Abstract: A conditional purchase offer (CPO) management system is disclosed for receiving and processing CPOs for telephone calls from calling parties. The CPO management system processes the CPO to determine whether one or more long distance carriers is willing to accept a given CPO and complete a telephone call in accordance with restrictions defined by the calling party. If accepted, the CPO management system binds the calling party on behalf of the accepting interexchange carrier, to form a legally binding contract. A calling party can submit a CPO for an individual telephone call, a package of calls to one or more called parties, or for a contract to provide telephone service for a predefined period of time. The conditions defined by the calling party may include the telephone number to be called, the maximum price, one or more preferred carriers, if any, as well as any time limitations, such as a particular time-of-day or minimum call duration.

Abstract: Authorizing a billing by a billing system of a telephone network, to a subscriber, for a service requested over the Internet, using a calling card. A line information database is accessed to obtain the telephone number corresponding to the calling card identifier, and the service is billed to that number. This puts existing telephone billing system and calling card infrastructure to a new use and provides a payment or authorization method that is easy to use and to deploy and bring to market on a large scale.

Abstract: A method and system for creating and sending call disposition messages. When a calling card call is validated by the telephone network which issued the card, the card issuing network can request a call disposition message. In response to validation of the call, a billing detail record is generated and stored. When the call is completed. an operator service record is generated. The operator service record and its corresponding billing detail record are matched with each other, then merged to form a merged operator services record. The merged operator services record is processed to add pricing information. If the card issuing network had requested a call disposition message, the merged operator services record is sent to a gateway coupled to the card issuing network where it is reformatted to create a call disposition message. The call disposition message is then sent to the card issuing network.
