Troubleshooting
My caller ID isn't working.
Caller ID is a subs�ription servi�e. You must subs�ribe to this
servi�e from �our telephone servi�e provider for this feature
to work on �our phone.
The �aller must be �allin� from an area that supports �aller ID.
�oth �our and �our �aller's telephone servi�e providers must
use �aller ID �ompatible equipment.
If �ou subs�ribe to hi�h-speed Internet servi�e (DSL - di�ital
subs�riber line) throu�h �our telephone line, �ou must install a
DSL filter between the telephone line �ord and the telephone
wall ja�k. The filter prevents noise and �aller ID problems
resultin� from DSL interferen�e. Conta�t �our DSL servi�e
provider for more information about DSL filters.
System does not receive caller ID when on a call.
Make sure �ou subs�ribe to �aller ID with �all waitin� features
from �our telephone servi�e provider. Caller ID features work
onl� if both �ou and the �aller are in areas offerin� �aller
ID servi�e, and if both telephone servi�e providers use
�ompatible equipment.
I subscribe to a nontraditional telephone service that uses
my computer to establish connections, and my telephone
doesn't work.
Make sure �our �omputer is powered on.
Make sure �our Internet �onne�tion is workin� properl�.
Make sure that the software is installed and runnin� for �our
nontraditional telephone servi�e.
Make sure to plu� �our �S� telephone adapter into a
dedi�ated �S� port on �our �omputer. Do not plu� it into a
multiple port �S� hub (�S� splitter) that is not powered.
