Abstract:
A system, method and computer-readable medium by-passing the public switched telephone network when routing a call from a carrier network to an enterprise network are provided. A carrier gateway server is communicatively coupled with an enterprise gateway server. The enterprise gateway server is adapted to publish direct inward dial numbers assigned to enterprise extensions to the carrier gateway server. Once published, call setups originated in the carrier network may be routed directly to an enterprise network having a terminal assigned the dialed number of the call setup. Advantageously, the carrier network operator does not incur any inter-connect fee from any public switched network operator.
