SIPit is the main interoperability event for all things SIP. It’s organized by the SIP Forum and creates good feedback to the IETF. Asterisk has been participating in SIPit during many years and in many variants  - videocaps, Marc Blanchet’s IPv6 branch and the standard Digium releases. All these tests has lead to a large amount of improvements for Asterisk and have helped us to build a network with other developers in the business, a network which helps when we have bugs that involve interoperability with these devices or servers. SIPit has proven important for the success of Asterisk, and thus it is also important for  everyone in the Asterisk community. 

Now, when we are working on the next  long-term release (1.8) we really need to test again and make sure that we interoperate properly. New stuff, like Terry’s SRTP branch, my RTCP work and the call completion and caller ID update work needs serious testing. We need feedback to be able to fix the issues with the TCP and TLS support.

Interoperability drives the TCP/IP business

What drives the TCP/IP business is simply stated in one word – “INTEROPERABILITY”. Without open network standards, the VoIP business would not be as large as it is today. Without working and tested standards, it would not work at all. After all, the IETF’s mantra is “rough consensus and running code”Asterisk, as an Open Source platform is in the middle of this business. We simply have to interoperate with all kinds of phones, servers and services out there. It’s the basis of our success, since we offer no clients at all.

SIPit 26 – in Sweden, hosted by Edvina

SIPit is organized by the SIP Forum and every SIPit – two per year – is hosted by a company. During good times, the large vendors has taken care of this. In the current climate, it’s hard to get the needed resources – time and money – from these vendors. SIPit 25, yes the 25th in a successful series, was organized by the Interoperability Labs at University of New Hampshire in September 2009. Digium helped out by providing the PBX infrastructure for the event. The next one, SIPit 26, will be in Stockholm, Sweden - hosted by myself with support from Tandberg and sponsored by a set of companies.

SIP interoperability is a requirement – for you, your customers, your business

So why I am doing this? The business needs it, Asterisk needs it and I need it. Without SIPit, you will notget good products that work together. Without SIPit, tests will be limited to certification of a very limited setof functions by different vendors. I believe that this will lead to unhealthy market domination in theimplementations, something that does not benefit the customers.And besides, after creating Astricon in the US and a series of other conferences in Sweden, I haveexperience of organizing events. I am crazy enough to step forward and take the risk, since I reallystrongly believe that we all benefit from this.Now I need your support too.

Additions to your already filled-up TODO-list:

  • If you develop SIP software, make sure you register and attend.
  • If you buy SIP devices or software, ask the vendors if they attend SIPit and encourage them to participate
  • If you have collegues that work with SIP development, please forward this mail to them!
