  1. First, determine if the problem is affecting 1 phone or all phones. If it is just the single phone (go to phone issues)
  2. If it is affecting all phones that check the following:
    1.  Locate the main unit (Nortel Processor CLICK HERE to SEE System) It will generally be off the main working area in a storage area.  Typical Dark tan in color.   Check to see if the power
      1. Is the system plugged into a battery backup – Which may be beeping?
      2. Check to see if the system is plugged into a surge stripe and maybe tripped.
      3. Check to see if someone unknowingly unplugged the system
    2.  IF ANY OF THE ABOVE is True – Plug the system into a working outlet  To see if this resolves the problem.

Specific Phone Issues

A,  Check to see if the plug at the Jack or on the Phone has come loose or out of its socket.   It may be a broken clip and by returning it to the position. If the display and phone begin to operate you will need to replace that wire to the phone.

B.  Check the Jack itself to see if the wire was pulled and disconnected wires from the jack components.  Wiggling them or seeing them loose or the jack from the wall.  If so you will need a Telecommunications Technician.

C.  Now check to see if a button is depressed and not functioning. Sometimes keys will get depressed and get caught in the plastics of the phone.  So hit all buttons to see if a button won’t rise up or is stuck down.
