Ingate® Announces VoIP Installations in Japan

Success in Bringing SIP to the Japanese Enterprise Market

FALL 2004 VON CONFERENCE & EXPO, BOSTON, October 18, 2004 - 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, announces several enterprise installations throughout Japan that bring VoIP - as well as other SIP-based realtime person-to-person communications - to business customers.

Live SIP-based person-to-person communications are expected to be the next major wave of Internet usage after email and the Web. However, SIP-based communications do not reach users behind firewalls and NATs automatically. Ingate's fully SIP-capable firewalls solve this problem. In addition to firewalls, the company also produces and sells the Ingate SIParator®, a device that works in conjunction with an existing network firewall to seamlessly enable the traversal of SIP communications.

Ingate's success in bringing SIP to Japan is a reflection of the country.s growing demand for internet telephony, as well as an increasing interest in instant messaging, presence, and all of the SIP-based applications that enhance corporate productivity and demonstrate cost-savings.

"Businesses in Japan are eager to migrate their telephony systems to VoIP," said Olle Westerberg, Chief Executive Officer, Ingate Systems. "The interest for applications based on SIP is especially strong, as the protocol is considered the standard for all these different forms of realtime communications."

The installations were completed via the Japanese systems integrator Bell Net Corp. Bell Net is a principal shareholder of Ingate Systems.
