Abstract

An automated message distribution system routes digitally-encoded messages via public-switched telephone networks and wide area networks and local area networks to the most desired route. In a preferred embodiment of the invention, digitally encoded messages enter into a local area network, either directly or via a public-switched telephone network, and are sent to their destinations in a distributed manner. The paths or routes are calculating by using a set of customized rules. The customized rules are set to distribute messages evenly among the available paths.
