ABSTRACT:
The present invention is a method and apparatus for providing prepaid card service to customers for placing telephone calls without relying on a post-service billing model. A service management computer having access to a card database is connected to the network only by out-of-band connections. A voice response unit or a tone receiver and announcement player in the network are the voice interface with the customer and are provided at the originating switch in the network to eliminate multiple switches from the call path.
