CounterPath announces an agreement that would see Zfone integrated as an option into CounterPath's softphone solutions including eyeBeam 1.5 and X-Lite 3.0. This agreement adds a new level of security to CounterPath's VoIP softphone solutions and increases their importance for the enterprise market.

Zfone media encryption for VoIP communications uses a new protocol called ZRTP to achieve risk-free security without reliance on a PKI (Public Key Infrastructure), key certification, trust models, certificate authorities or key management complexity. Zfone performs its key agreements and key management in a pure peer-to-peer manner over the RTP packet stream and interoperates with any standard SIP phone. CounterPath's SIP softphones and softphone SDKs (Software Development Kits), including the eyeBeam 1.5 softphone, provide VoIP, Video over IP, IM and Presence functionalities, and offer flexible VoIP solutions for some of the world's largest service providers and equipment manufacturers including Cisco, Lucent, AT&T, British Telecom and Deutsche Telekom.

The integration of Zfone media encryption into CounterPath's softphones will significantly increase VoIP security levels for CounterPath's customers and end users. Enterprises, service providers and infrastructure manufacturers deploying these softphones will benefit from protection from security threats such as Spam, Denial-of-Service attacks, eavesdropping, spying and wiretapping, while enjoying the same level of security and convenience that they have come to expect from email.
