Possible Cause 5: The telephone may be defective.
What to do: Test the telephone by replacing it with a similar telephone that you
know is working properly.
If the replacement telephone rings, then replace it with the original
telephone and check again. If the original telephone still does not ring,
then the original telephone may be defective. Call the AT&T Helpline at
1 800 628-2888.
If the replacement telephone does not ring, there may be a problem with
the system wiring or the control unit. To test one wiring possibility, go to
Possible Cause 6.

easy reach. If you do not have a stable ladder or other proper equipment,
do not proceed; wait for the AT&T technician.
Possible Cause 6: The wiring is faulty somewhere in the system.
What to do: Test the control unit module and jack where the telephone is
plugged in.
Identify the port where the non-functional telephone is connected.
Identify a second port in the same module connected to a functional
telephone and unplug the jack from the module. Plug the jack for the
non-working phone into the extension jack that is now open. If the
telephone works, call the AT&T Helpline at 1 800 628-2888.
