Supported Features
The Cisco Unified IP Conference Phones 8831 and 8831NR function much like digital business or conference
phones, and allow you to place and receive teleconference phone calls. In addition to traditional telephony
features, the conference phone includes features that enable you to administer and monitor the conference
phone as a network device.
The Cisco Unified IP Conference Phone 8831 supports wired and wireless microphones. The Cisco Unified
IP Conference Phone 8831NR supports only wired microphones.
Feature Overview
The Cisco Unified IP Conference Phone not only provides traditional telephony functionality, such as call
forward and transfer, redial, and voice message system access, but it supports a full range of conference
features. The conference phone also offers support for a variety of other features, such as WebDialer.
As with other network devices, the conference phone must be configured in order to access Cisco Unified
Communications Manager and the rest of the IP network. By using DHCP for this process, you have fewer
settings to configure on a device, but if your network requires it, an IP address, the TFTP server, and subnet
information can be configured manually.
Conference phones can interact with other services and devices on your IP network to provide enhanced
functionality. For example, you can integrate Cisco Unified Communications Manager with the corporate
Lightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for coworker

Usage Notes
TFTP requires a TFTP server in
your network, which can be
automatically identified from the
DHCP server. If you want a phone
to use a TFTP server other than the
one specified by the DHCP server,
you must manually assign the IP
address of the TFTP server by using
the Network Setup menu on the
phone.
For more information, see "Cisco
TFTP" chapter in the Cisco Unified
Communications Manager System
Guide.
Cisco Unified IP Phones transmit
and receive RTP streams, which
utilize UDP.
