Note The Cisco Unified IP Phone displays the date and time from Cisco Unified CM. If the Cisco Unified CM
server is located in a different time zone than the phones, the phones will not display the correct
local time.

Cisco Unified Communications Manager Configuration

The Cisco Unified IP Phone requires Cisco Unified CM 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 CM 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 CM Database” section on page 2-8.
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 5-1 for details.
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, speed dialing, and voice messaging
system options. See the “Adding Users to Cisco Unified Communications Manager” section on
page 5-22 for details.
