Patent Images
1. A voice router for interfacing a first network and a second network, the voice router comprising:
- a packet translation module configured to communicate with the first network on a first port number, and configured to communicate with the second network on the first port number, and configured to receive a packet on the first port number and to forward the packet from the first port number;
a packet direction module coupled to the packet translation module configured to determine a direction in which to forward the packet; and
a port initialization module configured to assign the first port number to the first and second networks, and configured to determine a port number range corresponding to network type information for the first and second networks.

Abstract
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.

6. A method for increasing a quantity of available port numbers on a voice router, the method comprising:
-
determining a port number range corresponding to network type information for a first network and a second network, the first network having a first gateway and the second network having a second gateway; assigning a first data stream from the first gateway and the second gateway to a first port number; identifying a direction for packets of the first data stream to determine a destination gateway, wherein the destination gateway is one of the first and second gateways; and forwarding the packets to the destination gateway. - View Dependent Claims (7, 8, 9, 10, 11)
