SIP Forum Releases Results from SIPit 26 in Kista, Sweden

Week-long interoperability testing event drew attendees from 28 companies in 15 countries; SIP security and IPv6 interworking highlight the 42 distinct implementations tested at the event

NORTH ANDOVER, MA (July 7, 2010) – The SIP Forum has announced the results of its latest SIP Interoperability Testing event, SIPit 26, the world’s premier interoperability testing event for Session Initiation Protocol (SIP) for SIP application developers, service providers, and IP communications equipment manufacturers, held May 17-21, 2010 in Kista, Sweden. The five-day testing event demonstrated continued growth and evolution in SIP-based technology as SIP-based consumer and enterprise applications become more broadly deployed across fixed and mobile IP network topologies.

The event, which was hosted by Edvina and TANDBERG and sponsored by Intertex, Ingate, and .se, with the IPv6 Forum serving as an association sponsor, provided 28 attending companies with valuable “real-world” deployment data gathered from the 42 SIP implementations conducted during the week as participants tested SIP interworking in a variety of simulated, live IP network conditions and settings. Of particular note was an increase over past events in the number of Secure Real-time Transport Protocol (SRTP) and TLS implementations for secure SIP interworking, and the continued and steady growth of IPv6 implementations.

“As SIP communications become more widely prevalent, securing SIP at both the application and media layers through SRTP and TLS is critical,” said Robert Sparks, chair of the SIP Forum’s Test Event Working Group and organizer of SIPit 26. “Other interesting developments were the growth of IPv6 and a large number of participants testing network edge-specific scenarios with ICE and TURN implementations.”

“SIPit events bring together a diverse array of stakeholders from the global telecom community – SIP application developers, IP communications equipment manufacturers, and service providers – and provides them with an opportunity to glean valuable technical data about new SIP specifications and implementations important to their business, in a neutral setting,” said Marc Robins, SIP Forum President and Managing Director. “The event and the resulting data also give standards bodies such as the IETF a good progress report on the growth of SIP and the specific SIP implementations that are becoming more widely adopted in the service provider, enterprise, and consumer markets.”

SIPit is organized by the SIP Forum’s Test Event Working Group (TEWG) and serves as a “plugfest” for participating companies to perform SIP interoperability testing with other participants in a live network environment. Conducted twice a year, with events rotating in the United States, Europe, and Asia, the SIP Forum has hosted 26 plugfest events around the globe. In the coming months, the SIP Forum will release details about its next event – SIPit 27 – which will take place this fall. For information about past SIPits, please visit

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 interoperability and testing events, special interoperability workshops, educational seminars, and general promotion of SIP in the industry. One of the Forum’s notable technical activities is the development of the SIPconnect Technical Recommendation – a standards-based recommendation that provides detailed guidelines for direct IP peering and interoperability between IP PBXs and VoIP service provider networks. The SIPconnect Compliant Certification Program is an associated program through which eligible companies can gain SIPconnect validation and the right to license the use of the SIP Forum’s ‘SIPconnect Compliant’ certification mark – the official brand of the leading standard for SIP Trunking products and services. Other important Forum initiatives include work in Fax-over-IP interoperability, User Agent Configuration, and the opportunities for SIP in Smart Grid deployments. For more information, please visit:
