<p>An apparatus and method for increasing available ports on a voice router is provided. A first gateway and a second gateway are assigned a single port number for a data stream, the direction of packet flow is identified to determine a destination gateway. The destination gateway is one of the first and second gateways, depending on the direction of the packet flow. The packets are then forwarded to the destination gateway. The voice router can further consolidate RTCP streams from a plurality of gateways into a single port on the voice router. The voice router comprises a voice connector and a voice switch. In one embodiment, the voice connector dynamically allocates port ranges within the voice switch via a set of allocation commands. The voice connector further accounts for address translation performed by a firewall by sending a connection command to the voice switch.</p> |
