Cisco CallManager and TFTP Services Are Not Running
Problem
If the Cisco CallManager or TFTP services are not running, phones may not be able to start up properly. In
such a situation, it is likely that you are experiencing a systemwide failure, and other phones and devices are
unable to start up properly.
Solution
If the Cisco CallManager service is not running, all devices on the network that rely on it to make phone calls
are affected. If the TFTP service is not running, many devices cannot start up successfully. For more
information, see
Configuration File Corruption
Problem
If you continue to have problems with a particular phone that other suggestions in this chapter do not resolve,

Solution
Create a new phone configuration file. See
Cisco Unified Communications Manager Phone Registration
Problem
The phone is not registered with the Cisco Unified Communications Manager
Solution
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
Cisco Unified Communications Manager Phone Addition Methods
to the Cisco Unified Communications Manager database.
To verify that the phone is in the Cisco Unified Communications Manager database, choose Device > Phone >
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
Determination.
If the phone is already in the Cisco Unified Communications Manager database, its configuration file may be
damaged. See
