SAN JOSE, Calif. -- Ingate® Systems ( ), which develops firewall technology and products that enable SIP-based live communication for the enterprise while maintaining control and security at the network edge, and snom, an open systems provider of high quality VoIP business telephones, today announced the world’s first successful completion of an encrypted VoIP call using the approved standard protocol SRTP (Secure Realtime Transfer Protocol).

Ideal for voice traffic, SRTP provides a very high level of security for realtime data with advanced encryption, confidentiality, message authentication, and replay protection. Used with voice data, SRTP provides one of the most secure environments for Internet telephony and VoIP applications available.

To date, only snom and Ingate offer compatible SRTP implementations. The successful completion of interop testing between the two companies offers customers a secure solution for voice traffic: the combination of a snom phone with an Ingate Firewall® ensures a secure, reliable VoIP environment.

snom and Ingate have both incorporated SRTP support to their VoIP products. SRTP was first developed by the Internet Engineering Task Force (IETF) in 2004 as RFC 3711. The SRTP key exchange mechanism used by both vendors is based on the SDP Security Descriptions draft for media streams (sdescriptions). Both companies base their products on the SIP standard, also developed by the IETF. By working to strict IETF specifications, snom and Ingate remain committed to open standards and true interoperability.

"Achieving SRTP interoperability between snom and Ingate Systems marks an important watershed in the evolution of VoIP security," said Michael Knieling, VP Marketing for snom technology, AG. "Single-vendor, proprietary security schemes, developed under wraps, may or may not provide genuine protection. By contrast, standard security strategies receive wide-ranging scrutiny by the developer community, and the process of interoperability testing forces mutual technology disclosure. The result is more robust, provably-secure solutions, and a wider field of options for end users."
