Using your 7821 IPT Phone - Executive
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.
