An Overview of the Cisco Unified IP Phone

C H A P T E R 1

The Cisco Unified IP Phone is a full-featured telephone that provides voice communication over an Internet Protocol (IP) network. It functions much like a digital business phone, allowing you to place and receive phone calls and to access features such as mute, hold, transfer, and speed dial. 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.

This manual describes the Cisco Unified IP Phone 7960G and the Cisco Unified IP Phone 7940G.

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