Billing system and method for database-queried communications services

摘要

A communications system is designed to create a sub-account AMA record for each transaction requested by a caller within a single 900-number call after an initial transaction has been processed. Such sub-account record includes the rate charged for each transaction. Such rate may vary from transaction to transaction and may even negate all charges for an entire call. The sub-account record permits an itemized bill to be created for all transactions processed during such call.
