CA 2662529

A method for half-duplex communication between a first Session Initiation Protocol (SIP) Communication Device having access to a computer network, and a second SIP Communication Device having access to that computer network. The method comprises the steps of establishing a first Real-Time Transport Protocol (RTP) channel between the first SIP Communication Device and a first computer on the network, and establishing a second RTP channel between the second SIP Communication Device and a second computer on the network, then establishing a communication channel between the first computer and the second computer. Transmission access on the commumcaion channel between the first and second computers is then limited to a maximum of one computer at a time.

Cette invention concerne un procédé pour une communication semi-duplex entre un premier dispositif de communication à protocole d'ouverture de session (SIP) ayant accès à un réseau informatique, et un second dispositif de communication SIP ayant accès à ce réseau informatique. Le procédé comprend les étapes consistant à établir un premier canal à protocole de transport en temps réel (RTP) entre le premier dispositif de communication SIP et un premier ordinateur sur le réseau, à établir un second canal RTP entre le second dispositif de communication SIP et un second ordinateur sur le réseau, puis à établir un canal de communication entre le premier ordinateur et le second ordinateur. L'accès de transmission sur le canal de communication entre le premier et le second ordinateur est ensuite limité à un maximum d'un ordinateur à la fois.
