Single-Line Phones Ring Back after Completed Call

NOTE:
If only one MLX-20L is available, plug that telephone into a jack that you know is
working and then retest. If the telephone rings for incoming calls, then the
original jack may be faulty; call the AT&T Helpline at 1 800 628-2888. If the
telephone still does not ring, there may be a problem with the system wiring or
the control unit; call the AT&T Helpline at 1 800 628-2888.
If the replacement telephone rings for incoming calls, then replace it with
the original telephone and check again. If the original telephone still does
not ring for incoming calls, then the original telephone may be defective.

What to do: Test the telephone by replacing it with a similar telephone that you
know is working properly.

original telephone and check again. If the original telephone still rings
back, then the original telephone may be defective. Call the AT&T
Helpline at 1 800 628-2888.
