1. A method for embedding network type information within a packet header, the method comprising:
- identifying a first network type for a first gateway;
embedding a first identifier corresponding to the first network type within a packet header;
identifying a second network type for a second gateway;
embedding a second identifier corresponding to the second network type within the packet header; and
transmitting the packet on a connection between the first gateway and the second gateway.

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.

4. 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; and a packet direction module coupled to the packet translation module configured to determine a direction in which to forward the packet. - View Dependent Claims (5, 6, 7, 8)

9. A method for increasing a quantity of available port numbers on a voice router, the method comprising:
-
assigning a first data stream from a first gateway and a 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 (10, 11, 12, 13, 14)
