Cisco Unified 7821 IP Phone Overview

The Cisco Unified 7821 SIP Phone provides 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. In addition, the Cisco Unified

7821 SIP Phone supports features such as mute, hold, transfer,

conference, call forward, and more.

A Cisco Unified IP Phone, like other network devices, must be

configured and managed. These phones encode G.711a, G.711mu,

G.729a, and G.729ab, and decode G.711a, G.711mu, G.729,

G.729a, and G.729ab

Caution

Using a cell, mobile, or GSM phone, or two-way radio

in close proximity to a Cisco Unified IP Phone might cause

interference.
