Ingate Systems Earns 3Com Enterprise Voice Over Internet Protocol Certification

Ingate to Showcase Firewalls and SIParators at 3Com's N+I Booth

NETWORLD+INTEROP, LAS VEGAS, May 3, 2005- Ingate® Systems www.ingate.com, whose award-winning security products enable enterprises to solve the problem of letting Session Initiation Protocol (SIP) traverse their firewalls, today announced it has achieved "3Com Approved" status in the 3Com Voice over Internet Protocol (VoIP) Solution Provider Program (VSPP).

The "3Com Approved" status is awarded only to those companies whose products have been installed and rigorously tested by 3Com and found to successfully interoperate with 3Com's® secure, converged networking products.

Ingate's debut in the 3Com VSPP program will be showcased at the 3Com booth (#1725) at Networld+Interop 2005. Demos with Ingate Firewall® and award-winning Ingate SIParator® products will be held at the 3Com booth highlighting the products' unique functionalities and interoperability.

Ingate's SIP-enabling Firewalls and SIParators help solve the Network Address Translation (NAT) traversal issues inherent in SIP communications. In addition to near-end NAT traversal, Ingate offers Remote SIP Connectivity, a far-end NAT traversal solution that extends the SIP capabilities of the corporate network to remote workers. Remote SIP Connectivity enhances the mobility of employees significantly by enabling the use of corporate VoIP, IM, etc. from a hotel room, satellite office or even broadband-equipped airplane as long as an Internet connection is available.

"The remote worker is playing an increasingly important role in today's businesses. Ingate's Firewalls and SIParators extend the productivity benefits of IP communications to this growing population, and are unique in the way they deliver this functionality within the enterprise firewall itself while maintaining superior control and security at the enterprise network edge," said Olle Westerberg, Chief Executive Officer, Ingate Systems."Interoperability with the world's leading enterprise vendors has always been a priority for Ingate. We are proud to be a "3Com Approved" solution, as it demonstrates our commitment to total interoperability and in bringing SIP-based mobility solutions to the enterprise."

"We are delighted that Ingate Systems is part of the 3Com VSPP program," said Pat Rudolph, 3Com vice president of technology. "Ingate's technology dovetails nicely with our open standards architecture approach, to provide enterprises with easy-to-install and easy-to-maintain secure, converged networking solutions."
