发明名称 TELEPHONE BILLING SYSTEM
摘要 A method and apparatus for billing a customer for a service that is assessed independent of the calling duration or the per call cost. A service is billed and delivered during a call without the called party being present to receive the call and without operator-assisted verification. A calling party can order a service that is not delivered through the call itself.
