ABSTRACT:
A communications system is arranged to route a database-queried call (900-number or 800-number call) to a subscriber (pay-per-call sponsor or 800-number customer), and to deliver to the subscriber information identifying the call as a database-queried call, as opposed to a switched-line or POTS call.
