What is the Call Control UUI Service for SIP (a.k.a. “CUSS”) Working Group within the IETF all about? What is “user-to-user information”(UUI)? Why should you care about it? What would standardizing UUI do for SIP systems?

At the SIPNOC event in April 2011, Voxeo’s Dan York sat down with Alan Johnston, lead author of one of the primary drafts in the CUSS working group, to understand what CUSS is all about, what problems it is aiming to solve, the timeframe it is working on and much more.

More info about CUSS can be found here:

• CUSS Working Group charter
• Internet-Drafts related to CUSS
• Mailing list for those interested in monitoring or participating in CUSS

The CUSS working group was formed in September 2010 and participation in the group is open to anyone.

Wouldn’t it be great if you could connect via video over IP to someone at another company? Or to be able to use a wideband audio codec to have a richer sound to your calls? Sure, you can do this today with Skype… but not with your SIP-based or other IP-based IP-PBX or communications server. We don’t have any easy way of connecting with someone directly across the IP network… instead we wind up placing calls over the standard PSTN – even if both recipients could communicate over IP.

There are several different ideas out there about how to solve this, but one of the more interesting to me is the “VIPR” approach suggested by Cisco Systems and now involving a few other companies. While at ITEXPO last week in Miami, I (Dan York) had a chance to interview Cisco’s Cullen Jennings who has been very involved with the VIPR effort.

Is VIPR, a.k.a.”Verification Involving PSTN Reachability”, as journalist Doug Mohney said, “the big hack to get around the lack of direct SIP peering between Tier 1 service providers“? How does it work? How can you learn more? (Hint: start with this Internet draft: draft-rosenberg-dispatch-vipr-overview) How can you get involved?

Watch to learn more…

What is the SIPit test event all about? How does it make communications systems better? What do participants do at the event? How can companies get involved? To answer all those questions and more, host Dan York interviewed SIPit coordinator Robert Sparks at the SIPit 25 event held in September 2009 at the University of New Hampshire InterOperability Lab (IOL) in Durham, NH, USA.

More information about SIPit can be found at http://www.sipit.net/
Many thanks to Robert for agreeing to the interview after a long day of testing. Robert has also posted a summary of the SIPit25 event at:

What is Peer-to-Peer SIP (P2PSIP) all about? Who would use it? Is it really just an attempt to make an open standards Skype? What standards are being created?

All those questions and more were discussed when host Dan York caught up with David Bryan, co-chair of the IETF P2PSIP Working Group, out at the IETF 73 meeting in November 2008 in Minneapolis, MN. More information about P2PSIP can be found at http://www.p2psip.org/

Why did Google sponsor the 73rd meeting of the Internet Engineering Task Force (IETF) this month (Nov 2008) in Minneapolis, MN? What is Google’s interest in IETF and standards anyway? And what about open source? In this show, host Dan York sits down with Chris DiBona, Google‘s Open Source Programs Manager, to discuss these and other questions.

This interview with Chris DiBona was recorded at the IETF 73 meeting in Minneapolis, Minnesota, on November 18, 2008. As you can probably tell, my camera was placed on a piece of furniture about ten feet away from where Chris and I were sitting. The audio was simply recorded with the camera’s microphone and then I did some post-production to try to bring the volume up a bit. And yes, that was the very high-end suite in the hotel that Google was given as a result of sponsoring the event.

Dan York is still up in Minneapolis, Minnesota, at the 73rd meeting of the Internet Engineering Task Force (IETF) and in this show he talks about the conference so far and some of the discussions within the Realtime Applications and Infrastructure (RAI) area around how to work more effectively on the specifications around SIP. The “rai-discuss” mailing list Dan mentions can be found at: https://www.ietf.org/mailman/listinfo/rai-discuss It is a open, public mailing list that anyone who is interested can join and participate. The Internet-Draft Dan mentions about is draft-matuszewski-p2psip-security-requirements. The IETF 73 meeting continues through tomorrow (Friday, November 21, 2008).
