Cisco Unified Communications Manager
The Cisco Unified IP Phone requires Cisco Unified Communications Manager to handle call processing.
Refer to Cisco Unified Communications Manager Administration Guide or to 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 auto-registration, verify that it is enabled and properly configured in Cisco Unified
Communications Manager Administration before connecting any Cisco Unified IP Phone to the network. For
information about enabling and configuring auto-registration, refer to
Cisco Unified Communications Manager
Administration Guide
.
You must use Cisco Unified Communications Manager Administration to configure and assign telephony
features to the Cisco Unified IP Phones.
In Cisco Unified Communications Manager Administration, you can add users to the database, add users to
user groups, and associate users to specific phones. In this way, users gain access their Cisco Unified CM
User Option page to configure items such as call forwarding and voice messaging system options.
