ABSTRACT:
This invention provides a path establishment device and method for establishing a path for a telecommunications call. In a preferred embodiment, the path establishment device of this invention includes an originating call processor in communication with an originating telecommunications network and a packet-based telecommunications network, a terminating call processor in communication with the packet-based telecommunications network and a public telecommunications network, and means for establishing a communication path from the originating telecommunications network through the packet-based telecommunications network to a destination served by the public telecommunications network. The path establishment device and method of the present invention thus provides, among other advantages, for the use of a potentially less expensive packet-switched telecommunications network as a long distance carrier between two public switched telecommunications networks.
