Cisco Unified Communications Manager Configuration
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. Also, see the “Adding Phones to the Cisco Unified
Communications Manager Database” section on page 2-9.
You must use Cisco Unified Communications Manager Administration to configure and assign
telephony features to the Cisco Unified IP Phones. See the “Telephony Features Available for the Cisco
Unified IP Phone” section on page 8-2 for details.
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 CM User Option
page to configure items such as call forwarding, speed dialing, and voice messaging system options. See
the “Adding Users to Cisco Unified Communications Manager” section on page 8-33 for details.
