An Overview of the Cisco Unified IP Phone

The Cisco Unified IP Phones 8941 and 8945 provide voice communication over an IP network. 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.

A Cisco Unified IP Phone, like other network devices, must be configured and managed. These phones encode G.711a, G.711µ, G.729, G.729a, G.729ab, iLBC, and decode G.711a, G.711µ, G.729, G.729a, G.729ab, and iLBC.

This chapter includes the following topics:

•Understanding the Cisco Unified IP Phones 8941 and 8945, page 1-2

•What Networking Protocols are Used?, page 1-4

•What Features are Supported on the Cisco Unified IP Phone 8941 and 8945?, page 1-7

•Overview of Configuring and Installing Cisco Unified IP Phones, page 1-17

•Terminology Differences, page 1-24

Caution Using a cell, mobile, or GSM phone, or two-way radio in close proximity to a Cisco Unified IP Phone may cause interference. For more information, refer to the manufacturer’s documentation of the interfering device.
