Reset the 7940 and 7960 IP Phones to the Factory Default

In order to perform a factory reset of a phone if the password is set,
complete these steps:

1. Unplug the power cable from the phone, and then plug in the cable
   again.

   The phone begins its power up cycle.

2. Immediately press and hold # while the Headset, Mute, and Speaker
   buttons flash in sequence.

   Release # after the Speaker button is no longer
   lit.

   The Headset, Mute, and Speaker buttons flash in sequence in order
   to indicate that the phone waits for you to enter the key sequence for the
   reset.

3. Press 123456789*0# within 60 seconds after the
   Headset, Mute, and Speaker buttons begin to flash.

   If you repeat a key within the sequence, for example, if you press
   1223456789*0#, the sequence is still accepted and the phone resets.

   If you do not complete this key sequence or do not press any keys,
   after 60 seconds, the Headset, Mute, and Speaker buttons no longer flash, and
   the phone continues with its normal startup process. The phone does not reset.

   If you enter an invalid key sequence, the buttons no longer flash,
   and the phone continues with its normal startup process. The phone does not
   reset.

   If you enter this key sequence correctly, the phone displays this
   prompt:

   Keep network cfg? 1 = yes
   2 = no

4. In order to maintain the current network configuration settings for
   the phone when the phone resets, press 1. In order to reset
   the network configuration settings when the phone resets, press

   2.

   If you press another key or do not respond to this prompt within 60
   seconds, the phone continues with its normal startup process and does not
   reset. Otherwise, the phone goes through the factory reset process.
