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 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.

What Networking Protocols Are Used?

Cisco IP Phones support several industry-standard and Cisco networking protocols required for voice communication. See Table 1 - 1 for an overview of the supported networking protocols.

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

Networking Protocol Purpose Usage Notes

Bootstrap Protocol (BootP)

Cisco Discovery Protocol (CDP)

Cisco IP Phone Administration Guide for Cisco CallManager 3.2, Cisco IP Phones 7960/7940/7910

78-10453-04

BootP enables a network device such as the Cisco 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.

If you are using BootP to assign IP addresses to the Cisco IP Phone, this is displayed in the network configuration settings on the phone.

The Cisco 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.

1-7

Chapter 1 An Overview of the Cisco IP Phone

What Networking Protocols Are Used?

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

Networking Protocol Purpose Usage Notes

Dynamic Host Configuration Protocol (DHCP)

DHCP dynamically allocates and assigns an IP address to network devices.

DHCP enables you to connect the IP phone into the network and become operational without manually assigning an IP address or configuring additional required network parameters.

Internet Protocol (IP) IP is a messaging protocol that addresses

and sends packets across the network.

DHCP is enabled by default. If disabled, you must manually configure the IP address, subnet mask, gateway, and an TFTP server on each phone locally.

Cisco recommends that you use DHCP custom option 150. With this method, you configure the TFTP server IP address as the option value. For additional supported DCHP configurations, see the Cisco CallManager System Guide.

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

Real-Time Transport (RTP)

Transmission Control Protocol (TCP)

Cisco IP Phone Administration Guide for Cisco CallManager 3.2, Cisco IP Phones 7960/7940/7910

1-8

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

TCP is a a connection-oriented transport protocol.

IP addresses, subnets, and gateways identifications are automatically assigned if you are using the Cisco 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 IP Phones use the RTP protocol to send and receive real-time voice traffic from other phones and gateways.

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

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

Networking Protocol Purpose Usage Notes

Trivial File Transfer Protocol (TFTP)

User Datagram Protocol (UDP)

TFTP allows you to transfer files over the network.

On the Cisco 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.

TFTP requires a TFTP server in your network, which can be automatically identified from the DHCP server. If more than one TFTP server is running in your network, you must manually assign a TFTP server to each phone locally.

Cisco IP Phones receive and process UDP messages.

What Features are Supported on the Cisco IP Phone?

The Cisco IP Phone functions much like a traditional analog phone, allowing you to place and receive telephone calls.

What Features are Supported on the Cisco IP Phone?

Feature Overview

Cisco IP Phones provide traditional telephony functionality, such as call forwarding and transferring, redialing, speed dialing, conference calling, and voice mail access. For an overview of all the supported telephony features and tips on configuring them, see the “Configuring Cisco IP Phones in

Cisco CallManager” section on page 6-2.

Because the Cisco IP Phones are connected to the rest of your IP network, they can interact with other services and devices to provide enhanced functionality. For example, you can integrate the Cisco 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 phone. Or, you can use XML to enable users to access information such as weather, stocks, quote of the day or other Web-based information. For information about configuring these services, see the “Configuring Corporate Directories” section on page 6-8 and the

“Setting Up User Services” section on page 6-8.

Finally, because the Cisco IP Phone is a network device, you can obtain detailed status information from it directly. This information can assist you in troubleshooting any problems users might encounter when using their IP phones. See Chapter 7, “Troubleshooting the Cisco IP Phone” for tips on using this information.
