Cisco Unified IP Conference Phone 8831
The Cisco Unified IP Conference Phone 8831 is a full-featured single line conference phone that provides
voice communication over an IP network. It functions much like a digital business phone, allowing you to
place and receive calls and to access features such as mute, hold, transfer, speed dial, call forward, and more.
In addition, because conference phones connect to your data network, they offer enhanced IP telephony
features, including access to network information and services, and customizable features and services. The
conference phones also support certain security features.
The conference phone provides a backlit LCD screen, support for up to ten speed-dial numbers, and a variety
of other sophisticated functions. Optional microphone extension kits provide enhanced room coverage that
can be further expanded by linking two units together.
The conference phone, like other network devices, must be configured and managed. The conference phones
encode G.711a, G.711u, G.729a, G.722, G.729ab, iLBC, and decode all variants of G.711 and G.729. The
conference phones also support 16-bit/16-kHz wideband audio.
Using a cell, mobile, or GSM phone, or two-way radio in close proximity to a Cisco Unified IP Conference
