Create a New Phone Configuration File
When you remove a phone from the Cisco Unified Communications Manager database, the configuration file
is deleted from the Cisco Unified Communications Manager TFTP server. The phone 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 these DNs from
the Cisco Unified Communications Manager database. You can use the Route Plan Report to view and delete
unassigned reference numbers. For more information, see the documentation for your particular Cisco Unified
Communications Manager release.
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 the phone has no button
on the phone with which calls can be answered. These directory numbers should be removed from the phone
and deleted if necessary.
Procedure
Step 1
From Cisco Unified Communications Manager, choose Device > Phone and click Find to locate the phone
that is experiencing problems.
Step 2
Choose Delete to remove the phone from the Cisco Unified Communications Manager database.
