Panasonic Kx-ta 824 door phone

When I attempt to reach the door phone I get what sounds like a busy signal or the signal that the phone would produce when you dial an extension which is not connected. I have checked the door phone controller and it appears to be connected correctly. It does not give a busy signal when you dial the code for the door unlatch.
