The IETF MARTINI WG has been chartered to standardize an important aspect of SIP trunking: multiple AOR registration. This is not one of those "we'll deliver a standard when we're good and ready" working groups. This WG is aiming to deliver a single standard solution that can displace the myriad of adhoc "implicit registration" approaches that exist today. The goal is to change SIP trunking forever, or die trying. Not 5 years from now, not 2 years from now, but NOW. MARTINI will hold its third virtual Interim (yup, three 2.5+ hour interims in a period of less than 6 weeks) on February 9, 2010. If you are a Voice over IP service provider, and you care about the future of SIP trunking, then you need to attend MARTINI Virtual Interim III, or lose your whining rights, forever. The strawman agenda and the conference parameter details are available here: http://www.ietf.org/mail-archive/web/martini/current/msg00462.html Presentations and minutes from the previous virtual interims are available here: http://www.drizzle.com/~aboba/MARTINI/ The IETF MARTINI WG: not another half-baked standards working group that nobody cares about.
