How to Set the Configuration Server

  1. Unplug the power cable from the phone and then plug it back in. The phone will begin its power-up cycle.
  2. 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.

  3. Release # and press 123456789*0#. After you press these keys, the line buttons on the phone flash red, and the phone goes through the factory default process. Do not power down the phone until this process is complete.
