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 Communications Manager, select 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 the

“Adding Users to

Cisco Unified Communications Manager Administration” section on page 7-19

for details.

Step 4

Power cycle the wireless IP phone.

Note

When you remove a phone from the Cisco Unified Communications Manager database, its configuration
file is deleted from the Cisco Unified Communications Manager TFTP server. The directory number
(DN) remains in the Cisco Unified Communications Manager database as an unassigned DN. You can
assign these DNs to other devices or delete them from the Cisco Unified Communications Manager
database. You can use the Route Plan Report to view and delete unassigned reference numbers. Refer to
Cisco Unified Communications Manager Administration Guide for more information.
