摘要： Disclosed is a method for establishing a communication session. First, the communication session is initiated by a server. Next, a first connection request is generated for a voice call between a first WebRTC device and a second WebRTC device over a WebRTC gateway device. A second connection request including an identifier of first WebRTC device is generated towards a connection management server. Next, an inquiry to the connection management server by the second WebRTC device is generated for determining if a connection request is received from the first WebRTC device, and in that case the communication session including both the first connection for the voice call and a second connection is established.
