IPv6 and IP Communications (including VoIP, UC, RTC, SIP)

This page will serve as a repository of information of information related to IPv6 and communications protocols based on IP, including voice-over-IP (VoIP), unified communications (UC). real-time communications (RTC) and the use of the Session Initiation Protocol (SIP).

(NOTE: Need to include reference here to how WebRTC is designed to work with IPv6.)


Presentation Slides


There is a good amount of discussion about IPv6 happening in various IPv6 communities around the Internet. More specific discussion about IPv6 and IP communications is happening here:


We are aware of the following softphones that support IPv6:

Communications Equipment

Beyond softphones, we are aware of the following equipment that supports IPv6.

(NOTE: Links need to be added, ideally to IPv6-specific pages. Also, it is worth considering whether this list should be moved to a separate page.)

  • Avaya (unclear on exact models)
  • Mitel 53xx Series
  • Mocet
  • Siemens OpenStage
  • Snom
  • Yealink SIP-T2x

Additional resources will be added to this page as we become aware of them.

Know of additional resources related to IPv6 and IP communications that we should list?  Please let us know!

Video – DNSSEC Deployment In The .GOV TLD (LISA 2012)

How did the deployment of DNSSEC go within the .GOV top-level domain? What kind of errors were found in the deployment?  What lessons were learned?  If they could start it all again, what would they do differently?

These were all questions discussed by Scott Rose of the US NIST in a talk last December at LISA 12 (where we had ION San Diego) titled “DNSSEC Deployment In The .GOV TLD“.   As we can know from NIST’s own statistics it was a long road to get DNSSEC deployed – but the latest stats now show around 81% of all .GOV domains being signed.

Scott’s talk is quite good and offers some good lessons for anyone interested in rolling out DNSSEC in a very large organization or community.  From the LISA 12 presentation page, you can either watch the video or listen to the audio.
