Appendix
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 (page 10). The lter
prevents noise and caller ID problems resulting from DSL interference.
Please 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 works only if both you and
the caller are in areas oering caller ID service, and if both telephone
service providers use compatible equipment.
System screens all my incoming calls.
f You may have set Smart call blocker to screen calls without numbers
and uncategorized calls. 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 (see page 62) or Allow list (see page 93), or add their
names to the Star name list (see page 98). This will avoid Smart call
blocker to screen their calls.
f To turn Smart call blocker o, see Set Smart call blocker on/o on page
85.
While screening a call, the telephone suddenly stops screening and
connects to the call.
f Another handset may have picked up the screening call.
f If you have other telephone system sharing the same telephone line,
and someone picks up the call on the other telephone system while the
screening is in progress, the screening process will be terminated and
connect you to the caller.
My telephone block calls from someone I know.
f You may have saved the caller’s number to your block list. To remove the
number from the block list. See Delete a block entry on page 92.
