Video Interview: Emil Ivov about how the Jitsi softphone works with IPv6 and DNSSEC
Continue Reading: Video Interview: Emil Ivov about how the Jitsi softphone works with IPv6 and DNSSECHow does the Jitsi softphone work with IPv6? And what role could DNSSEC play with VoIP? At IETF86 earlier this month, I sat down with Emil Ivov, project leader of the Jitsi Project to talk about a wide range of topics including how Jitsi got started and why it does so much with IPv6 (interesting reason!), what they are looking to do with Jitsi now, the role of DNSSEC and why they added that support to Jitsi… and much, much more… I quite enjoyed talking to Emil and the Jitsi project is certainly one that I will continue to watch – and use!If you found this post interesting or useful, please consider either:

VUC Today: The Jitsi VoIP Softphone – Join The Call To Learn More!
Continue Reading: VUC Today: The Jitsi VoIP Softphone – Join The Call To Learn More!What is new with the Jitsi softphone these days? What new capabilities does it have as it continues to expand its support of SIP, XMPP and other protocols?
I’ve long been a fan and user of Jitsi, in part because it supports IPv6 and is the only VoIP softphone I know of right now that supports DNSSEC, something I’m continuing to experiment with, so I’m looking forward to today’s “VoIP Users Conference (VUC) call at 12 noon US Eastern – about 2.5 hours from now.
You can watch it live via a Google+ Hangout On Air, or call in (potentially using Jitsi!) via:
- sip:200901@login.zipdx.com
- +1 (646) 475-2098
- Skype:vuc.me
There’s also an IRC backchannel where links are shared, questions are answered and other comments occur.
And for those of you using Google+, there is a Google+ Event you can join.
It should be a good show! (And yes, you can watch it / listen to it later…)

Continue Reading: “Catching Up With Dan York” On The VUC Call Tomorrow At Noon US Eastern – Please Join Us!Want to learn more about what I’m doing these days? Both with my work with the Internet Society Deploy360 Programme as well as other various projects? And what any of that has to do with VoIP and real-time communications these days?If so, join us tomorrow, Friday, March 1, at 12 noon US Eastern on the “VoIP Users Conference (VUC)”. You can join a Google+ Hangout, or call in via:
- sip:200901@login.zipdx.com

There’s also an IRC backchannel where links are shared, questions are answered and other comments occur.
As long time readers know, I’ve been a huge fan of – and participant in, when I’ve been able to – the VUC calls and community that Randy Resnick has been spearheading since March 2007.
I don’t remember when precisely I first started joining in… maybe sometime in 2007 or 2008. In those early days (and still today) it was a great place to discuss open source telephony solutions like Asterisk, Freeswitch and others. The VUC became a place where many of us gathered weekly to learn about the latest technologies from various projects or vendors… and just to chat about various topics relating to VoIP, Unified Communications, SIP…

WebRTC Passes Huge Milestone In Rewiring The Web – Video Calls Between Chrome and Firefox
Continue Reading: WebRTC Passes Huge Milestone In Rewiring The Web – Video Calls Between Chrome and FirefoxThis week the WebRTC/RTCWEB initiative passed a HUGE milestone in adding a real-time communications layer to the Web with achieving interoperability between Google Chrome and Mozilla Firefox. Google and Mozilla celebrated with a pair of blog posts:They also published the video I’ve embedded below. On the surface, the video doesn’t appear terribly exciting: two guys having a basic conversation over video. But consider this:
- The video conversation was initiated from within web browsers.
- There were NO plugins used… no Flash, Java or anything else.
- The entire conversation was securely encrypted.
- The call used “wideband audio” (also called “HD audio”) to provide a much richer experience that far exceeds any kind of conversation you can have on traditional telecom and mobile networks.
- The call did not have to involve any external telecom networks or services and could have been initiated directly from one browser to the other. (I don’t know exactly how they set up this call.)
And perhaps most importantly:
Any web developer can now create this kind of real-time communication using a few lines of JavaScript and other web programming languages.
As I’m said before, WebRTC will…

Oracle Buys Acme Packet For $2 Billion To Gain SIP Session Border Controllers (SBCs) And More
Continue Reading: Oracle Buys Acme Packet For $2 Billion To Gain SIP Session Border Controllers (SBCs) And MoreFascinating news today out of Oracle that they have purchased Acme Packet in a transaction estimated to be around $2 billion US. For those of you not really tracking the VoIP security space, Acme Packet is probably the world’s largest vendor of “session border controllers (SBCs)“, devices that are used to securely and reliable interconnect VoIP networks. SBCs also provide a very important role in helping with interoperability of Session Initiation Protocol (SIP) signaling between the SIP products and networks of different vendors.As Andy Abramson writes, the fascinating aspect of this acquisition is this:
This is an interesting grab by one of the tech world’s true giants because it sqaurly puts Oracle into a game where they begin to compete with the giants of telecom, many of whom run Oracle software to drive things including SBC’s, media gateways and firewall technology that’s sold.
This acquisition does put Oracle VERY firmly into the telecom sector at a carrier / large enterprise level, as Acme Packet’s products are widely used within that tier of companies. As the news release notes:
“The company’s solutions are deployed by more than 1,900 service providers and enterprises globally, including 89 of world’s top 100…

Next SIPit Test Event Feb 18-22 – Deadline of Feb 4 For Registration
Continue Reading: Next SIPit Test Event Feb 18-22 – Deadline of Feb 4 For RegistrationAre you a vendor of SIP-based products and services? Do you have software or hardware (or cloud-based products) that use SIP? If so, are you planning to attend the next SIPit test event planned for February 18-22, 2013, in Raleigh, North Carolina?
The SIPit events are an outstanding place to test your SIP implementations. Where else will you have so many other vendors also testing their equipment? It’s a great place to go, test… and iterate your code even while you are there so that you can test again.
The registration deadline is Feb 4, 2013 for SIPit 30, so you need to act soon if you want to attend.
Olle Johansson posted a great set of slides about why you should go to SIPit: Participate in SIPit from Olle E Johansson
And reaching back to 2009, here’s a video interview I did with Robert Sparks about the SIPit test events:
If you are a vendor of SIP products or services, I would strongly encourage you to consider attending the next SIPit. It’s a great way to make sure your SIP works as best as it can.

Continue Reading: Last Day To Submit Speaking Proposals for SIPNOC2013Got a great idea for a talk to give to an excellent gathering of SIP/VoIP network operators? Have a new way of handling security? Have a case study you’d like to present for how you solved an operational issue?The SIP Network Operators Conference (SIPNOC) is an outstanding event happening in Herndon, Virginia, USA, from April 22-25. It brings together network operators working with SIP / VoIP networks for several days of talks, networking (of the human kind) and education. I’ve gone the past two years, speaking about IPv6, and they are truly excellent conferences. Not too big, not too small… and with an extremely high quality of people both attending and speaking.

Facebook Rolls Out Free Voice Calls In The US On iOS – A Quick Walkthrough And A Big, Huge Caveat
Continue Reading: Facebook Rolls Out Free Voice Calls In The US On iOS – A Quick Walkthrough And A Big, Huge CaveatFacebook today rolled out it’s free voice calling in the US via its Messenger app for iOS (iPhone/iPad). The Verge was the first I saw with the news and a great number of sites are now following.Voice calling through Facebook has the potential to be hugely disruptive… rather than calling on your phone over your regular phone connection – or even rather than using Skype, you can just call from directly within Facebook. This is the kind of “Over-The-Top (OTT)” app that gives telco operators a fit… goodbye, telco voice minutes!
Plus, it’s using some HD voice codec so the sound quality is outstanding.
And since the folks at Facebook want you to live your life inside of their very pretty walls, this just provides yet one more reason for you to stay within those walls.
BUT… there’s a big huge caveat that I’ll get to in a moment.
A Quick Walkthrough
First, though, let’s look at how it works. When you go into the Messenger app and open a chat with a friend (in this case, Jim Courtney), all you have to do is click the “i” button in the upper right:
After you do that…
