SIP Forum has released the test results from the latest SIPit event SIPit 28, the SIP interoperability event, was hosted by Digium on April 11–15, 2011 and held at the Jackson Center in Huntsville, Alabama's Research Park. 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. There were 19 companies from 10 countries who participated in the SIPit 28 to test and confirm SIP interoperability this spring. High definition IP video was a key focus at the event and IPv6 support in the industry was also on the rise, the forum noted.

"SIPit28 was one of the smoothest events to date featuring a lot of positive energy and hard work from all involved, We received great feedback from participating companies who were able to glean a good deal of valuable data which provided them a very high return.", said Robert Sparks, chair of the SIP Forum's Test Event Working Group and organizer of SIPit 28.said Robert Sparks, chair of the SIP Forum's Test Event Working Group and organizer of SIPit 28.

NORTH ANDOVER, MA (June 27, 2011) - The SIP Forum has announced the results of its latest SIP Interoperability Testing event, SIPit 28, the world's premier interoperability testing event for the Session Initiation Protocol (SIP) for application developers, service providers, and IP communications equipment manufacturers, held earlier this spring at Jackson Center in Huntsville, Alabama's Research Park. Hosted by Digium, 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 28 provided 19 attending companies with valuable "real-world" deployment data gathered from the 40 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, which took place April 11-15, participants showed a growing interest in deployment of high definition (HD) video services across global IP networks. Participants executed a number of different telepresence scenarios with intricate SIP signaling, testing for quality of service (QoS), network resiliency and interoperability involving new types of rich media endpoints with IP application servers, SIP proxy servers and session border controllers.

"Rolling out IP video in both enterprise and service provider networks and making it work is a key objective for many operators, equipment makers and application developers in today's telecom world and is something attending companies really focused on at this year's SIPit" said Robert Sparks, chair of the SIP Forum's Test Event Working Group and organizer of SIPit 28.

"We were able to successfully execute a number of testing scenarios that examined different network topologies under a variety of simulated conditions. Participants were able to verify correct behavior of advanced applications in an environment that is very difficult to duplicate without so many different implementations in the same room at the same time."

In addition, IPv6 was also a hot topic in preparation for the industry-wide rollout of this next generation Internet protocol, with many participants uncovering new, positive information surrounding interoperability of IPv6 equipment and services, particularly when implementations use a combination of IPv6 and IPv4 for media and signaling. Across the testing, 68 percent of the implementations at the event supported IPv6 which represented a significant increase from SIPit 27 in 2010 which saw 53 percent of attendees achieve IPv6 support.

A full summary report of SIPit 28 results is available at the SIP Forum website or by clicking here (https://www.sipit.net/SIPit28_summary).

"The SIPit events continue to be critically important and popular 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, real-world testing environment," said Marc Robins, SIP Forum President and Managing Director. "Every time we have a SIPit event, we receive scores of positive feedback about how valuable the testing was to the development of products and services, as well as how useful it is to standards bodies such as the IETF for gaining insight into the growth of SIP and the specific SIP implementations."

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 28 events around the globe. In the coming months, the SIP Forum will release details about its next event - SIPit 29 - which will be hosted by ETSI and take place this fall in France.

"SIPit28 was one of the smoothest events to date featuring a lot of positive energy and hard work from all involved," continued Sparks. "We received great feedback from participating companies who were able to glean a good deal of valuable data which provided them a very high return."
