Abstract:
A method for managing a Voice over IP (VoIP) communication through a packet-based network, wherein said VoIP communication requires the transmission of packets having a header portion and a payload portion, said payload portion containing data associated with said communication and signaling messages utilized to establish, maintain or terminate said VoIP communication, said packets being transmitted from a first node to a second node, said method comprising the steps of:receiving a packet at the first node; if said packet is received at a predefined port of said first node, identifying said packet as containing a signaling message; replacing the signaling message within the payload portion of said packet with an indicators, wherein said indicator comprises fewer bits that said signaling message and functions as a proxy for said signaling message; transmitting the packet to the second node; and restoring the signaling message in the second node by means of the indicator, whereby the bandwidth of the transmission link between said first and second nodes is more efficiently utilized.
