Abstract

A call agent (1004) for routing calls through a data packet network (1016) communicates with or includes an address translation module (1008) that determines the address routing for a call and that enables the call agent (1004) to setup the call. The address translation module (1008) is formed to receive information about the source of the call and to determine how to route the call. Then, the address translation module (1008) communicates with the call agent (1004) to enable it to complete the call routing. Even if a called party cannot be reached purely by way of the Internet (1016), the address translation module is able to determine a media or signaling gateway to which the call can be routed by way of the Internet (1016) and from which a call may be generated over a public switched telephone network.
