Identifying Error Messages
As the phone cycles through the startup process, you can access status messages
that might provide you with information about the cause of a problem. See the
“Status Messages Screen” section on page 7-4 for instructions about accessing
status messages and for a list of potential errors, their explanations, and their
solutions.
Registering the Phone with Cisco Unified Communications Manager
A Cisco Unified IP Phone can register with a Cisco Unified Communications
Manager server only if the phone has been added to the server or if
auto-registration is enabled. Review the information and procedures in the
“Adding Phones to the Cisco Unified Communications Manager Database”
section on page 2-12 to ensure that the phone has been added to the
Cisco Unified Communications Manager database.
To verify that the phone is in the Cisco Unified Communications Manager
database, choose Device > Find from Cisco Unified Communications Manager
Administration to search for the phone based on its MAC Address. For
information about determining a MAC address, see the “Determining the MAC
Address of a Cisco Unified IP Phone” section on page 2-19.
If the phone is already in the Cisco Unified Communications Manager database,
its configuration file may be damaged. See the “Creating a New Configuration
File” section on page 9-7 for assistance.
Checking Network Connectivity
If the network is down between the phone and the TFTP server or
Cisco Unified Communications Manager, the phone cannot start up properly.
Ensure that the network is currently running.
