Possible Cause: Not all calls on Caller ID lines will be displayed. This varies by local
phone company.
What to do: If Caller ID information for a large number of calls is not displayed, contact
your local telephone company.
System Phone in
Combination Extension Does Not Work
Possible Cause 1: System phone is plugged into the wrong jack of the bridging adapter.
What to do: Plug the system phone into the correct jack—see the PARTNER
II
Communications System Installation guide for instructions. (If an MLS-18D is part of the
combination, make sure the second device is plugged directly into it.)

If the system phone works properly, the problem is solved.
If the problem remains, go to Possible Cause 2.
Possible Cause 2: Wrong cord and bridging adapter used to connect the standard phone.
What to do: First, unplug the bridging adapter from the wall jack. Then, unplug the system
phone from the adapter and plug it into the wall jack.
■
If the system phone works properly, either the cord or the adapter must be replaced.
(Use only an AT&T 267F2 bridging adapter.) Call the AT&T Helpline* for details.
Standard Device Does Not Answer
Possible Cause: A standard device (such as a fax machine or answering machine) does
not answer intercom calls or transferred calls because it does not recognize the distinctive
ringing pattern used by the system.
What to do: Change the extension’s setting for
Distinctive Ring (#308) to “Not Active,” so
that the extension uses the same ringing for intercom and transferred calls as it does for
outside calls.

If the device works properly, the problem is solved.
If the problem remains, call the AT&T Helpline* for assistance.
