Abstract

A system is disclosed for providing enhanced call service and call routing functions from a centralized location on a telephone network line through gateway connections to service providers. A multiple function interface located between a paystation and an originating central office includes a monitoring circuit for monitoring call signals from the paystation, circuits for obtaining coin or card billing information from the paystation and a control circuit for verifying the payment information and selectively directing the call to a service provider to bypass the originating central office. The interface uses an applications platform to communicate with the network and data bases. The platform assists in operations, maintains files and records, and functions as a communications protocol converter for the interface. The platform enables calling customer service preferences to be acertained automatically during call set-up upon receipt of billing information.
