Features of your Cisco Unified IP Phone
The Cisco Unified IP Conference Phone 8831 is a full-featured single line conference station 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 stations 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 station 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.
In addition to basic call-handling features, your conference station can provide enhanced productivity features
that extend your call-handling capabilities. Depending on configuration, the conference station supports:
•Access to network data, XML applications, and web-based services.
•Online customizing of conference station features and services from your User Options web pages.

Note
Wired extension microphone kit
The optional wired extension microphone kit includes two wired omni-directional microphones. Connecting
a microphone kit enhances the room coverage of the conference phone. The sound base has two wired
microphone ports and you can connect one or both wired microphones.
If the conference phone is connected to another sound base in Linked Mode, the primary base station supports
one or two wireless microphones, or it supports one wired microphone. The secondary unit supports only one
wired microphone; a wireless microphone cannot be connected to a secondary Sound Base. You cannot mix
microphone kits: if you plan to connect a microphone to both sound bases, they must both be wired microphones.
Wired and wireless microphones cannot be used at the same time, and the wireless microphones have a
higher priority. Attempting to connect a wired microphone to a conference phone that has paired or
connected channels results in a warning to the user that the wired microphone is disabled. To solve this
problem, unpair any paired or connected wireless microphones before connecting a wired microphone.
