Sipera Systems, the leader in pure security for VoIP, mobile and multimedia communications, has won the 2006 Best of Interop Award in the VoIP and Collaboration category for its Sipera IPCS 310 product. The Best of Interop Awards are sponsored and judged by CMP Media's Network Computing.

The Sipera IPCS 310 is the most comprehensive pure security solution for protecting real-time IP communications applications such as VoIP, instant messaging (IM), video and multimedia. The Sipera IPCS 310 is deployed within the network to protect both the infrastructure and end-users from a number of malicious, application-specific attacks and service abuse.

"Winning this award is both a testament to the abilities of the Sipera team and to the vision of its founder and CTO Krishna Kurapati, who started Sipera over two years ago with the mission to create a comprehensive security solution for IP communications applications," said Seshu Madhavapeddy, Sipera president and CEO. "This award is a validation of that vision and the market leadership of the Sipera product."

"Best of Interop Awards showcase and recognize the innovators and leaders in their product category," said Ron Anderson, lead judge of the 2006 Best of Interop Awards and lab director for Network Computing. "Congratulations to Sipera as well as all of the category winners that demonstrated superior technology and innovation making it especially difficult for our IT Analysts to choose just one winner in each category."

Sipera IPCS products can be deployed in any existing VoIP infrastructure with no need for on-site interoperability testing, due to Sipera's close development and integration work with leading VoIP infrastructure manufacturers. This week Sipera announced the completion of successful interoperability with both Avaya and Nortel.
