Abstract
Long distance communications service between two communications systems is established by using a wide area packet switched network, for example the Internet, to transport signaling data and digitized communication traffic. Each communications system uses an interface server to encapsulate communication traffic and signaling data into data packets suitable for transport over the wide area packet switched network. The interface server accesses a routing and administration database to determine a destination address of a destination interface server based on the area code of the called number. Upon receiving the destination address and a prescribed bandwidth from the routing and administration database, the telephony server inserts the destination address to the data packets for a destination server for a second communications system. The packets are then output to the Internet, and subsequently routed to the destination server serving as an interface for the second communications system. Routing of packets is preferably performed using reserved virtual paths to guarantee quality of service.
