Troubleshooting
My caller ID isn't working.
Caller ID is a subscription service. You must subscribe to this
f
service from your telephone service provider for this feature to
work on your phone.
The caller may not be calling from an area that supports caller ID.
f
Both your telephone service provider and your caller's telephone
f
service provider must use caller ID compatible equipment.
If you subscribe to high-speed Internet service (DSL - digital
f
subscriber line) through your telephone line, you must install a
DSL filter between the telephone line cord and the telephone
wall jack. The filter prevents noise and caller ID problems
resulting from DSL interference. Contact your DSL service
provider for more information about DSL filters.
System does not receive caller ID when on a call.
Make sure you subscribe to caller ID with call waiting features
f
from your telephone service provider. Caller ID features work only
if both you and the caller are in areas offering caller ID service, and
if both telephone service providers use compatible equipment.
System screens all my incoming home calls.
You may have selected the Screen unknown or Screen robot
f
profile setting for Smart call blocker. The telephone asks
callers to announce their names or press the pound key (#). We
recommend that you add the phone numbers of your family
members and friends, and desired businesses to your directory
or allow list, or add their names to the star name list. This will
avoid Smart call blocker to screen their calls.
My telephone does not screen incoming cell calls.
The screening feature of Smart call blocker is applicable to
f
home calls only. All incoming cell calls will get through and
ring. You can block calls of a cell phone number by adding the
number to the block list.
