Cisco Unified IP Conference Phone 8831 Components
The Cisco Unified IP Conference Phone 8831 includes these components on the conference phone or as
accessories for the conference phone.
Network Ports
The underside of the conference phone sound base has a single network port. This port is labeled LAN.
Your conference phone has a 10/100 Base-T autosensing Ethernet port. This port supports Mbps half- or
full-duplex connections to external devices. You can use either Category 3 or 5, or 5e cabling for 10-Mbps
connections, but you must use Category 5 or 5e for 100 Mbps connections.
Use the ethernet network port to connect the conference phone to the network. You must use a straight-through
cable on this port. The conference phone can also obtain inline power from a switch over this connection
(PoE).

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
Note
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.
