Creating a New Configuration File
If you continue to have problems with a particular phone that other suggestions in
this chapter do not resolve, the configuration file might be corrupted.
To create a new configuration file, follow these steps:
Procedure
Step 1 From Cisco Unified CallManager, select Device > Phone > Find to locate the
phone experiencing problems.
Step 2 Choose Delete to remove the phone from the Cisco Unified CallManager
database.
Step 3 Add the phone back to the Cisco Unified CallManager database. See the “Adding
Users to Cisco Unified CallManager” section on page 6-22 for details.
Step 4 Power cycle the wireless IP phone.
Note When you remove a phone from the Cisco Unified CallManager database, its
configuration file is deleted from the Cisco
Unified CallManager TFTP server.
The directory number (DN) remains in the Cisco
Unified CallManager database
as an unassigned DN. You can assign these DNs to other devices or delete them
from the Cisco
Unified CallManager database. You can use the Route Plan Report
to view and delete unassigned reference numbers. Refer to Cisco
Unified CallManager Administration Guide for more information.
