Abstract

Method and system for calling card validation hubbing provides a hubbed architecture for communicating validation messages relating to a calling card number to be validated between a telecommunications network which accepts a calling card call and the telecommunications network which issued the card. The hubbing system provides transport links and protocol translation between ANSI SS7, ITU CCS7 and X.25 for each telecommunications network which is attached. When an attached telecommunications network accepts a calling card call, an authorization request including calling card number is sent to the hubbing system, translated to the protocol used by the card issuing network and transported to the card issuing network for validation. Also communicated are request responses, which indicate success or failure of validation, and call disposition messages, which provide a timely estimate of call duration and charges.
