Hosted by the European Telecommunications Standards Institute (ETSI); 16 companies from 9 countries participated in the latest SIPit interoperability testing event; Multi-party testing emphasized NAT/Firewall traversal, TLS, SRTP, and IPv6.
NORTH ANDOVER, MA (October 22, 2014) – The SIP Forum has announced the results of its latest SIP Interoperability Testing event, SIPit 31, the world’s premier interoperability testing event for the Session Initiation Protocol (SIP) for application developers, service providers, and IP communications equipment manufacturers, held in Nice, France, September 30-October 3, 2014. Hosted by ETSI, the five-day testing event once again demonstrated the critical role that Session Initiation Protocol (SIP) plays in today’s telecommunications industry while also highlighting the growth, evolution and adoption of SIP services in fixed and mobile IP networks worldwide.
SIPit 31 provided 16 attending companies with invaluable “real-world” deployment data gathered from the 21 distinct SIP implementations conducted during the week as participants tested SIP interworking in a variety of simulated, live IP network conditions and settings. Testing exercised the full range of defined transport protocols for SIP, from UDP to TLS over SCTP.
As part of the week-long testing event, 47 participants showed a growing interest in deployment of IPv6-compliant solutions. Other multiparty tests involved a focused test on SRTP, with a mix of sdes and dtls-srtp capable devices; TLS testing using the SIPit self tests as well as server-to-server connections; and ICE tests that were done with a lab network with multiple NATs, v6-only networks, v6 native, with natted v4, and two networks with the same RFC1918 addresses. Testing included advanced network configurations (multiple available Ipv6 prefixes), and advanced DNS configuration, resulting in very large Session Description Protocol (SDP) bodies.
“The demand for secure, robust real-time communication is driving rapid innovation in protocols and products.” said Robert Sparks, chair of the SIP Forum’s Test Event Working Group and organizer of SIPit31. “It is critical that new applications work together using standard building blocks. The SIPit testbed continues to provide attendees with a much more effective test environment than can be achieved with individual peer-wise testing.”
“The SIPit events continue to be critically important events for the IP communications industry because they give participants an opportunity to vigorously test implementations of their own IP communications product or service with other members of the telecom community in a non-commercial, highly cooperative, real-world testing environment,” said Marc Robins, SIP Forum President and Managing Director.
According to Jens Flensborg, Director of R&D at Spectralink Europe, “We make a product which relies on SIP to give us access to the Unified Communications market, thus increased SIP interoperability directly increases our addressable market. At SIPit we get a chance to expose our SIP implementation to other vendors, and get exposed to the SIP implementation from other vendors. We bring, and are faced by, new techniques and additions to the SIP standards before they hit the market, giving us the ability to identify and eliminate bugs before it affects customers, as well as accelerate our time-to-market in bringing new features to our customers.”
Another attendee, Matthew Jordan, Asterisk Project Lead at Digium, said, “The benefits from participating in SIPit testing have been outstanding for Digium and Asterisk 13. The sheer breadth of scenarios and different communication stacks utilized at SIPit events guarantees that everyone finds aspects of their communication stacks to improve upon. SIP – as well as companion protocols such as SDP and RTP – continue to evolve and change. Having a dedicated venue where all members of the communications industry can work together to improve the specifications and their products benefits everyone – including the users of Asterisk.”

SIPit is organized by the SIP Forum’s Test Event Working Group (TEWG). Conducted once a year, the SIP Forum has hosted 31 SIPit events around the globe. In the coming months, the SIP Forum will release details about its next SIPit event – SIPit 32. For information about past SIPits, please visit www.sipit.net.
About the SIP Forum
The SIP Forum is an IP communications industry association that engages in numerous activities that promote and advance SIP-based technology, such as the development of industry recommendations, the SIPit, SIPconnect-IT and RTCWeb-it interoperability testing events, special workshops, educational seminars, and general promotion of SIP in the industry. The SIP Forum is also the producer of the annual SIPNOC conferences (for SIP Network Operators Conference), focused on the technical requirements of the service provider community. One of the Forum’s notable technical activities is the development of the SIPconnect Technical Recommendation – a standards-based SIP trunking recommendation that provides detailed guidelines for direct IP peering and interoperability between IP PBXs and SIP-based service provider networks. Other important Forum initiatives include work in Fax-over-IP interoperability, User Agent Configuration, Video Relay Service interoperability, security, NNI, and SIP and IPv6.
