This document provides an overview of WebRTC and its integration with Asterisk. Some key points: - WebRTC enables real-time communication directly in browsers without additional plugins and works across browsers, OSs, and networks. - It has been adopted as an HTML5 standard by the IETF and W3C and allows audio/video calls, chat, and telepresence using JavaScript APIs. - Asterisk 11 officially supports WebRTC protocols like STUN, ICE, and TURN to enable best connectivity. This allows calls between WebRTC browsers and Asterisk.
