Using Web Services for WebRTC signaling interoperability

WebRTC-based applications are assumed to be based mostly on peer-to-peer communication, where an instance of the application is talking to another instance. However, this is not always the case: a WebRTC-based application communicating with a legacy VoIP device or Media Server like a Video Conference Server is also very common. The ability to make both types of communications (WebRTC to WebRTC and WebRTC to Legacy VoIP) is a differentiating factor for a WebRTC product. This paper makes a proposal on how this could be achieved on the signaling layer by leveraging an industry standard method such as the RESTful Web Services.
