• If you subscribe to high-speed Internet service
(ADSL - digital subscriber line) through your
telephone line, you must install a ADSL ilter
between the telephone line cord and the telephone
wall jack. The ilter prevents noise and Calling
Number Display problems resulting from ADSL
interference. Contact your ADSL service provider for
more information about ADSL ilters.
My telephone does not receive Calling Number
Display when on a call.
• Make sure you subscribe to Calling Number Display
with call waiting features from your telephone
service provider. Calling Number Display feature
works only if both you and the caller are in areas
offering Calling Number Display service, and if
both telephone service providers use compatible
equipment.
I subscribe to a nontraditional telephone service that
uses my computer to establish connections, and my
telephone doesn't work.
• Make sure your computer is powered on.
• Make sure your Internet connection is working
properly.
If you are using a irewall, it may prevent access
•
to your nontraditional telephone service provider.
Contact your service provider for more information.
