Abstract
A telephone apparatus for connection to central office equipment to receive a caller ID signal therefrom and having an operating mode in which line current is less than a threshold at which off-hook state is detected, the line current drawn in said mode being sufficient to allow reception and processing of the caller ID signal. In this way, the telephone apparatus can receive and process the caller ID signal, and so can determine whether the call can be accepted, without the central office equipment recognizing the apparatus as having gone off-hook (i.e. having already accepted the call).
