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.

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.
Note
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.

Caution
Use only a soft, dry cloth to wipe your conference station display screen. Do not use any liquids or powders
on the phone, as they can contaminate phone components and cause failures.
Phone connections
Network and power are connected to the phone from the Sound Base. The mini-USB connection for the DCU,
the wired microphone ports and the daisy chain port for the Linked Mode feature are also located on the base.

Power-saving mode
Your conference station supports the Cisco EnergyWise (EW) program. Your system administrator sets up
sleep (power down) and wake (power up) times for your conference station to save energy. In the sleep state,
the LED for the sound base Mute button becomes solid gray, and the DCU powers off.
Ten minutes before the scheduled sleep time, you receive a message that the conference station will power
down at a specific time. If the power-saving mode is enabled by your system administrator, you hear your
ringtone play. The ringtone plays according to the following schedule:
At 10 minutes before power down, the ringtone plays four times
•
At 7 minutes before power down, the ringtone plays four times
•
At 4 minutes before power down, the ringtone plays four times
•
At 30 seconds before power down, the ringtone plays 15 times or until the phone powers down
•
If your conference station is inactive (idle) at the sleep time, it powers down. If your conference station is
active (for example, on a call), it waits until it has been inactive for a period of time before removing power.
After the conference station goes to sleep, press the Mute button on the sound base to wake the conference
station up. You cannot wake the conference station using the DCU. After it is inactive for a period of time,
the conference station goes back to sleep. At the set wake time, the conference station powers up.
Wake and sleep times are also linked to the configured days that you normally work. If your requirements
change (for example, your work hours or work days change), contact your system administrator to have your
conference station reconfigured.
For more information about EnergyWise and your conference station, contact your system administrator.
