Cisco 79XX - 7942 and 7962 Factory Reset Procedure
Goal
This article provides step by step instructions to help users to perform a factory reset on the Cisco 7972 and 7962 phone models.
Resolution/Steps
- Unplug the power cable from the phone and then plug it back in. The phone begins its power upcycle.
- While the phone is powering up, and before the Speaker button flashes on and off, press and hold #. Continue to hold # until each line button flashes on and off in sequence in amber.
- Release # and press 123456789*0#.
You can press a key twice in a row, but if you press the keys out of sequence, the factory reset will not take place.
After you press these keys, the line buttons on the phone flash red and the phone goes through the factory reset process.
Do not power down the phone until it completes the factory reset process and the main screen appears.
Additional Information
In the case of a VPN capable phone make sure that the phone is behind a CallTower ASA or a CallTower managed Circuit before performing a factory reset. Failure to do so may result in the complete loss of VPN functionality.
