Cisco IP Phone Hardware

Cisco IP Phone Hardware Overview

The Cisco IP Phone 7800 Series provides voice communication over an Internet Protocol (IP) network. The CiscoIPPhone 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 connects to your data network, it offers enhanced IP telephony features, including access to network information and services, and customizable features and services.

The Cisco IP Phone 7841 supports Gigabit ethernet connectivity.

When adding features to the phone line keys, you are limited by the number of line keys available. You cannot add more features than the number of line keys on your phone.

A Cisco IP Phone, like other network devices, must be configured and managed. These phones encode the following codecs:

  • G.711 a-law

  • G.711 mu-law

  • G.722

  • G722.2 AMR-WB

  • G.729a

  • G.729ab

  • iLBC

  • Opus

These phones decode the following codecs:

  • G.711 a-law

  • G.711 mu-law

  • G.722

  • G.729

  • G.729a

  • G.729b

  • G.729ab

  • iLBC

  • Opus


Caution

Use of a cell, mobile, or GSM phone, or two-way radio in close proximity to a CiscoIP Phone might cause interference. For more information, see the manufacturer documentation of the interfering device.

As with other network devices, you must configure Cisco 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. If your network requires it, however, you can manually configure information such as: an IP address, TFTP server, and subnet information.

Cisco IP Phones can interact with other services and devices on your IP network to provide enhanced functionality. For example, you can integrate Cisco Unified Communications Manager with the corporate Lightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for coworker 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.

Hardware Versions

We occasionally update our phone hardware to take advantage of new technology, with each version identified by a Product ID (PID) located on the back of your phone. Use the following table to determine if your phone is an early hardware release or a later one.

New phones must run Firmware Release 10.3(1) or later and you cannot downgrade to an earlier firmware release.

Phone Connections

Use an Ethernet cable to connect your phone to your LAN and enable the phone's full functionality. If your Ethernet port is equipped with Power over Ethernet (PoE), you can power the phone through the LAN port. Do not extend the LAN Ethernet cable outside the building. For your phone to work, it must be connected to the IP telephony network.
