About caller ID
This product supports caller ID services offered by most telephone service providers.
Depending on your service subscription, you may see the caller’s number, or the
caller’s name and number that are sent by your telephone service provider after the
first or second ring. Caller ID allows you to see the name, number, date and time
of calls.
Information about caller ID with call waiting
Caller ID with call waiting lets you see the name and telephone number of the caller
before answering the call, even while on another call.
It may be necessary to change your telephone service to use this feature. Contact
your telephone service provider if:
You have both caller ID and call waiting, but as separate services (you may need to
combine these services).
You have only caller ID service, or only call waiting service.
You do not subscribe to caller ID or call waiting services.
There are fees for caller ID services. In addition, services may not be available in
all areas.
This product can provide information only if both you and the caller are in areas
offering caller ID service and if both telephone service providers use compatible
equipment. The time and date, along with the call information, are from the telephone
service provider.
Caller ID information may not be available for every incoming call. Callers may
intentionally block their names and/or telephone numbers. To view caller ID log entries
with numbers between 16 and 24 digits, you must save the entry to the directory (see
page 70).
You can use this product with regular caller ID service, or you can use this product’s
other features without subscribing to caller ID or combined caller ID with call
waiting service.
