Our Ups and Downs with WebRTC
For someone who has struggled with SIP interoperability for the past 15 years, WebRTC has an earthshaking impact. Instead of arguing about SIP headers, UDP and RFC, WebRTC makes it possible for the PBX vendor to write software for clients. The interoperability is essentially JavaScript, which has very little room for interpretation (compared to SIP). This means we can offer all the features of the PBX in the browser, without any interop problems, on practically any platform that's out there. This will ultimately make SIP softphones superfluous.
