Reverse billing of internet telephone calls

Abstract

In recent years, the world-wide packet data network, commonly known as the Internet, has grown exponentially. The data network now reaches virtually all businesses, most schools and an increasing number of homes. To provide an alternative to all or portions of the carrier-based telephone network, a number of companies have developed equipment and software that enable voice telephone-like communications via the Internet. Severs are now coming on line, which enable calls over the Internet to go off-net to end user stations still coupled to the local telephone network. A number of situations arise where a telephone service subscriber wants to allow callers to call the subscriber's equipment and have part or all of the communication charges billed to and paid by the subscriber. The invention enables such billing to the called party, for calls routed partially or entirely via the Internet. In one example, a caller with a multimedia PC and Internet access uses the subscriber's Internet address plus the subscriber's telephone number. The address identifies a gateway serving the subscriber, and the gateway places a telephone call to the subscriber's telephone. The network accumulates all billing information in records for application against the called subscriber's account.
