For analog telephone service subscribers, an apparatus and a method is provided for displaying a caller's originating number and/or the current time of day on the subscriber's incoming call line identification equipment. The subscriber's originating telephone number is obtained from a database within the telephone switching system providing POTS service to the subscriber. The time of day is obtained from a real-time clock within or in communication with the telephone switching system. Data is preferably transmitted to the subscriber's equipment by analog frequency shift keyed protocol.
