [89/336/EC].

After you install Cisco Unified IP Phones in your network, configure their

network settings, and add them to Cisco Unified CallManager, you must use the

Cisco Unified CallManager Administration application to configure telephony

features, optionally modify phone templates, set up services, and assign users.

This chapter provides an overview of these configuration and setup procedures.

Cisco Unified CallManager documentation provides detailed instructions for

these procedures.

For suggestions about how to provide users with information about features, and

what information to provide, see Appendix A, “Providing Information to Users

Via a Website.”

For information about setting up phones in non-English environments, see

Appendix C, “Supporting International Users.”

Configuring Corporate Directories

Cisco Unified CallManager uses a Lightweight Directory Access Protocol

(LDAP) directory to store authentication and authorization information about

users of Cisco Unified CallManager applications that interface with

Cisco Unified CallManager. Authentication establishes a user’s right to access

the system. Authorization identifies the telephony resources that a user is

permitted to use, such as a specific telephone extension.

To install and set up these features, refer to Installing and Configuring the Cisco

Unified Customer Directory Configuration Plugin. That manual guides you

through the configuration process for integrating Cisco Unified CallManager

with Microsoft Active Directory and Netscape Directory Server.

After the LDAP directory configuration completes, the Corporate Directory

service is enabled on your Cisco Unified IP Phone and allows users access to the

corporate directory.

Configuring Personal Directory

Personal Directory consists of the following features:

•Personal Address Book (PAB)

•Personal Fast Dials (Fast Dials)

•Address Book Synchronization Tool (TABSynch)

Users can access Personal Directory features by these methods:

•From a web browser—Users can access the PAB and Fast Dials features from

the Cisco Unified CallManager User Options web pages

•From the Cisco Unified IP Phone—Users can choose Directories > Personal

Directory to access the PAB and Fast Dials features from their phones

•From a Microsoft Windows application—Users can use the TABSynch tool

to synchronize their PABs with Microsoft Outlook.

To configure Personal Directory from a web browsers, users must access their

User Options web pages. You must provide users with a URL and login

information.

The default Cisco Unified IP Phone 7970 Series template uses buttons 1 and 2 for

lines and assigns buttons 3 through 8 as speed dial. Access other phone features,

such as call park, call forward, redial, hold, resume, voice messaging system,

conferencing, and so on using softkeys on the phone.

Configuring Softkey Templates

Using Cisco Unified CallManager Administration, you can manage softkeys

associated with applications that are supported by the Cisco Unified IP Phones

7970G/7971G-GE. Cisco Unified CallManager supports two types of softkey

templates: standard and nonstandard. Standard softkey templates include

Standard User and Standard Feature. An application that supports softkeys can

have one or more standard softkey templates associated with it. You can modify

a standard softkey template by making a copy of it, giving it a new name, and

making updates to that copied softkey template. You can also modify a

nonstandard softkey template.

Creating Custom Phone Rings

The Cisco Unified IP Phone ships with two default ring types that are

implemented in hardware: Chirp1 and Chirp2. Cisco Unified CallManager also

provides a default set of additional phone ring sounds that are implemented in

software as pulse code modulation (PCM) files. The PCM files, along with an

XML file (named Ringlist.xml) that describes the ring list options that are

available at your site, exist in the TFTP directory on each

Cisco Unified CallManager server.

The following sections describe how you can customize the phone rings that are

available at your site by creating PCM files and editing the Ringlist.xml file:

•Ringlist.xml File Format Requirements, page 6-3

•PCM File Requirements for Custom Ring Types, page 6-4

•Configuring a Custom Phone Ring, page 6-4

6-3

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones

OL-11524-01

Chapter 6 Customizing the Cisco Unified IP Phone

Creating Custom Phone Rings

Ringlist.xml File Format Requirements

The Ringlist.xml file defines an XML object that contains a list of phone ring

types. This file can include up to 50 ring types. Each ring type contains a pointer

to the PCM file that is used for that ring type and the text that will appear on the

Ring Type menu on a Cisco Unified IP Phone for that ring. The Cisco TFTP

server for each Cisco Unified CallManager contains this file.

The CiscoIPPhoneRinglist XML object uses the following simple tag set to

describe the information:

<Ring>

</Ring>

</CiscoIPPhoneRingList>

The following characteristics apply to the definition names. You must include the

required DisplayName and FileName for each phone ring type.

•DisplayName defines the name of the custom ring for the associated PCM file

that will display on the Ring Type menu of the Cisco Unified IP Phone.

•FileName specifies the name of the PCM file for the custom ring to associate

with DisplayName.

Note The DisplayName and FileName fields must not exceed 25 characters.

This example shows a Ringlist.xml file that defines two phone ring types:

<Ring>

<DisplayName>Analog Synth 1</DisplayName>

<FileName>Analog1.raw</FileName>

</Ring>

<Ring>

<DisplayName>Analog Synth 2</DisplayName>

<FileName>Analog2.raw</FileName>

</Ring>

Creating Custom Phone Rings

6-4

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones

OL-11524-01

PCM File Requirements for Custom Ring Types

The PCM files for the rings must meet the following requirements for proper

playback on Cisco Unified IP Phones:

•Raw PCM (no header)

•8000 samples per second

•8 bits per sample

•uLaw compression

•Maximum ring size—16080 samples

•Minimum ring size—240 samples

•Number of samples in the ring is evenly divisible by 240.

•Ring starts and ends at the zero crossing.

•To create PCM files for custom phone rings, you can use any standard audio

editing packages that support these file format requirements.

Configuring a Custom Phone Ring

To create custom phone rings for the Cisco Unified IP Phones 7970G/7971G-GE,

follow these steps:

Procedure

Step 1 Create a PCM file for each custom ring (one ring per file). Ensure the PCM files

comply with the format guidelines that are listed in the “PCM File Requirements

for Custom Ring Types” section on page 6-4.

Step 2 Place the new PCM files that you created in the TFTP server for each

Cisco Unified CallManager in your cluster. For more information, see the

“Software Upgrades” chapter in Cisco IP Telephony Platform Administration

Guide.

Step 3 Use an text editor to edit the Ringlist.xml file. See the “Ringlist.xml File Format

Requirements” section on page 6-3 for information about how to format this file

and for a sample Ringlist.xml file.

OL-11524-01

Chapter 6 Customizing the Cisco Unified IP Phone

Creating Custom Background Images

Step 4 Save your modifications and close the Ringlist.xml file.

Step 5 To cache the new Ringlist.xml file, stop and start the TFTP service by using

Cisco Unified CallManager Serviceability or disable and re-enable the “Enable

Caching of Constant and Bin Files at Startup” TFTP service parameter (located in

the Advanced Service Parameters).

Creating Custom Background Images

You can provide users with a choice of custom background images for the LCD

screen on their phones. Users can select a background image by choosing

Settings > User Preferences > Background Images on the phone.

The image choices that users see come from PNG images and an XML file (called

List.xml) that are stored on the TFTP server used by the phone. By storing your

own PNG files and editing the XML file on the TFTP server, you can designate

the background images from which users can choose. In this way, you can provide

custom images, such as your company logo.

The following sections describe how you can customize the background images

that are available at your site by creating your own PNG files and editing the

List.xml file:

•List.xml File Format Requirements, page 6-5.

•PNG File Requirements for Custom Background Images, page 6-6.

•Configuring a Custom Background Image, page 6-7

List.xml File Format Requirements

The List.xml file defines an XML object that contains a list of background

images. The List.xml file is stored in the following folder on the TFTP server:

Tip If you are manually creating the directory structure and the List.xml file, you must

ensure that the directories and files can be accessed by the user\CCMService,

which is used by the TFTP service.

Chapter 6 Customizing the Cisco Unified IP Phone

Creating Custom Background Images

6-6

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones

OL-11524-01

The List.xml file can include up to 50 background images. The images are in the

order that they appear in the Background Images menu on the phone. For each

image, the List.xml file contains one element type, called ImageItem. The

ImageItem element includes these two attributes:

•Image—Uniform resource identifier (URI) that specifies where the phone

obtains the thumbnail image that will appear on the Background Images menu

on a Phone.

•URL—URI that specifies where the phone obtains the full size image.

The following example shows a List.xml file that defines two images. The

required Image and URL attributes must be included for each image. The TFTP

URI that is shown in the example is the only supported method for linking to full

size and thumbnail images. HTTP URL support is not provided.

List.xml Example

<ImageItem Image=”TFTP:Desktops/320x212x12/TN-Fountain.png”

URL=”TFTP:Desktops/320x212x12/Fountain.png”/>

<ImageItem Image=”TFTP:Desktops/320x212x12/TN-FullMoon.png”

URL=”TFTP:Desktops/320x212x12/FullMoon.png”/>

</CiscoIPPhoneImageList>

The Cisco Unified IP Phone firmware includes a default background image. This

image is not defined in the List.xml file. The default image is always the first

image that appears in the Background Images menu on the phone.

PNG File Requirements for Custom Background Images

Each background image requires two PNG files:

•Full size image—Version that appears on the on the phone.

•Thumbnail image—Version that appears on the Background Images screen

from which users can select an image. Must be 25% of the size of the full size

image.

6-7

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones

OL-11524-01

Chapter 6 Customizing the Cisco Unified IP Phone

Creating Custom Background Images

Tip Many graphics programs provide a feature that will resize a graphic. An easy way

to create a thumbnail image is to first create and save the full size image, then use

the sizing feature in the graphics program to create a version of that image that is

25% of the original size. Save the thumbnail version using a different name.

The PNG files for background images must meet the following requirements for

proper display on the Cisco Unified IP Phone:

•Full size image—320 pixels (width) X 212 pixels (height).

•Thumbnail image—80 pixels (width) X 53 pixels (height).

•Color palette—Includes up to 12-bit color (4096 colors). You can use more

than 12-bit color, but the phone will reduce the color palette to12-bit before

displaying the image. For best results, reduce the color palette of an image to

12-bit when you create a PNG file.

Tip If you are using a graphics program that supports a posterize feature for

specifying the number of tonal levels per color channel, set the number of

tonal levels per channel to 16 (16 red X 16 green X 16 blue = 4096 colors).

Configuring a Custom Background Image

To create custom background images for the Cisco Unified IP Phone, follow

these steps:

Procedure

Step 1 Create two PNG files for each image (a full size version and a thumbnail version).

Ensure the PNG files comply with the format guidelines that are listed in the

“PNG File Requirements for Custom Background Images” section on page 6-6.

Step 2 Place the new PNG files that you created in the folder on the TFTP server for each

Cisco Unified CallManager in the cluster. For more information, see the

“Software Upgrades” chapter in the Cisco IP Telephony Platform Administration

Guide.

Chapter 6 Customizing the Cisco Unified IP Phone

Configuring Wideband Headset Codec

6-8

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones

OL-11524-01

Note Cisco recommends that you also store backup copies of custom image

files in another location. You can use these backup copies if the

customized files are overwritten when you upgrade

Cisco Unified CallManager.

Step 3 Use a text editor to edit the List.xml file. See the “List.xml File Format

Requirements” section on page 6-5 for the location of this file, formatting

requirements, and a sample file.

Step 4 Save your modifications and close the List.xml file.

Note When you upgrade Cisco Unified CallManager, a default List.xml file

will replace your customized List.xml file. After your customize the

List.xml file, make a copy of the file and store it in another location. After

upgrading Cisco Unified CallManager, replace the default List.xml file

with your stored copy.

Step 5 To cache the new List.xml file, stop and start the TFTP service by using

Cisco Unified CallManager Serviceability or disable and re-enable the Enable

Caching of Constant and Bin Files at Startup TFTP service parameter (located in

the Advanced Service Parameters).

Configuring Wideband Headset Codec

Users can configure a setting called Wideband Headset in the Audio Preferences

menu on the phone (choose > User Preferences > Audio Preferences>

Wideband Headset). This setting is Disabled by default, and should be enabled

only if the user’s headset supports wideband.

If Cisco Unified CallManager has been configured to use G.722 (G.722 is enabled

by default for Cisco Unified IP Phone Models 7941G, 7941G-GE, 7961G,

7961G-GE, 7970G, and 7971G-GE; other phone models may not support it), and

the far endpoint also supports G.722, the call will be connected using the G.722

codec in place of G.711. This occurs regardless of whether the user has enabled a

wideband headset, but if the headset is enabled, the headset user may notice

6-9

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones

OL-11524-01

Chapter 6 Customizing the Cisco Unified IP Phone

Configuring the Idle Display

greater audio sensitivity during the call. Greater sensitivity means improved audio

clarity but also means that more background noise can be heard by the far

endpoint—noise such as rustling papers or nearby conversations. Even without a

wideband headset, some users may prefer the additional sensitivity of G.722;

conversely, some users may be distracted by the additional sensitivity of G.722.

Two parameters in Cisco Unified CallManager Administration affect whether

wideband is supported for this Cisco Unified CallManager server and/or a specific

phone:

•Advertise G.722 Codec—Choose Cisco Unified CallManager

Administration > System > Enterprise Parameters. The default value of

this enterprise parameter is True, which means that all Cisco Unified IP

Phone Models 7941G, 7941G-GE, 7961G, 7961G-GE, 7970G, and

7971G-GE that are registered to this Cisco Unified CallManager will

advertise G.722 to Cisco Unified CallManager. If each endpoint in the

attempted call supports G.722 in its capabilites set, Cisco Unified CallManager

will choose that codec for the call. For more information, see the Cisco

Unified CallManager 5.1 Release Notes.

•Advertise G.722 Codec—Choose Cisco Unified CallManager

Administration > Device > Phone. The default value of this product-specific

parameter is to use the value specified in the enterprise parameter. If you want

to override this on a per-phone basis, choose Enabled or Disabled in the

Advertise G.722 Codec parameter on the Product Specific Configuration area

of the Phone Configuration window.

Configuring the Idle Display

You can specify an idle display that appears on the phone’s LCD screen. The idle

display is an XML service that the phone invokes when the phone has been idle

(not in use) for a designated period and no feature menu is open.

XML services that can be used as idle displays include company logos, product

pictures, and stock quotes.

Configuring the idle display consists of these general steps.

1. Formatting an image for display on the phone.

2. Configure Cisco Unified CallManager to display the image on the phone.

Resolving Startup Problems

After installing a Cisco Unified IP Phone into 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 3-15. 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

Startup Process, page 9-2

•Symptom: The Cisco Unified IP Phone Does Not Register with Cisco

Unified CallManager, page 9-3

•Symptom: Cisco Unified IP Phone Unable to Obtain IP Address, page 9-8

Symptom: The Cisco Unified IP Phone Does Not Go Through its

Normal Startup Process

When you connect a Cisco Unified IP Phone into the network port, the phone

should go through its normal startup process as described in the “Verifying the

Phone Startup Process” section on page 3-15, 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 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.

OL-11524-01

Chapter 9 Troubleshooting and Maintenance

Resolving Startup Problems

2. Verify that the phone is receiving power:

–

If you are using external power, verify that the electrical outlet is

functional.

–

If you are using in-line power, use the external power supply instead.

–

If you are using the external power supply, switch with a unit that you

know to be functional.

–

If you are using a Cisco Unified IP Phone 7971G-GE, make sure that the

phone is connected to a switch that supports IEEE 802.3af Class 3 (15.4

W in-line power at the switch port). For more information, see the

“Providing Power to the Phone” section on page 2-4.

3. If the phone still does not start up properly, power up the phone with the

handset off-hook. When the phone is powered up in this way, it attempts to

launch a backup software image.

4. If the phone still does not start up properly, perform a factory reset of the

phone. For instructions, see the “Performing a Factory Reset” section on

page 9-19.

If after attempting these solutions, the LCD screen on the Cisco Unified IP Phone

does not display any characters after at least five minutes, contact a Cisco

technical support representative for additional assistance.

Symptom: The Cisco Unified IP Phone Does Not Register with

Cisco Unified CallManager

If the phone proceeds past the first stage of the startup process (LED buttons

flashing on and off) but 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.

In addition, problems with security may prevent the phone from starting up

properly. See the “Troubleshooting Cisco Unified IP Phone Security” section on

page 9-12for more information.

Identifying Error Messages

As the phone cycles through the startup process, you can access status messages

that might provide you with information about the cause of a problem. See the

“Status Messages Screen” section on page 7-4 for instructions about accessing

status messages and for a list of potential errors, their explanations, and their

solutions.

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

You can determine the IP address of the TFTP server used by the phone by

pressing the Settings button on the phone, choosing Network Configuration,

and scrolling to the TFTP Server 1 option.

If you have assigned a static IP address to the phone, you must manually enter a

setting for the TFTP Server 1 option. See the “Network Configuration Menu”

section on page 4-7.

Chapter 9 Troubleshooting and Maintenance

Resolving Startup Problems

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.

See the “Network Configuration Menu” section on page 4-7 for instructions.

Verifying IP Addressing and Routing

You should verify the IP addressing and routing settings on the 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.

On the Cisco Unified IP Phone, press the Settings button, choose Network

Configuration, and look at the following options:

•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

the “Network Configuration Menu” section on page 4-7 for instructions.

If you are using DHCP, check the IP addresses distributed by your DHCP server.

Verifying DNS Settings

If you are using DNS to refer to the TFTP server or to

Cisco Unified CallManager, you must ensure that you have specified a DNS

server. Verify this setting by pressing the Settings button on the phone, choosing

Network Configuration, and scrolling to the DNS Server 1 option. 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.

You must also ensure that DNS is configured to do reverse look-ups.

Verifying Cisco Unified CallManager Settings

On the Cisco Unified IP Phone, press the Settings button, choose Network

Configuration, and look at the CallManager 1–5 options. 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. If none of

these 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 9-8 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 a situation, 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 start a service, follow these steps:

Procedure

Step 1 From Cisco Unified CallManager Administration, choose Application >

Cisco CallManager Serviceability.

Step 2 Choose Tools > Control Center.

Resolving Startup Problems

Step 3 From the Servers column, 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 Start button.

The Service Status symbol changes from a square to an arrow.

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 may be corrupted.

To create a new configuration file, follow these steps:

Procedure

Step 1 From Cisco Unified CallManager, choose Device > Phone > Find to locate the

phone experiencing problems.

Step 2 Choose Delete 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 2-13 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 or numbers remain in the Cisco Unified

CallManager database. They are called “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.

•Changing the buttons on a phone button template, or assigning a different

phone button template to a phone, may result in directory numbers that are no

longer accessible from the phone. The directory numbers are still assigned to

the phone in the Cisco Unified CallManager database, but there is no button

on the phone with which calls can be answered. These directory numbers

should be removed from the phone and deleted if necessary.

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 is enabled.

Review the information and procedures in the “Adding Phones to the Cisco

Unified CallManager Database” section on page 2-13 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 > Find from Cisco Unified CallManager Administration to search for the

phone based on its MAC Address. For information about determining a MAC

address, see the “Determining the MAC Address of a Cisco Unified IP Phone”

section on page 2-20.

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 9-7 for assistance.

Symptom: Cisco Unified IP Phone Unable to Obtain IP Address

If a phone is unable to obtain an IP address when it starts up, the phone may be

not be on the same network or VLAN as the DHCP server, or the switch port to

which the phone is connected may be disabled.

Make sure that the network or VLAN to which the phone is connected has access

to the DHCP server, and make sure that the switch port is enabled.

Chapter 9 Troubleshooting and Maintenance

Cisco Unified IP Phone Resets Unexpectedly

If users report that their phones are resetting during calls or while idle on their

desk, you should investigate the cause. If the network connection and

Cisco Unified CallManager connection are stable, a Cisco Unified IP Phone

should not reset on its own.

Typically, a phone resets if it has problems connecting to the Ethernet network or

to Cisco Unified CallManager. These sections can help you identify the cause of

a phone resetting in your network:

•Verifying Physical Connection, page 9-9

•Identifying Intermittent Network Outages, page 9-9

•Verifying DHCP Settings, page 9-10

•Checking Static IP Address Settings, page 9-10

•Verifying Voice VLAN Configuration, page 9-10

•Verifying that the Phones Have Not Been Intentionally Reset, page 9-11

•Eliminating DNS or Other Connectivity Errors, page 9-11

•Checking Power Connection, page 9-12

Verifying Physical Connection

Verify that the Ethernet connection to which the Cisco Unified IP Phone is

connected is up. For example, check if the particular port or switch to which the

phone is connected is down and that the switch is not rebooting. Also make sure

that there are no cable breaks.

Identifying Intermittent Network Outages

Intermittent network outages affect data and voice traffic differently. Your

network might have been experiencing intermittent outages without detection. If

so, data traffic can resend lost packets and verify that packets are received and

transmitted. However, voice traffic cannot recapture lost packets. Rather than

retransmitting a lost network connection, the phone resets and attempts to

reconnect its network connection.

Chapter 9 Troubleshooting and Maintenance

Cisco Unified IP Phone Resets Unexpectedly

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones

OL-11524-01

If you are experiencing problems with the voice network, you should investigate

whether an existing problem is simply being exposed.

Verifying DHCP Settings

Follow this process to help determine if the phone has been properly configured

to use DHCP:

1. Verify that you have properly configured the phone to use DHCP. See the

“Network Configuration Menu” section on page 4-7 for more information.

2. Verify that the DHCP server has been set up properly.

3. Verify the DHCP lease duration. Cisco recommends that you set it to 8 days.

Cisco Unified IP Phones send messages with request type 151 to renew their

DHCP address leases. If the DHCP server expects messages with request type

150, the lease will be denied, forcing the phone to restart and request a new

IP address from the DHCP server.

Checking Static IP Address Settings

If the phone has been assigned a static IP address, verify that you have entered the

correct settings. See the “Network Configuration Menu” section on page 4-7 for

more information.

Verifying Voice VLAN Configuration

If the Cisco Unified IP Phone appears to reset during heavy network usage (for

example, following extensive web surfing on a computer connected to same

switch as phone), it is likely that you do not have a voice VLAN configured.

Isolating the phones on a separate auxiliary VLAN increases the quality of the

voice traffic. See the “Understanding How the Cisco Unified IP Phone Interacts

with the VLAN” section on page 2-3 for details.

Chapter 9 Troubleshooting and Maintenance

Cisco Unified IP Phone Resets Unexpectedly

Verifying that the Phones Have Not Been Intentionally Reset

If you are not the only administrator with access to Cisco Unified CallManager,

you should verify that no one else has intentionally reset the phones.

You can check whether a Cisco Unified IP Phone received a command from

Cisco Unified CallManager to reset by pressing the Settings button on the phone

and choosing Status > Network Statistics. If the phone was recently reset one of

these messages appears:

•Reset-Reset—Phone closed due to receiving a Reset/Reset from

Cisco Unified CallManager administration.

•Reset-Restart—Phone closed due to receiving a Reset/Restart from

Cisco Unified CallManager administration.

Eliminating DNS or Other Connectivity Errors

If the phone continues to reset, follow these steps to eliminate DNS or other

connectivity errors:

Step 1 Use the Erase softkey to reset phone settings to their default values. See the

“Resetting or Restoring the Cisco Unified IP Phone” section on page 9-17 for

details.

Step 2 Modify DHCP and IP settings.

a. Disable DHCP. See the “Network Configuration Menu” section on page 4-7

for instructions.

b. Assign static IP values to the phone. See the “Network Configuration Menu”

section on page 4-7 for instructions. Use the same default router setting used

for other functioning Cisco Unified IP Phones.

c. Assign TFTP server. See the “Network Configuration Menu” section on

page 4-7 for instructions. Use the same TFTP server used for other

functioning Cisco Unified IP Phones.

Step 3 On the Cisco Unified CallManager server, verify that the local host files have the

correct Cisco Unified CallManager server name mapped to the correct IP address.

Step 4 From Cisco Unified CallManager, choose System > Server and verify that the

server is referred to by its IP address and not by its DNS name.

Step 5 From Cisco Unified CallManager, choose Device > Phone and verify that you

have assigned the correct MAC address to this Cisco Unified IP Phone. For

information about determining a MAC address, see the “Determining the MAC

Address of a Cisco Unified IP Phone” section on page 2-20.

Step 6 Power cycle the phone.

Checking Power Connection

In most cases, a phone will restart if it powers up using external power but loses

that connection and switches to PoE. Similarly, a phone may restart if it powers

up using PoE and then gets connected to an external power supply.

Phone.

Table 9-2 Cisco Unified IP Phone Troubleshooting

Summary Explanation

Daisy-chaining IP phones Daisy chaining (connecting an IP phone to another IP phone

through the access port) is not supported. Each IP phone should

directly connect to a switch port.

Poor quality when calling digital cell

phones using the G.729 protocol

In Cisco Unified CallManager, you can configure the network

to use the G.729 protocol (the default is G.711). When using

G.729, calls between an IP phone and a digital cellular phone

will have poor voice quality. Use G.729 only when absolutely

necessary.

Prolonged broadcast storms cause IP

phones to reset, or be unable to make

or answer a call

A prolonged Layer 2 broadcast storm (lasting several minutes)

on the voice VLAN may cause IP phones to reset, lose an active

call, or be unable to initiate or answer a call. Phones may not

come up until a broadcast storm ends.

Moving a network connection from

the phone to a workstation

If you are powering your phone through the network

connection, you must be careful if you decide to unplug the

phone’s network connection and plug the cable into a desktop

computer.

Caution The computer’s network card cannot receive power

through the network connection; if power comes

through the connection, the network card can be

destroyed. To protect a network card, wait 10

seconds or longer after unplugging the cable from

the phone before plugging it into a computer. This

delay gives the switch enough time to recognize that

there is no longer a phone on the line and to stop

providing power to the cable.

The RxType and the TxType statistics show the codec that is

being used for a conversation between this Cisco

Unified IP phone and the other device. These values of these

statistics should match. If they do not, verify that the other

device can handle the codec conversation or that a transcoder is

in place to handle the service.

See the “Call Statistics Screen” section on page 7-16 for

information about displaying these statistics.

Sound sample mismatch between the

phone and another device

The RxSize and the TxSize statistics show the size of the voice

packets that is being used a conversation between this Cisco

Unified IP phone and the other device. The values of these

statistics should match.

See the “Call Statistics Screen” section on page 7-16 for

information about displaying these statistics.

Gaps in voice calls Check the AvgJtr and the MaxJtr statistics. A large variance

between these statistics might indicate a problem with jitter on

the network or periodic high rates of network activity.

After you press these keys, the line buttons on the phone flash orange and then

green, and the phone goes through the factory reset process. This process can take

several minutes.

Do not power down the phone until it completes the factory reset process and the

main screen appears.

Using the Quality Report Tool

The Quality Report Tool (QRT) is a voice quality and general problem-reporting

tool for the Cisco Unified IP Phone. The QRT feature is installed as part of the

Cisco Unified CallManager installation.

You can configure users’ Cisco Unified IP Phones with QRT. When you do so,

users can report problems with phone calls by pressing the QRT softkey. This

softkey is available only when the Cisco Unified IP Phone is in the Connected,

Connected Conference, Connected Transfer, and/or OnHook states.

When a user presses the QRT softkey, a list of problem categories appears. The

user selects the appropriate problem category and this feedback is logged in an

XML file. Actual information logged depends on the user selection and whether

the destination device is a Cisco Unified IP Phone.

For more information about using QRT, refer to Cisco Unified CallManager

Features and Services Guide.

Monitoring the Voice Quality of Calls

To measure the voice quality of calls that are sent and received within the

network, Cisco Unified IP Phones use these statistical metrics that are based on

concealment events. The DSP plays concealment frames to mask frame loss in the

voice packet stream.

•Concealment Ratio metrics—Show the ratio of concealment frames over total

speech frames. An interval conceal ratio is calculated every 3 seconds.

9-21

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones

OL-11524-01

Chapter 9 Troubleshooting and Maintenance

Monitoring the Voice Quality of Calls

•Concealed Second metrics—Show the number of seconds in which the DSP

plays concealment frames due to lost frames. A severely “concealed second”

is a second in which the DSP plays more than five percent concealment

frames.

•MOS-LQK metrics—Use a numeric score to estimate the relative voice

listening quality. The Cisco Unified IP Phone calculates the mean opinion

score (MOS) for listening quality (LQK) based audible concealment events

due to frame loss in the preceding 8 seconds, and includes perceptual

weighting factors such as codec type and frame size.

MOS LQK scores are produced by a Cisco proprietary algorithm, Cisco Voice

Transmission Quality (CVTQ) index. Depending on the MOS LQK version

number, these scores might be compliant with the International

Telecommunications Union (ITU) standard P.564. This standard defines

evaluation methods and performance accuracy targets that predict listening

quality scores based on observation of actual network impairment.

Note Concealment ratio and concealment seconds are primary measurements based on

frame loss while MOS LQK scores project a “human-weighted” version of the

same information on a scale from 5 (excellent) to 1 (bad) for measuring listening

quality.

Listening quality scores (MOS LQK) relate to the clarity or sound of the received

voice signal. Conversational quality scores (MOS CQ such as G.107) include

impairment factors, such as delay, that degrade the natural flow of conversation.

You can access voice quality metrics from the Cisco Unified IP Phone by using

the Call Statistics screen (see the “Call Statistics Screen” section on page 7-16 )

or remotely by using Streaming Statistics (see the “Monitoring the Cisco

Unified IP Phone Remotely” chapter.

Using Voice Quality Metrics

To use the metrics for monitoring voice quality, note the typical scores under

normal conditions of zero packet loss , and use the metrics as a baseline for

comparison.

Chapter 9 Troubleshooting and Maintenance

Monitoring the Voice Quality of Calls

9-22

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1 (SIP), Cisco Unified IP Phones

OL-11524-01

It is important to distinguish significant changes from random changes in metrics.

Significant changes are scores that change about 0.2 MOS or greater and persist

in calls that last longer than 30 seconds. Conceal Ratio changes should indicate

greater than 3 percent frame loss.

MOS LQK scores can vary based on the codec that the Cisco Unified IP Phone

uses. The following codecs provide these maximum MOS LQK scores under

normal conditions with zero frame loss:

•G.711 codec gives 4.5 score

•G.719A/ AB gives 3.7 score

Note • CVTQ does not support wideband (7 kHz) speech codecs, as ITU has not

defined the extension of the technique to wideband. Therefore, MOS scores

that correspond to G.711 performance are reported for G.722 calls to allow

basic quality monitoring, rather than not reporting an MOS score.

•Reporting G.711-scale MOS scores for wideband calls through the use of CVTQ

allows basic quality classifications to be indicated as good/normal or

bad/abnormal. Calls with high scores (approximately 4.5) indicate high

quality/low packet loss, and lower scores (approximately 3.5) indicate low

quality/high packet loss.

•Unlike MOS, the Conceal Ratio and Concealed Seconds metrics remain valid

and useful for both wideband and narrowband calls.

A Conceal Ratio of zero indicates that the IP network is delivering frames and

packets on time with no loss.

Troubleshooting Tips

When you observe significant and persistent changes to metrics, use Table 9-4 for

general troubleshooting information.

Chapter 9 Troubleshooting and Maintenance

Monitoring the Voice Quality of Calls

Note Voice quality metrics do not account for noise or distortion, only frame loss.

Table 9-4 Changes to Voice Quality Metrics

Metric Change Condition

MOS LQK scores

decrease significantly

Network impairment from packet loss or high jitter:

•Average MOS LQK decreases could indicate

widespread and uniform impairment.

•Individual MOS LQK decreases indicate bursty

impairment.

Cross-check with Conceal Ratio and Conceal

Seconds for evidence of packet loss and jitter.

MOS LQK scores

decrease significantly

•Check to see if the phone is using a different

codec than expected (RxType and TxType).

•Check to see if the MOS LQK version changed

after a firmware upgrade.

Conceal Ratio and

Conceal Seconds

increase significantly

•Network impairment from packet loss or high

jitter.

Conceal Ratio is near or

at zero, but the voice

quality is poor

•Noise or distortion in the audio channel such as

echo or audio levels.

•Tandem calls that undergo multiple

encode/decode such as calls to a cellular

network or calling card network.

•Acoustic problems coming from a

speakerphone, handsfree cellular phone or

wireless headset.

Check packet transmit (TxCnt) and packet receive

(RxCnt) counters to verify that voice packets are

flowing.

Cleaning the Cisco Unified IP Phone

To clean your Cisco Unified IP phone, use a soft, dry cloth to wipe the phone and

the touchscreen. Do not apply liquids or powders directly on the phone. As with

all non-weather-proof electronics, liquids and powders can damage the

components and cause failures.

Disable the touchscreen before cleaning it so that you will not inadvertently

choose a feature from the pressure of the cleaning cloth. To disable the

touchscreen so that it will not respond to touch, press the Display button for more

than one second. The phone displays Touchscreen Disabled and the Display

button flashes green.

After one minute, the touchscreen automatically re-enables itself. To re-enable

the touchscreen before that, press the flashing Display button for more than one

second. The phone displays Touchscreen Enabled.
