Caller ID history
Information about caller ID with call waiting
This product has a caller ID function with call
waiting feature which works with service from
your local telephone company.
Caller ID with call waiting lets you see the name
and telephone number of the caller before
answering the telephone, even when on another
call.
It may be necessary to change your telephone
service to use this feature. Contact your telephone
company if:
• You have both caller ID and call waiting, but as
separate services (you may need combined service).
• You have only caller ID service, or only call wait-
ing service.
• You do not have any caller ID or call waiting
services.
This product can be used with regular caller ID
service, or this product’s other features can be
used without subscribing to either caller ID or
combined caller ID with call waiting service. There
are fees for caller ID services, and they may not
be available in all areas.
Depending on your service, you may see the caller’s
number or the caller’s name and number. This product
can provide information only if both you and the
caller are in areas offering caller ID service and if
both telephone companies use compatible equipment.
The time and date are sent by the telephone company
along with the call information.
