Patent number: 9350699Abstract: 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.Type: GrantFiled: July 24, 2014Date of Patent: May 24, 2016Assignee: XMedius Solutions Inc.Inventors: Sébastien Boire-Lavigne, Richard Collette, Sébastien Lalonde, Éric Malenfant
