My caller ID isn’t working.
f Caller ID is a subscription service. You must subscribe to this
service from your telephone service provider for this feature to
work on your phone.
f The caller may not be calling from an area that supports caller ID.
f Both your telephone service provider and your caller’s telephone
service provider must use caller ID compatible equipment.
f If you subscribe to high-speed Internet service (DSL - digital
subscriber line) through your telephone line, you must install a
DSL lter between the telephone line cord and the telephone
wall jack. The lter prevents noise and caller ID problems
resulting from DSL interference. Contact your DSL service
provider for more information about DSL lters.
System does not receive caller ID when on a call.
f Make sure you subscribe to caller ID with call waiting features
from your telephone service provider. Caller ID features work only
if both you and the caller are in areas oering caller ID service, and
if both telephone service providers use compatible equipment.
My telephone block calls from someone I know.
f You may have saved the caller’s number in your block list. If yes,
remove the number from the list.
I subscribe to a nontraditional telephone service that uses my
computer to establish connections, and my telephone doesn’t
work.
f Make sure your computer is powered on.

nontraditional telephone service.
