Troubleshooting and Maintenance
• When you remove a phone from the Cisco Unified Communications Manager database, its
Note
configuration file is deleted from the Cisco Unified Communications Manager TFTP server. The
phone's directory number or numbers remain in the Cisco Unified Communications Manager database.
They are called "unassigned DNs" and can be used for other devices. If unassigned DNs are not used
by other devices, delete them from the Cisco Unified Communications Manager database. You can
use the Route Plan Report to view and delete unassigned reference numbers. See Cisco
Unified Communications Manager Administration Guide for more information.
• Changing the buttons on a phone button template, or assigning a different phone button template to
a phone, may result in directory numbers that are no longer accessible from the phone. The directory
numbers are still assigned to the phone in the Cisco Unified Communications Manager database,
but there is no button on the phone with which calls can be answered. These directory numbers
should be removed from the phone and deleted if necessary.
To create a new configuration file, follow these steps:
Procedure
Step 1
From Cisco Unified Communications Manager, choose Device > Phone > Find to locate the phone experiencing
problems.
Step 2
Choose Delete to remove the phone from the Cisco Unified Communications Manager database.
Step 3
Add the phone back to the Cisco Unified Communications Manager database. See
Communications Manager Phone Addition Methods, on page 38
Step 4
Power cycle the phone.
