We’ve talked before about the revolutionary importance of WebRTC, because it brings the principles of the open web to voice, video, screensharing, and other applications that were traditionally closed off to fast innovation. This revolution has been led not by old-style telcos but by web and mobile companies, especially the developers of the Google Chrome and Mozilla Firefox browsers.
Until recently, both Microsoft and Apple have been standing on the sidelines as this revolution unfolded. Thankfully that’s starting to change, as Microsoft adds these capabilities to its upcoming Edge browser. (Apple, however, is still late to the party.)
There’s a twist to this story, though, because Edge supports an object-oriented flavor of WebRTC called ORTC, which most observers expect will eventually become WebRTC 1.1 or 2.0 or something. :-)
Thus we have a conundrum: in video conferencing apps like our Talky service, cross-browser calls work fine right now because both Chrome and Firefox support WebRTC. But adding Edge to the mix doesn’t automatically result in cross-browser calls to Edge users, since the signaling methods involved have different syntax even though the semantics are the same.
