Cisco Unified Communications Manager and TFTP Services Are Not Running
Problem
If the Cisco Unified Communications Manager 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 Unified Communications Manager 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 Start Service, on page 172.
Configuration File Corruption
Problem
If you continue to have problems with a particular phone that other suggestions in this chapter do not resolve,
the configuration file may be corrupted.
Solution
Create a new phone configuration file.

Cisco Unified Communications Manager Phone Registration
Problem
The phone is not registered with the Cisco Unified Communications Manager
Solution
A Cisco IP Phone can register with a Cisco Unified Communications Manager server only if the phone is
added to the server or if autoregistration is enabled. Review the information and procedures in Phone Addition
Methods, on page 56 to ensure that the phone is added to the Cisco Unified Communications Manager
database.
To verify that the phone is in the Cisco Unified Communications Manager database, choose Device > Phone
from Cisco Unified Communications Manager Administration. Click Find to search for the phone based on
the MAC Address. For information about determining a MAC address, see Determine the Phone MAC Address,
on page 55.
If the phone is already in the Cisco Unified Communications Manager database, the configuration file may
be damaged. See Configuration File Corruption, on page 162 for assistance.
