Abstract
A Carrier Identification Code (CIC) aware private communications network. International calls are placed with a CIC from a station at an originating server and routed over a private network to a connected public network gateway switch located in another country for a far-end hop-off. The public network gateway switch includes a CIC cross reference table with corresponding local CICs. The public network gateway switch replaces the original CIC with a corresponding local CIC from the cross reference table. Then, the call egresses from the public network gateway switch to a corresponding selected carrier network and connects to the called party on the public communications network.
