SBX phone wires to pins 3 and 6 (1 and 4 depending on how you look at it) at the jack and out of the SBX control unit, if it is not correct, example 1 and 3 at the control unit end I believe you can get this message on the display of the phone. This occurs when wired to a hybrid circuit, analog extension on pins 2,3.
