VoIP Security Solution Compatible with Key Avaya IP Telephony Offerings; Sipera IPCS 310 Delivers Real-Time Protection for VoIP Networks

Richardson, TX, May 2, 2006 – Sipera Systems, the leader in pure security for voice over Internet protocol (VoIP), mobile and multimedia communications, today announced that its comprehensive IP communications security product is compliant with key IP telephony solutions from Avaya (NYSE:AV), a leading global provider of business communications applications, systems and services.

The Sipera IPCS 310 protects session-based, real-time IP communication applications, including VoIP, instant messaging, video and multimedia. The Sipera IPCS 310 is compliance-tested by Avaya for compatibility with Avaya Communication Manager IP telephony software and with Avaya SIP Enablement Services used in highly scalable and reliable SIP communications networks.

In addition, Sipera was recently named an Innovator member of the Avaya DeveloperConnection program – an initiative that develops, markets and sells innovative third-party products that interoperate with Avaya technology and extend the value of an enterprise’s investment in its network.

“Avaya’s commitment to open standards like SIP makes the company an ideal partner for Sipera,” said Seshu Madhavapeddy, Sipera president and CEO. “Together with Avaya, we see comprehensive security for VoIP infrastructure as a key requirement for enterprises that want to capitalize on the power of converged networks. Proactively testing for interoperability with Avaya allows us to deliver solutions that make it easier and cost-effective for enterprises to incorporate new technology into their communications infrastructure and utilize it further.”

As a member of Avaya’s DeveloperConnection program, Sipera submits products for compatibility testing by the Avaya Solution Interoperability and Test Lab in Lincroft, N.J.  There, Sipera works with a team of Avaya engineers to develop a comprehensive test plan for each application to verify whether it is Avaya compliant.  Doing so ensures businesses can confidently add best-in-breed capabilities to their network without having to replace their existing infrastructure – speeding deployment of new applications and reducing both network complexity and implementation costs.

“By offering compliance testing to the many innovative companies like Sipera who are members of our DeveloperConnection program, Avaya promotes fully interoperable solutions that help businesses unleash powerful new possibilities,” said Eric Rossman, vice president, developer relations and technical alliances, Avaya.  “They are able to use Intelligent Communications to connect employees and customers to information from wherever they are, over whatever device they have available – getting more out of their multivendor network and delivering new value to their bottom line.”
