Startup Problems
Solution
If you use DNS to access the TFTP server or Cisco Unified Communications Manager, you must ensure that
you specify a DNS server. See
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,
the configuration file may be corrupted.
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 is added to the server or if autoregistration is enabled. Review the information and procedures in
Unified Communications Manager Phone Addition Methods, on page 50
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
Address Determination, on page
If the phone is already in the Cisco Unified Communications Manager database, the configuration file may
be damaged. See
Cisco Unified IP Phone 8961, 9951, and 9971 Administration Guide for Cisco Unified Communications Manager
