Troubleshooting
Caller ID isn’t
working.
Caller ID is a subscription service. You must subscribe to
this service from your telephone service provider for this
feature to work on your telephone.
If you subscribe to high-speed Internet service (digital
subscriber line - DSL) through your telephone line, you
must install a DSL filter between the telephone line
cord and the telephone wall jack (page 5). The filter
prevents noise and caller ID problems caused by DSL
interference. Please contact your DSL service provider
for more information about DSL filters.
Your caller must be calling from an area that supports
caller ID.
Both your and your caller’s telephone service providers
must use equipment that is compatible with caller ID.

No caller ID
information
while on a call.
Make sure your telephone service provider provides
caller ID information while you are on a call. This is
sometimes known as caller ID on call waiting or type 2
caller ID.
The telephone cannot display the information if another
telephone on the same line is in use. Make sure all
extensions are on hook.

A home area code must be programmed. If you try to
display dial before entering a home area code, you

the code or enter 000 if you dial 10 digit telephone
numbers. Then press OPTIONS.
