General Troubleshooting Information
For information about using the Trace Route option, see the “Using the Trace
Route Option on the Cisco Wireless IP Phone” section on page 9-18.
Erasing the Local Configuration
You can clear all locally stored configuration options in a phone by using the
Phone Settings menu. When you use the restore to factory default option, all
user-defined entries in Speed Dial, Profiles, Phone Settings, and Call History are
erased, but the Phone Book entries remain.
Note You can also use the Cisco 7920 Configuration Utility to erase the local
configuration.
To erase the local configuration by using the phone menu, use these steps.
Procedure
Step 1 Press Menu > Phone Settings > Factory Default.
The phone displays “Restore to Default?”
Step 2 Press the OK softkey. All settings are deleted.
The phone cycles through normal startup procedures.
Step 3 Press Menu > Network Config to reconfigure the network settings for your
WLAN.
Caution Erasing the local configuration removes user-defined changes in speed dial, phone
settings, and profiles that are made locally on the Cisco Wireless IP Phone. All
call history entries are removed, and all network settings are set back to the default
values. Only the personal phone book entries are retained. You must reconfigure
the network settings for the phone to access the network again.
