Abstract
Embodiments include providing reliable Session Initiation Protocol (SIP) signaling for Web Real Time Communications (WebRTC) interactive flows, and related methods, systems, and computer-readable media. In one embodiment, a method for providing reliable SIP signaling for WebRTC interactive flows comprises establishing, via a stateless SIP user agent executing on a first web server, a WebRTC interactive flow between a WebRTC client executing on a computing device and a remote endpoint. The method further comprises receiving, by the WebRTC client, a call state from the stateless SIP user agent, the call state indicating a current state of the WebRTC interactive flow. The method also comprises storing, by the WebRTC client, the call state. In this manner, the call state of the WebRTC interactive flow may be accessible for restoring the WebRTC interactive flow in the event of an unexpected termination of the WebRTC client and/or the stateless SIP user agent.
