Cisco Unified Communications Manager

the
Cisco Unified Communications Manager Administration Guide
or the context-sensitive help in the Cisco
Unified Communications Manager application to ensure that Cisco Unified Communications Manager is set
up properly to manage the phone and to properly route and process calls.
If you plan to use autoregistration, verify that autoregistration is enabled and is properly configured in Cisco
Unified Communications Manager Administration before you connect any Cisco Unified IP Phone to the
network. For information about enabling and configuring autoregistration, see the
Cisco Unified
Communications Manager Administration Guide
.

features to the Cisco Unified IP Phones.
In Cisco Unified Communications Manager Administration, you can add users to the database and associate
them with specific phones. In this way, users gain access their Cisco Unified Communications Manager User
Options page to configure items such as call forwarding, speed dialing, and voice messaging system options.
