Directories
The Cisco Unified IP Conference Phone 8831 identifies incoming messages and categorizes them for users on
the screen. This feature allows you to quickly and effectively return calls using direct dial-back capability. The
corporate directory integrates with the Lightweight Directory Access Protocol Version 3 (LDAPv3) standard
directory.
Apps
The Apps soft key allows you to enter the Applications menu, where you are able to adjust display contrast, select
background images (if available), and select from a large number of unique ringer sounds through the User
Preference menu. Network configuration preferences also can be set up (usually by the system administrator).
Configuration can be either automatically or manually set up for Dynamic Host Control Protocol (DHCP), Trivial
File Transfer Protocol (TFTP), Cisco Unified Communications Manager, and backup Cisco Unified
Communications Manager instances.
Help
The online Help feature gives you information about the phone keys, buttons, and features. The pixel display
allows for more flexible feature navigation and significantly expands the information viewed when using features
such as Services, Information, Messages, and Directory. For example, the Directory button can show local and
server-based directory information.
Hold, Mute, and Redial
keys
The Mute key is a fixed key. When it is active, the LED flashes on the Cisco Unified IP Conference Phone 8831 as
well as on the optional wired and wireless microphone kits. Hold and Redial are provided as soft keys associated
with the screen, and are always at the same position for easy access.
Display
The conference station has a large high-resolution, graphical 3.5-inch backlit display (396 x 162 pixels).
Speakerphone
The Cisco Unified IP Conference Phone 8831 offers full-duplex high-quality wideband speakerphone technology.
Included are Automatic Gain Control, comfort-noise generation, silence suppression and voice activity detection,
Echo Suppression, and dynamic noise reduction, which reduces noise by up to 9 dB from constant noise sources
such as fans or heating, ventilation, and air conditioning (HVAC) systems.
A two-way high-fidelity loudspeaker system provides superior speech clarity versus traditional conferencing
systems.
