Troubleshooting
My caller ID features
are not working
properly
Caller ID is a subscription service. You must
subscribe to this service from your telephone service
provider for this feature to work on your telephone.
The caller might not be calling from an area that
supports caller ID.
Both your and the caller’s telephone service
providers must use equipment compatible with
caller ID service.
Make sure you select
ALL CALLS
in
CALL LOG
(see
Feature summary
on page 15) to set the telephone
to record caller ID information in the call history.
If you select
NEW CALL FIRST
in
CALL LIST ORDER
,
the telephone first shows the new (unreviewed)
caller ID entries then entries starting with the most
recent call in the call history. If you select
BY TIME
,
the telephone shows the caller ID entries starting
with the most recent call in the call history (see
Feature summary
on page 15).
Make sure the area codes are set correctly in the
telephone (see
Set home area code
on page 19
and
Set local area code
on page 19).
Reset the telephone. See
Common cure for
electronic equipment
on page 58.
If you subscribe to high-speed Internet service
(digital subscriber line - DSL) through your
telephone line, you must install a DSL filter between
the telephone line cord and the telephone wall jack
(see
Telephone installation
on page 7). The filter
prevents noise and caller ID problems caused by
DSL interference. Please contact your DSL service
provider for more information about DSL filters.
