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.

What is next for the Blink SIP client / softphone? What is AG Projects all about? At ITEXPO, host Dan York caught up with AG Projects Founder and CEO Adrian Georgescu and spoke about the Blink SIP client (Adrian doesn’t call it a “softphone”) and about the other work of AG Projects.

What is the new partnership between Skype and Citrix all about? How will it work? Will it be secure? How much will it cost? Will it work on a Mac? At Enterprise Connect 2011 in Orlando, host Dan York interviewed Andrew Sinclair of Skype about Skype’s announcement on March 1, 2011, of the plan to incorporate GoToMeeting technology into Skype.

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 does today’s announcement about “IPv4 address exhaustion” mean? Will the Internet still work? What is all the hype and buzz about? What does this have to do with IPv6? In this episode host Dan York explains what the “IPv4 address exhaustion” news is all about and what it means to you. (He also wrote a blog post explaining IPv4 address exhaustion.)

More articles and info about IPv6 and IPv4 address exhaustion can be found at:

What would the perfect jacket look like for the tech-savvy traveler to conferences and events? How could you easily carry all your technology and content creation gear? Host Dan York caught up with Phil Campbell at a recent event and Phil demonstrated his custom-made “Digital Nomad Jacket” that lets him easily travel with all his equipment.

Note from Dan: The jacket was just way too geeky and clearly had to be recorded! I particularly enjoyed the MiFi-in-the-pocket so that Phil can walk along streaming video directly out of his iPod touch across the cellular networks. And yes, I wouldn’t mind having one of these myself!

In this episode, host Dan York reviews the book “Pragmatic Guide to Git“, written by Travis Swicegood and published in November 2010 by The Pragmatic Programmers. He explains how the book is structured, how he likes the way it works for reference… and one little nit he has about the formatting.

A long-time fan and user of the git distributed version control system, (and on Github as danyork) Dan previously recorded two other ETT episodes about git:

• Emerging Tech Talk #24 – Learning Git, Part 1 – Intro to Version Control Systems
• Emerging Tech Talk #25 – Learning Git, Part 2 – Getting Started with Git

(And yes, he still needs to finish the part 3 that explains Github.)

Voxeo also makes software available through github.com/voxeo and github.com/tropo

What does the brand new Skype 5.0 Beta for Mac look like? How drastically did Skype redesign the user interface (UI)? How well does Group Video work for multi-party video calls?

In this episode host Dan York gets together with Phil Wolff of Skype Journal and Jim Courtney of VoiceOnTheWeb to demonstrate Skype’s new Skype 5.0 Beta for MacOS X, released today and available for free download.

Earlier today, Dan published two blog posts walking through the new user interface and then giving a first look at the group video feature. This ETT video now shows the full effect of how it all works.

What is new with Skype? What will the changes with a new CEO bring? What was the news about Avaya integration all about? What about Facebook integration?

On Oct 5th at ITEXPO West 2010 in L.A., host Dan York interviewed Skype Journal editor Phil Wolff about the latest news from Skype, including the new CEO. (Note: Since the time this was recorded, Skype came out with a new version 5 for Windows that provides some of the Facebook integration we discussed.)

This episode was also an experiment in shooting and producing a video *entirely* on the iPhone 4. Editing was done in iMovie on the iPhone. And yes, the next time I try this I will keep my finger out of the frame.

If you subscribe to Emerging Tech Talk via iTunes, you haven’t seen any shows in a l… o… n… g… time… and then just yesterday you suddenly saw 6 shows appear!

Oops.

It turns out that while I was merrily uploading the shows to YouTube and writing about them here, I was not uploading them to the show’s blip.tv account … and that’s what iTunes pulls from.

Sorry about that.

Why do I use a blip.tv account in addition to YouTube? Two reasons:

1. When I upload a file to Blip.tv, it converts it to the correct format for viewing on an iPod/iPhone; and
2. I can upload episodes in advance and schedule them for release at specific times.

The second reason is particularly useful with some of our major announcements such as our voice biometrics announcement back in February where four videos were released the same morning.

Anyway, I apologize to iTunes users for not updating the feed promptly and I will be making sure I do so in the future.

Thanks for watching!
