Speaking at SIPNOC Next Week About IPv6 and DNSSEC With VoIP

SIPNOC 2013 logoInterested in how voice-over-IP (VoIP) can work with IPv6? Want to know how DNSSEC can add a layer of security to VoIP?  Next week I’ll be speaking on these precise topics at the SIP Network Operators Conference (SIPNOC) sponsored by the SIP Forum and happening in Herndon, Virginia.

SIPNOC is an excellent conference that I’ve very much enjoyed over the past few years that brings together many of the key players involved with moving our telecommunications infrastructure from its PSTN roots into the world of IP communications. Its target is operators and so you have a good number of people there who are providing VoIP services to customers – typically using the SIP protocol.  The schedule is always an interesting mix of operational best practices, security concerns, new technologies, policy and other topics.  This year it’s good to see WebRTC being on the agenda in several places, as that will have an effect on the overall VoIP infrastructure.  (FYI, there is still time to register to attend the SIPNOC event.)

As shown on the SIPNOC schedule, I’ll be participating in these sessions:


IPv6 And SIP – Myth or Reality?
Wednesday, April 24, 10:45-11:45am

In this session we’ll be exploring what is really going on with VoIP and IPv6 and seek to answer questions such as:

  • What’s going on with SIP over IPv6?
  • What are the main challenges to using SIP with IPv6?
  • What do we know about the status of current equipment working with IPv6?
  • What are the SIP Forum and others in the industry doing to help advance the state of the art?
  • Where do we see SIP and IPv6 going?

I’m very much looking forward to the session and have several panelists joining me in a discussion-style panel that should be quite educational and interesting.


Who are You Really Calling? How DNSSEC Can Help
Thursday, April 25, 9:30-10:00am

My goal with this session is to explain what DNSSEC is all about and to look at how it can potentially help to secure a few aspects of VoIP communication.  As I wrote in the abstract:

When Alice calls Bob, how does she know that she is really communicating with Bob’s SIP server? Sure, her software grabs a SRV record for Bob’s server from DNS, but how does Alice’s systems know whether that is the *correct* DNS record for Bob’s server? What if an attacker were able to inject DNS records that redirect Alice’s call to another system? What if there were a way that the SIP endpoints could be certain about the address of the other system they want to call?

I’ll also be talking about the Jitsi softphone that now supports DNSSEC as I wrote about in the past and more recently interviewed Emil Ivov, the Jitsi project lead.  I hope to get some people thinking about the possibility of using DNSSEC and looking into how it can work more with their VoIP infrastructure.


Beyond those sessions, I’ll also be engaging the “VoIP security” side of my background and moderating two sessions on Monday, April 23:

  • 5:15-6:15pm – Panel Discussion:  Anatomy of  a VoIP DMZ
  • 7:30-8:30pm – VoIP Security Birds-of-a-Feather (BOF)

The BOF, in particular, should be interesting as last year it was a very frank and open conversation between operators about the security issues they were facing.  Much good information – and solutions – were exchanged.

I’m very much looking forward to this event and if you are going to be at SIPNOC please do say hello.

At the current time the event is not being livestreamed, but I’m planning to record at least my sessions and make the video available through the Deploy360 YouTube channel.

Slides: SIP and IPv6 – Can They Get Along?

Last week at the SIPNOC 2012 event in Virginia, I gave a presentation about how the Session Initiation Protocol (SIP) can work with IPv6 and what some of the issues are around deployment.  I emphasized the fact that SIP works over IPv6 and then took a step back to talk about the basics of IPv6 before diving into more SIP- and VoIP-specific issues.  There was some great discussion and I learned later that a number of people took photos of my slide about SIP and NAT. 🙂

To that end, my slides about SIP and IPv6 are now available online for your viewing and/or downloading.  I did record the event on video – and at some point here I’m aiming to publish that to our YouTube account.  Meanwhile, enjoy the slides…

Speaking about IPv6 and SIP (VoIP) Next Week at SIPNOC in Virginia

SIPNOC logoHow well does the Session Initiation Protocol (SIP) work with IPv6? How do current VoIP software and systems currently handle IPv6?  What does the industry need to do for SIP to thrive in an IPv6 landscape?

I’ll be exploring all those questions and much more at the “SIP Network Operators Conference (SIPNOC)” next week in Herndon, Virginia, USA.  SIPNOC is a great event sponsored by the SIP Forum that brings together network operators and many other companies all involved in actually deploying and using SIP for voice over IP. I really enjoy the event as the participants are really on the leading edge of IP communications. This year, too, the CTO of the US Federal Communications Commission (FCC), Henning Schulzrinne, will be giving what should be an interesting keynote. (And it’s not too late – you still can register to attend SIPNOC!)

As noted on the agenda, I’ll be participating in three sessions during the two-day event:

Tuesday, June 26

10:30am-11:15am: Panel Discussion: SIP Adoption and Network Security.

Along with Eric Burger of Georgetown University (and also an Internet Society Board of Trustee) and Randy Layman of Vocalocity, I’ll be discussing VoIP security issues, a topic I’ve long been involved with.

11:45am-12:15pm: SIP and IPv6 – Can They Get Along?

My main session for the event. The abstract is as follows:

With World IPv6 Launch happening June 6, 2012, production IPv6 network connectivity will be available to many more businesses and individuals. Major web sites and content providers will all enable IPv6 access to their content. Consumer electronics manufacturers are committing to providing IPv6-enabled devices.

What does this mean for SIP-based real-time communications? How well does SIP work with IPv6 today? What are the challenges to deployment and what steps can be taken to overcome those challenges? What should operators and vendors consider with regard to SIP and IPv6? What software, devices and tools are available to assist? And what case studies and other information is available?

In this session Dan York will discuss all of these points and provide concrete suggestions for moving forward with SIP and IPv6. The session will also provide time for sharing of experiences and insight of the attendees. Please bring your questions, ideas and be prepared for a lively session looking at how SIP and real-time communications can work in the new IPv6-based Internet.

We’ll post slides and hopefully video after the event is over.

Wednesday, June 27

12:45pm-1:30pm: BoF: SIP and IPv6

This will be an open forum for discussion of SIP and IPv6-related issues.  At last year’s SIPNOC event the session was very well attended and there were great discussions about issues people were having, examples of where IPv6 worked well and questions people had about tools and services.  I’m hoping we get that level of participation again and that it can be a useful learning experience for all involved.

If any of you will be attending SIPNOC I look forward to meeting up with you there.
