VUC500: A Special Event Featuring Dr. Henning Schulzrinne

Friday, August 1st will see Dr. Henning Schulzrinne appearing as our featured guest for the 500th(!) edition of the VoIP Users Conference. While presently the CTO of the FCC, Dr. Schulzrinne has along history as a pioneer in the field of real-time communications over IP networks. He is responsible for the creation of such protocols as RTP and RTSP, and co-creator of SIP. He is a co-chair of the Internet Technical Committee of the IEEE Communications Society. His name appears on numerous RFCs.

In 2013 Dr. Schulzrinne was inducted into the Internet Hall Of Fame. The following clip is his acceptance speech from that ceremony. I offer it in the hope that it will help inspire some good questions.

The technical part of this weeks exercise will involve the use of Jitsi Video Bridge (http://jitsi.org) to host the call instead of our usual G+ Hangout. Thus we’ll be taking a pure, open source, WebRTC approach to things. Given a limited number of seats on the Jitsi video bridge they are by invitation only.

To allow more people to watch the call the Jitsi Video Bridge feed will be live streamed to our YouTube channel*. http://youtu.be/-pfXBE2POxo

Jitsi Video Bridge has a newly implemented ability to dial out to a SIP URI. This is how we’ll be interconnecting with ZipDX. Since both JVB and ZipDX support  the Opus codec that will be a good quality connection.

Interactive, if audio-only, participation in the call will be possible by connecting to ZipDX via SIP URI (200901@conf.zipdx.com)

The audio will also be streamed live via Mixlr. http://mixlr.com/voipusers/

A big thank you goes out to Emil Ivov and the Jitsi team for setting this up!

*The mechanics of exactly how we’re feeding YouTube from JVB I will likely describe in a future post.

New Skype Alternatives for Internet Broadcasting

Skype-alternativesI have an issue with “meta“ things. I blog, but I’m not engaged with the broader realm of bloggers. Blogging about blogging baffles me. Similarly, although I’ve been involved in the VUC since 2008, I’m not really engaged in the world of podcasters/internet broadcasters. I’m trying to work on this by sharing some of the techniques that I’ve discovered in doing VUC calls.

Last fall I was advising podcaster Mike Phillips with some issues of audio quality with respect to remote participants in podcasts.  He appears to be a frequent contributor to the blog of the IAIB. It was there that I stumbled upon a post recommending Skype Alternatives For Internet Broadcasting.

This post implies that Skype is tremendously popular in this space, and yet there is some desire to seek out functional alternatives. The author, Andrew Zarian, offers the following list of alternatives; Google+ Hangouts, Zoom, Apple’s FaceTime and Cisco’s Jabber. All are certainly worthy of consideration.
