Data Connection Limited, the world's leading independent provider of communications protocol software, announced its participation in SIPit 19, the nineteenth SIP interoperability test (SIPit) event organized by the SIP Forum (www.sipforum.org).

SIPit is a week-long event, held twice a year, to improve the quality of the SIP specification and forge global interoperability among SIP implementations. Data Connection was one of over seventy vendors who participated in the event, which was hosted by the University of New Hampshire Interoperability Laboratory.

At the event Data Connection deployed DC-SIP, its carrier grade protocol stack utilized by softswitches, gateways, servers, phones, access devices, and IMS applications throughout the world. DC-SIP, which includes IPv6 functionality, successfully interoperated with a number of SIP solutions in peer-to-peer and multiparty test environments.

“The SIPit events are a great opportunity to ensure industry compatibility and advance SIP technology in general. For example, we were able to confirm multi-vendor interoperability with our IPv6 implementation in a matter of hours,” said Jonathan Cumming, Data Connection’s Director of VoIP Product Management for Networking Protocols. “This is why Data Connection has been a frequent participant in the past SIPit events and plans to continue its involvement.”
