About caller ID

This product supports caller ID services that most local telephone service companies provide. There is a fee for this service, and it might not be available in all areas. 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 waiting 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.
