So how does this fit with SIP, which I’ve spent much of the last 10+ years working on? SIP or Session Initiation Protocol is the IETF protocol for establishing voice and video sessions over the Internet. SIP is used all over the Internet today, and in private networks. It is used by service providers for VoIP (Voice over IP) networks, and it is used by enterprises for their internal PBX (Private Branch Exchange) networks. It is also in a number of applications and services including Skype In and Out and even Apple’s Facetime (kind of).
This topic will continue to be discussed in the standards bodies, and also in next month’s ITEXP Internet Telephony Expo. I’m excited to be giving an all-day SIP Tutorial with Henry Sinnreich in which we will introduce and teach SIP and also the principles behind the RTCWEB effort and how SIP and RTCWEB relate. You can find out more about the tutorial and register using this link.
One of the other hot topics of RTCWEB is security, and I have written and spoken out about the need for privacy – protection against eavesdropping on voice and video communication. A media security protocol such as ZRTP would be an excellent choice, but there are other options. Unfortunately, there is a contingent that wants to permit unencrypted voice and video media from the browser. But that is a topic for another day…
Hope to see some of you in Austin, Texas at the SIP Tutorial on September 15. 2011!
