Lifesize® Partners with Paradial to Develop Firewall/NAT Traversal Solution

Paradial's RealTunnel® Technology to Provide Lifesize Customers Secure and Reliable High Definition Video Connections

Austin, Texas — Apr 28, 2006

Lifesize, the high definition video communications company, today announced that it is partnering with Paradial to develop a firewall/NAT (Network Address Translation) traversal solution for video communications. Leveraging Paradial's RealTunnel technology, Lifesize will enable customers to make video calls within and across enterprises by securely traversing firewalls.

Concerns over network security and integrity have hindered the ability for some organizations to utilize and support video communications between IP networks. Conducting video calls by passing through a network firewall meant opening and closing multiple communication ports, leaving networks vulnerable to possible attacks.

Paradial's RealTunnel is a comprehensive firewall/NAT traversal technology and works with virtually any SIP clients and any firewall/NAT device - including strict corporate firewalls - without compromising network security levels or requiring network reconfigurations. Lifesize customers will be able to conduct global IP video communications that do not place their networks, data or businesses at risk.

"We conducted a thorough evaluation process for determining which firewall/NAT traversal solution to offer our customers," said Craig Malloy, CEO of Lifesize. "By working with Paradial's unique technology, Lifesize can rapidly bring to market a world class firewall/NAT traversal solution that will increase the reach of video communications for our customers."

"We are delighted to partner with an industry innovator like Lifesize," said Kevin Kliland, CEO of Paradial. "By working closely with Lifesize, we will be able to jointly extend our presence in, and subsequently grow, the global video communications market."
