My phone is displaying "No SIP reg" and is unusable


My wireless phone is displaying "No SIP reg" and I am unable to receive nor make calls.



  1. Locate the base of the wireless phone.
  2. Unplug the power cable from the base.
  3. Unplug any other cable from the base if there are any.
  4. Wait 5 seconds.
  5. Plug all the cables back and wait for the phone to reboot.
