Patent

CA 2751605

A system and method for traversing a firewall for a voice-over-IP session or other communication session uses four main components: a relay agent, and NAT 30Agent, a SIP proxy and a application server. The SIP proxy is located in the public network and SIP signaling messages are routed through the SIP proxy. The sever opens ports in the firewall for signaling between the SIP proxy and the relay agent behind the firewall. The application server also opens ports in the firewall for media traffic. The NAT 30Agent disposed in the path from the firewall to the Internet filters media packets and changes the public source address of the media packets to a predetermined address associated with the open media port.

L'invention porte sur un système et un procédé de traversée d'un pare-feu, pour une session de voix sur IP ou autre session de communication, qui utilisent quatre composants principaux : un agent de relais, un agent de traduction d'adresse réseau (NAT) (30), un mandataire SIP et un serveur d'application. Le mandataire SIP se trouve dans le réseau public et des messages de signalisation SIP sont routés par l'intermédiaire du mandataire SIP. Le serveur ouvre des ports dans le pare-feu pour une signalisation entre le mandataire SIP et l'agent de relais derrière le pare-feu. Le serveur d'application ouvre également des ports dans le pare-feu pour un trafic multimédia. L'agent NAT (30) placé dans le trajet allant du pare-feu à l'Internet filtre des paquets multimédias et change l'adresse source publique des paquets multimédias en une adresse prédéterminée associée au port multimédia ouvert.
