Perform Factory Reset from Phone Keypad

Use these steps to reset the phone to factory default settings using the phone keypad.

Procedure

Step 1

Unplug the phone:

If using PoE, unplug the LAN cable.
If using the power cube, unplug the power cube.

Step 2

Wait 5 seconds.

Step 3

Press and hold # and plug the phone back in.

Step 4

When the light on the Mute button turns off, press 123456789*0# in sequence.

After you press these buttons, the phone goes through the factory reset process.

Caution

Do not power down the phone until it completes the factory reset process, and the main screen appears.

You can reset a phone with any of these operations after the phone has started up. Choose the operation that is appropriate for your situation.

Hello!

The Factory reset procedure is incorrect on 88xx admin guide (Below is Cisco BUG ID)

CSCut29814

Symptom:
The keypad button factory reset procedure in the 8841/51/61 Administration Guide is not accurate.

Conditions:

When attempting the keypad button factory reset procedure documented in the 8841/51/61 administration guide, the phone never reaches the state where "all other lights stay green."

Workaround:

The correct procedure is:

1. Press "#" when you power on the phone
2. You will see the headset,speaker and mute will light on and then light off.
3. When you see only headset and speaker turn on again, please press 123456789*0# in sequence.
4. After you pressed the the first digit "1", you will see speaker turn off.
5. After all the number are input completely in sequence, you will see Mute button turns on to indicate phone begin to do the factory reset.

Hope that helps!!

Charlie
