Abstract: A Telecom Access Billing System provides the capability for a communication carrier service provider to substantially automate the payment to other communication carrier service providers for the use of their services and equipment. Billed charges are received in a variety of forms from the communication carrier service providers which are providing the services. A processor uploads the information, checks its integrity, and converts it to a format in which it can be further processed. Once the information has been uploaded and converted, a validation process is performed in which the individual items of the bill are checked as to whether the rate information charged by the communication carrier service providers matches the rates which have been either negotiated or established by a third party. Any discrepancies noted in this comparison process are included in a dispute report which is associated with the invoice on which the billed charges appear.
