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, or 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.

CHAP T ER

An Overview of the Cisco Unified IP Phone

The Cisco Unified IP Phone 7975G, 7971G-GE (gigabit Ethernet version), 7970G, 7965G, and 7945G are full-featured telephones that provide voice communication over an Internet Protocol (IP) network. They function much like digital business phones, 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 Cisco Unified IP Phones are connected to your data network, they offer enhanced IP telephony features, including access to network information and services, and customizeable features and services. The phones also support security features that include file authentication, device authentication, signaling encryption, and media encryption.

The Cisco Unified IP Phone 7975G, 7971G-GE, 7970G, 7965G, and 7945G each provide a color screen (touchscreen for the 7975G, 7971G-GE, and the 7970G), support for line or speed dial numbers, context-sensitive online help for buttons and features, and a variety of other sophisticated functions.

A Cisco Unified IP Phone, like other network devices, must be configured and managed. These phones encode G.711a, G.711µ, G.722, G.729a, G.729ab, iLBC, and decode G.711a, G.711µ, G722, iLBC, and G.729, G729a, G.729b, and G.729ab. These phones also support uncompressed wideband (16bits, 16kHz) audio.

Chapter 1 An Overview of the Cisco Unified IP Phone

What Networking Protocols are Used?

Cisco Unified IP Phones support several industry-standard and Cisco networking protocols required for voice communication. Table 1 - 2 provides an overview of the networking protocols that the Cisco Unified IP Phones 7975G, 7971G-GE, 7970G, 7965G, and 7945G support.

Table 1-2 Supported Networking Protocols on the Cisco Unified IP Phone

Networking Protocol Purpose Usage Notes

Bootstrap Protocol (BootP) BootP enables a network device such as the

Cisco Unified IP Phone to discover certain startup information, such as its IP address.

Cisco Discovery Protocol (CDP)

Cisco Peer-to-Peer Distribution Protocol (CPPDP)

Dynamic Host Configuration Protocol (DHCP)

Hypertext Transfer Protocol (HTTP)

Hypertext Transfer Protocol Secure (HTTPS)

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.

CPPDP is a Cisco proprietary protocol used to form a-peer-to-peer hierarchy of devices. CPPDP is also used to copy firmware or other files from peer devices to neighboring devices.

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 needing to manually assign an IP address or configure additional network parameters.

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

Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol with the SSL/TLS protocol to provide encryption and secure identification of servers.

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.

CPPDP is used by the Peer Firmware Sharing feature.

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 DHCP configurations, refer to Dynamic Host

Configuration Protocol and Cisco TFTP in

the Cisco Unified Communications Manager System Guide.

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

Cisco Unified IP Phones do not support the use of IPv6 addresses in the URL. You cannot use a literal IPv6 address in the URL or a hostname that maps to an IPv6 address.

Web applications with both HTTP and HTTPS support have two URLs configured. Cisco Unified IP Phone that support HTTPS choose the HTTPS URL out of the two URLs.

Chapter 1 An Overview of the Cisco Unified IP Phone

What Networking Protocols are Used?

Table 1-2 Supported Networking Protocols on the Cisco Unified IP Phone (continued)

Networking Protocol Purpose Usage Notes

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.

Link Layer Discovery Protocol (LLDP)

LLDP is a standardized network discovery protocol (similar to CDP) that is supported on some Cisco and third-party devices.

The Cisco Unified IP Phone implements the IEEE 802.1X standard by providing support for the following authentication methods: EAP-FAST, EAP-TLS, and EAP-MD5.

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

Authentication on Cisco Unified IP Phones, page 1-19 for additional information.

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

IP addresses, subnets, and gateways identifications are automatically assigned if you are using the Cisco Unified IP Phone with Dynamic Host Configuration Protocol (DHCP). If you are not using DHCP, you must manually assign these properties to each phone locally.

The Cisco Unified IP Phone supports concurrent IPv4 and IPv6 addresses. Configure the IP addressing mode (IPv4 only, IPv6 only, and both IPv4 and IPv6) in Cisco Unified Communications Manager Administration. For more information, refer to Internet Protocol Version 6 (IPv6) in the

Cisco Unified Communications Manager Features and Services Guide.

The Cisco Unified IP Phone supports LLDP on the PC port.

What Networking Protocols are Used?

Table 1-2 Supported Networking Protocols on the Cisco Unified IP Phone (continued)

Networking Protocol Purpose Usage Notes

Link Layer Discovery Protocol-Media Endpoint Devices (LLDP-MED)

Real-Time Control Protocol (RTCP)

Real-Time Transport Protocol (RTP)

Session Initiation Protocol (SIP)

Skinny Client Control Protocol (SCCP)

LLDP-MED is an extension of the LLDP standard developed for voice products.

RTCP works with Real-Time Transport Protocol (RTP) to provide QoS data (such as jitter, latency, and round trip delay) on RTP streams.

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

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.

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.

The Cisco Unified IP Phone supports LLDP-MED on the SW port to communicate information such as:

• Voice VLAN configuration

• Device discovery

• Power management

• Inventory management

For more information about LLDP-MED support, see the LLDP-MED and Cisco Discovery Protocol white paper:

http://www.cisco.com/en/US/tech/tk652/tk70 1/technologies_white_paper0900aecd804cd4 6d.shtml

RTCP is disabled by default, but you can enable it on a per-phone basis using Cisco Unified Communications Manager. For more information, see Network Configuration,

page 4-32.

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

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.

You can configure the Cisco Unified IP Phone to use either SIP or Skinny Client Control Protocol (SCCP).

Cisco Unified IP Phones do not support the SIP protocol when the phones are operating in IPv6 address mode.

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).

What Networking Protocols are Used?

Table 1-2 Supported Networking Protocols on the Cisco Unified IP Phone (continued)

Networking Protocol Purpose Usage Notes

Session Description Protocol (SDP)

Transmission Control Protocol (TCP)

Transport Layer Security (TLS)

Trivial File Transfer Protocol (TFTP)

User Datagram Protocol (UDP)

SDP is the portion of the SIP protocol that determines which parameters are available during a connection between two endpoints. Conferences are established using only the SDP capabilities that are supported by all endpoints in the conference.

TCP is a connection-oriented transport protocol.

TLS is a standard protocol for securing and authenticating communications.

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.

UDP is a connectionless messaging protocol for delivery of data packets.

SDP capabilities, such as codec types, DTMF detection, and comfort noise, are normally configured on a global basis by Cisco Unified Communications Manager or Media Gateway in operation. Some SIP endpoints may allow these parameters to be configured on the endpoint itself.

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

When security is implemented, Cisco Unified IP Phones use the TLS protocol when securely registering with Cisco Unified Communications Manager.

For more information, refer to the

Cisco Unified Communications Manager Security Guide.

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.

For more information, refer to Cisco TFTP in the Cisco Unified Communications Manager System Guide.

Cisco Unified IP Phones transmit and receive RTP streams, which utilize UDP.

IPv6 Support on Cisco Unified IP Phones

The Cisco Unified IP Phone uses the internet protocol to provide voice communication over the network. Previous to Cisco Unified Communications Manager release 8.0, only the internet protocol version 4 (IPv4) was supported. Because it uses a 32-bit address, IPv4 cannot meet the increased demands for unique IP addresses for all devices that can connect to the internet. Internet Protocol version 6 (IPv6) is an updated version of the current Internet Protocol, IPv4. IPv6 uses a 128-bit address and provides end-to-end security capabilities, enhanced Quality of Service (QoS), and increased number of available IP addresses.

The Cisco Unified IP Phone supports IPv4 only addressing mode, IPv6 only addressing mode, as well as an IPv4/IPv6 dual stack addressing mode. In IPv4, you can enter each octet of the IP address on the phone in dotted decimal notation; for example, 192.240.22.5. In IPv6, you can enter each octet of the IP address in hexadecimal notation with each octet separated by a colon; for example, 2005:db8:0:1:ef8:9876:ba72:dc9a. The phone truncates and removes leading zeros when it displays the IPv6 address.

OL-23092-01

Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager 8.5

1-9

What Networking Protocols are Used?

Cisco Unified IP Phones support both IPv4 and an IPv6 address transparently, so users can handle all calls on the phone to which they are accustomed. Cisco Unified IP Phones support the use of IPv6 only with Cisco Unified Communications Manager release 7.1 and only with the Skinny Call Control Protocol (SCCP).

Cisco Unified IP Phones do not support URLs with IPv6 addresses in the URL. This affects all IP Phone Service URLs, including services, directories, messages, help, and any restricted web services that require the phone to use the HTTP protocol to validate the credentials with the Authentication URL. If you configure Cisco Unified IP Phone services for Cisco Unified IP Phones, you must configure the phone and the servers that support the phone service with IPv4 addresses.

If you configure IPv6 Only as the IP Addressing Mode for phones that are running SIP, the Cisco TFTP service overrides the IP Addressing Mode configuration and uses IPv4 Only in the configuration file.

For more information on deploying IPv6 in your Cisco Unified Communications network, refer to

Internet Protocol Version 6 (IPv6) in Cisco Unified Communications Manager Features and Services

Guide and Deploying IPv6 in Unified Communications Networks with Cisco Unified Communications Manager.

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 Telephony Features Available for the Phone,

page 5-1.

As with other network devices, you must configure Cisco Unified IP Phones to prepare them to access Cisco Unified Communications Manager 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, subnet information, and so on. 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 Configuring Corporate Directories, page 5-24 and

Setting Up Services, page 5-28.

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.
