The WebRTC API hosted by the W3C supports browser-to browser applications with video chat, voice calling, and file sharing without plugins. Public conception is that the VoIP service is fundamentally flawed. However, Tsahi Levent-Levi at bloggeek.com thinks otherwise. Tsahi, a WebRTC API evangelist, challenges negative outlooks by debasing the top five misconceptions of WebRTC.

If developers can find ways around H.264 & G.722 transcoding issues and building multipoint as an infrastructure, WebRTC is the most reliable voice and video solution for web use that is available, and should be embraced.
