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.

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)—An existing 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 operations 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.

Severity 3 (S3)—Operational performance of the network is impaired while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Preface

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.

CHAPTER

An Overview of the Cisco Unified IP Phone

The Cisco Unified IP Phone 7961G and 7961G-GE (gigabit Ethernet version) and the 7941G and 7941G-GE (gigabit Ethernet version) are full-feature telephones that provide voice communication over an Internet Protocol (IP) network. The gigabit Ethernet Cisco Unified IP Phone 7961G-GE and 7941G-GE deliver the latest technology and advancements in Gigabit Ethernet VoIP telephony. The Cisco Unified IP Phone functions much like a digital business phone, allowing you to place and receive phone calls and to access features such as mute, hold, transfer, speed dial, call forward, and more. In addition, because the phone is connected to your data network, it offers enhanced IP telephony features, including access to network information and services, and customizeable features and services. The phone also supports security features that include file authentication, device authentication, signaling encryption, and media encryption.

A Cisco Unified IP Phone, like other network devices, must be configured and managed. These phones support G.711, G.729, G.729a, G.729b, G.729ab, and wideband (16bits, 16kHz) audio compression. The phone also encodes and decodes the G.722 wideband codec.

What Networking Protocols are Used?

Cisco Unified IP Phones support several industry-standard and Cisco networking protocols required for voice communication. Tabl e 1- 1 provides an overview of the networking protocols that the Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE support.

Table 1-1 Supported Networking Protocols on the Cisco Unified IP Phone

Networking Protocol Purpose Usage Notes

Bootstrap Protocol (BootP)

Cisco Discovery Protocol (CDP)

Dynamic Host Configuration Protocol (DHCP)

BootP enables a network device such as the Cisco Unified IP Phone to discover certain startup information, such as its IP address.

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.

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 to configure additional network parameters.

If you are using BootP to assign IP addresses to the Cisco Unified IP Phone, the BOOTP Server option shows “Yes” in the network configuration settings on the phone.

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.

DHCP is enabled by default. If disabled, you must manually configure the IP address, subnet mask, gateway, and a 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.

What Networking Protocols are Used?

Table 1-1 Supported Networking Protocols on the Cisco Unified IP Phone (continued)

Networking Protocol Purpose Usage Notes

Hypertext Transfer Protocol (HTTP)

HTTP is the standard way of transferring information and moving documents across the Internet and the web.

IEEE 802.1X The IEEE 802.1X standard defines a

client-server-based access control and authentication protocol that restricts unauthorized clients from connecting to a LAN through publicly accessible ports.

Until the client is authenticated,

802.1X access control allows only Extensible Authentication Protocol over LAN (EAPOL) traffic through the port to which the client is connected. After authentication is successful, normal traffic can pass through the port.

Internet Protocol (IP) IP is a messaging protocol that

addresses and sends packets across the network.

Cisco Unified IP Phones use HTTP for the XML services and for troubleshooting purposes.

The Cisco Unified IP Phone implements the IEEE 802.1X standard by providing support for the EAP-MD5 option for 802.1X authentication.

When 802.1X authentication is enabled on the phone, you should disable the PC port and voice VLAN. Refer to the “Supporting 802.1X

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

additional information.

To communicate using IP, network devices must have an assigned IP address, subnet, and gateway.

Real-Time Transport Protocol (RTP)

RTP is a standard protocol for transporting real-time data, such as interactive voice and video, over data networks.

Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE Administration Guide for Cisco Unified CallManager

1-6

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.

Cisco Unified IP Phones use the RTP protocol to send and receive real-time voice traffic from other phones and gateways.

What Networking Protocols are Used?

Table 1-1 Supported Networking Protocols on the Cisco Unified IP Phone (continued)

Networking Protocol Purpose Usage Notes

Real-Time Control Protocol (RTCP)

Skinny Client Control Protocol (SCCP)

Session Initiation Protocol (SIP)

Transmission Control Protocol (TCP)

RTCP works in conjunction with RTP to provide QoS data (such as jitter, latency, and round trip delay) on RTP streams.

SCCP includes a messaging set that allows communications between call control servers and endpoint clients such as IP Phones. SCCP is proprietary to Cisco Systems.

SIP is an emerging standard for setting up telephone calls, multimedia conferencing, and other types of communications on the Internet.

TCP is a connection-oriented transport protocol.

RTCP is disabled by default, but you can enable it on a per phone basis using Cisco Unified CallManager. For more information, see the

“Network Configuration Menu” section on page 4-27.

Cisco Unified IP Phones use SCCP for call control. You can configure the Cisco Unified IP Phone to use either SCCP or Session Initiation Protocol (SIP).

Cisco Unified IP Phones use SCCP for call control. You can configure the Cisco Unified IP Phone to use either SCCP or SIP.

Cisco Unified IP Phones use TCP to connect to Cisco Unified CallManager and to access XML services.

Transport Layer Security (TLS)

TLS is a standard protocol for securing and authenticating communications.

When security is implemented, Cisco Unified IP Phones use the TLS protocol when securely registering with 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 you want a phone to use a TFTP server other than the one specified by the DHCP server, you must manually assign the IP address of the TFTP server using the Network Configuration menu on the phone.

What Features are Supported on the Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE?

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 and for tips on configuring them, see the

“Telephony Features Available for the Cisco Unified IP 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 if your network requires it, you can manually configure an IP address, TFTP server, and subnet mask. 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-worker 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” section on page 5-16 and the

“Setting Up Services” section on page 5-18.

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.

For a summary of some of the key information that phone users need their system administrators to provide, see Appendix A, “Providing Information to Users Via

a Website.”

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.

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

and other documents.

Note Most security features are available only if a certificate trust list (CTL) is installed

on the phone. For more information about the CTL, refer to “Configuring the Cisco CTL Client” chapter in Cisco Unified CallManager Security Guide.

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 (MIC), but for additional security, you can specify in Cisco Unified CallManager Administration that a certificate be installed by using the CAPF

. Alternatively, you can install an LSC from the Security Configuration menu on the phone. See the “Configuring

Security on the Cisco Unified IP Phone” section on page 3-19 for

more information.

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

Feature Description

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.

Secure SRST reference After you configure a SRST reference for security and then reset the

dependent devices in Cisco Unified CallManager Administration, the TFTP server adds the SRST certificate to the phone cnf.xml file and sends the file to the phone. A secure phone then uses a TLS connection to interact with the SRST-enabled router.

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.

Signaling encryption Ensures that all SCCP 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 encrypt-

Encrypted configuration files Lets you ensure the privacy of phone configuration files.

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 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, the call progress icon to the right of the call duration timer in the phone LCD screen changes to this icon .

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, PSTN, the call may be

nonsecure even though it is encrypted within the IP network and has a lock icon associated with it.

Security Restrictions

A user cannot barge into an encrypted call if the phone that is used to barge is not configured for encryption. When barge fails in this case, a reorder tone (fast busy tone) plays on the phone on which the user initiated the barge.

If the initiator phone is configured for encryption, the barge initiator can barge into an authenticated or nonsecure call from the encrypted phone. After the barge occurs, Cisco Unified CallManager classifies the call as nonsecure.

Chapter 1 An Overview of the Cisco Unified IP Phone

If the initiator phone is configured for encryption, the barge initiator can barge into an encrypted call, and the phone indicates that the call is encrypted.

A user can barge into an authenticated call, even if the phone that is used to barge is nonsecure. The authentication icon continues to appear on the authenticated devices in the call, even if the initiator phone does not support security.

Chapter 1 An Overview of the Cisco Unified IP Phone

Overview

Cisco Unified IP phones and Cisco Catalyst switches have traditionally used Cisco Discovery Protocol (CDP) to identify each other and determine parameters such as VLAN allocation and inline power requirements. However, CDP is not used to identify any locally attached PCs, therefore Cisco Unified IP Phones provide an EAPOL pass-through mechanism, whereby a PC locally attached to the IP phone, may pass through EAPOL messages to the 802.1X authenticator in the LAN switch. This prevents the IP phone from having to act as the authenticator, yet allows the LAN switch to authenticate a data end point prior to accessing the network.

In conjunction with the EAPOL pass-through mechanism, Cisco Unified IP Phones provide a proxy EAPOL-Logoff mechanism. In the event that the locally attached PC is disconnected from the IP phone, the LAN switch would not see the physical link fail, because the link between the LAN switch and the IP phone is maintained. To avoid compromising network integrity, the IP phone sends an EAPOL-Logoff message to the switch, on behalf of the downstream PC, which triggers the LAN switch to clear the authentication entry for the downstream PC.

Understanding Security Features for Cisco Unified IP Phones

The Cisco Unified IP phones also contain an 802.1X supplicant, in addition to the EAPOL pass-through mechanism. This supplicant allows network administrators to control the connectivity of IP phones to the LAN switch ports. The initial release of the IP phone 802.1X supplicant implements the EAP-MD5 option for

802.1X authentication.

Required Network Components

Support for 802.1X authentication on Cisco Unified IP Phones requires several components, including:

• Cisco Unified IP Phone—The phone acts as the 802.1X supplicant, which

initiates the request to access the network.

• Cisco Secure Access Control Server (ACS) (or other third-party

authentication server)—The authentication server and the phone must both be configured with a shared secret that is used to authenticate the phone.

• Cisco Catalyst Switch (or other third-party switch)—The switch must support

802.1X so it can act as the authenticator and pass the messages between the phone and the authentication server. When the exchange is completed, the switch then grants or denies the phone access to the network.

Chapter 1 An Overview of the Cisco Unified IP Phone

Understanding Security Features for Cisco Unified IP Phones

Best Practices—Requirements and Recommendations

• Enable 802.1X Authentication—If you want to use the 802.1X standard to

authenticate Cisco Unified IP Phones, be sure that you have properly configured the other components before enabling it on the phone. See the

“802.1X Authentication and Status” section on page 4-40 for more

information.

• Configure PC Port—The 802.1X standard does not take into account the use

of VLANs and thus recommends that only a single device should be authenticated to a specific switch port. However, some switches (including Cisco Catalyst switches) support multi-domain authentication. The switch configuration determines whether you can connect a PC to the phone’s PC port.

–

Enabled—If you are using a switch that supports multi-domain authentication, you can enable the PC port and connect a PC to it. In this case, Cisco Unified IP Phones support proxy EAPOL-Logoff to monitor the authentication exchanges between the switch and the attached PC. For more information about IEEE 802.1X support on the Cisco Catalyst switches, refer to the Cisco Catalyst switch configuration guides at:

–

Disabled—If the switch does not support multiple 802.1X-compliant devices on the same port, you should disable the PC Port when 802.1X authentication is enabled. See the “Security Configuration Menu”

section on page 4-25 for more information. If you do not disable this port

and subsequently attempt to attach a PC to it, the switch will deny network access to both the phone and the PC.

• Configure Voice VLAN—Because the 802.1X standard does not account for

VLANs, you should configure this setting based on the switch support.

–

Enabled—If you are using a switch that supports multi-domain authentication, you can continue to use the voice VLAN.

–

Disabled—If the switch does not support multi-domain authentication, disable the Voice VLAN and consider assigning the port to the native VLAN. See the “Security Configuration Menu” section on page 4-25 for more information.

• Enter MD5 Shared Secret—If you disable 802.1X authentication or perform

a factory reset on the phone, the previously configured MD5 shared secret is deleted. See the “802.1X Authentication and Status” section on page 4-40 for more information.

Cisco Unified CallManager is an open and industry-standard call processing system. Cisco Unified CallManager software sets up and tears down calls between phones, integrating traditional PBX functionality with the corporate IP network. Cisco Unified CallManager manages the components of the IP telephony system—the phones, the access gateways, and the resources necessary for such features as call conferencing and route planning. Cisco Unified CallManager also provides:

• Firmware for phones

• Authentication and encryption (if configured for the telephony system)

• Configuration file and CTL file, via TFTP service

• Phone registration

Understanding How the Cisco Unified IP Phone Interacts with the VLAN

The Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE have an internal Ethernet switch, enabling forwarding of packets to the phone, and to the access port and the network port on the back of the phone.

If a computer is connected to the access port, the computer and the phone share the same physical link to the switch and share the same port on the switch. This shared physical link has the following implications for the VLAN configuration on the network:

• The current VLANs might be configured on an IP subnet basis. However,

additional IP addresses might not be available to assign the phone to the same subnet as other devices connected to the same port.

• Data traffic present on the VLAN supporting phones might reduce the quality

of Voice-over-IP traffic.

Providing Power to the Cisco Unified IP Phone

• Network security may indicate a need to isolate the VLAN voice traffic from

the VLAN data traffic.

You can resolve these issues by isolating the voice traffic onto a separate VLAN. The switch port that the phone is connected to would be configured to have separate VLANs for carrying:

• Voice traffic to and from the IP phone (auxiliary VLAN on the Cisco Catalyst

6000 series, for example)

• Data traffic to and from the PC connected to the switch through the access

port of the IP phone (native VLAN)

Isolating the phones on a separate, auxiliary VLAN increases the quality of the voice traffic and allows a large number of phones to be added to an existing network where there are not enough IP addresses for each phone.

For more information, refer to the documentation included with a Cisco switch. You can also access related documentation at this URL:

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.)

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

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.

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.

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.A phone requests a configuration file whenever it resets and registers with Cisco Unified CallManager.

Understanding the Phone Startup Process

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.

Understanding the Phone Startup Process

When connecting to the VoIP network, the Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE go through a standard startup process that is described in Tab le 2- 4. Depending on your specific network configuration, not all of these steps may occur on your Cisco Unified IP Phone.

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.

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.

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.

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.

5. Accessing a TFTP

Server

6. Requesting the CTL

file

7. Requesting the

Configuration File

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.

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.

The TFTP server has configuration files, which define parameters for connecting to Cisco Unified CallManager and other information for the phone.

Step Description Related Topics

1. 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.

Resolving Startup Problems, page 9-2.

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. These sections describe the methods:

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

Adding Phones to the Cisco Unified CallManager Database

You can add phones with auto-registration and TAPS without first gathering MAC addresses from phones.

Note You should 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.

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 Cisco Unified CallManager automatically disables auto-registration if you

configure the cluster-wide security mode for authentication and encryption through the Cisco CTL client.

Refer to Cisco Unified CallManager Bulk Administration Guide for detailed instructions about BAT and about TAPS.

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.

To connect a handset to the Cisco Unified IP Phone, plug the cable into the handset and the Handset port on the back of the phone.

Speakerphone

By default, the speakerphone is enabled on the Cisco Unified IP Phone.

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 external devices, like headsets that are 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 cell phones and two-way radios, some audio noise may still occur. See the “Using External Devices with Your Cisco Unified IP Phone”

section on page 3-8 for more information.

Understanding the Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE Components

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. See the “Safety” section on page 3-3 for more information.

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, For information about headsets, refer to:

http://www.vxicorp.com/cisco

http://www.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.

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 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 headsets that are fully compliant

with the EMC Directive [89/336/EC].
