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 # and while the Headset, Mute, and Speaker buttons begin to flash in sequence, release #. 
    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.

 

Option 2 (if the Line lights flash in sequence after holding #, use this sequence)Power off the phone (if using inline power, just remove the ethernet).

  1. 5. Hold the # key down.
  2. Power on the phone while still holding down the # key.
  3. When the line buttons scroll down orange, you can take your finger off the hash button
  4. Press the following buttons: 3491672850*#
  5. The line buttons should continue to scroll, but now they should be red
  6. After about 60sec, this will change to green, and the phone should the boot up correctly

          Note: this will take between 5 and 10 minutes for the firmware to reinstall.  The screen will be completely blank during this time.
