An Overview of the Cisco Unified IP Phone

The Cisco Unified IP Phone 6921, 6941, and 6961 provide voice communication over an Internet Protocol (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, and decode G.711a, G.711µ, G.729, G.729a, and G.729ab.
