Reset Phone to Factory Defaults
You can clear all locally stored configuration options in a phone from the Phone Settings menu. When you
use the restore to factory default option, all user-defined entries in Network Profiles, Phone Settings, and Call
History are erased.
To erase the local configuration, follow these steps.
Procedure
Step 1
Choose SETTINGS > Phone Settings.
Step 2
Press **2 on the keypad.
The phone briefly displays Start factory reset now?
Step 3
Perform one of the following actions:
•
Press Yes to delete all settings. The phone cycles through normal startup procedures.
•
Press No to cancel the reset.
Step 4
Press SETTINGS > Network Profiles to reconfigure the network settings for your WLAN.
Erasing the local configuration removes network profiles that are set up for the Cisco Unified
Wireless IP Phone to access the WLAN. You must reconfigure the network settings after performing
the reset to enable the phone to access the WLAN.

Create New Configuration File
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. See Cisco
Unified Communications Manager Administration Guide for more information.
