New Ingate SIParator® Brings SIP-capability to Enterprise Firewalls

Unique New Product Brings SIP Communications to the Enterprise LAN While Protecting Firewall Investment

STOCKHOLM, SWEDEN, February 19, 2002 - Ingate Systems, provider of the world's first SIP-capable enterprise firewalls, today announced the release of the Ingate SIParator® 40. The first in a series, the Ingate SIParator® 40 is an add-on that SIP-enables existing firewalls, bringing universal person-to-person Internet communication to the enterprise.

SIP (Session Initiation Protocol) is the IETF protocol that is becoming for realtime person-to-person Internet communications what HTTP is for the web. However, SIP-based communication has been unable to traverse current firewalls and NATs, inhibiting universal connectivity between SIP users on different private LANs. The Ingate SIParator® 40 connects easily to existing firewalls, enabling SIP-based IP communications including presence, instant messaging, IP telephony and audio/video conferencing while preserving enterprise investments in firewall security.

The Ingate SIParator® 40 is the first in a range of SIParators that will be released throughout 2002. Designed specifically for the flexibility, cost-efficiency and scalability needed by small to midsized businesses, this firewall add-on includes a built-in SIP proxy and SIP registrar that dynamically control a built-in NAT router. The Ingate SIParator® 40 connects to the DMZ port of the existing enterprise firewall and handles all SIP traffic.

"With companies including Microsoft®, WorldCom and AOL supporting the SIP standard, the only obstacle to enterprise access to realtime IP-based communications is the necessity for a SIP-capable firewall," said Ingate CEO Olle Westerberg. "Not only does Ingate have the world's first SIP-capable firewall, we offer the alternative option of purchasing an Ingate SIParator®, allowing enterprises to choose their method for scalable, flexible SIP-capability."

Ingate offers small to midsized businesses two ways to achieve SIP-capability. The Ingate SIParator® 40 uses the same innovative technology found in Ingate's suite of firewalls, launched earlier this year. Enterprises that want to take advantage of the benefits of real time person-to-person IP communications have the choice of purchasing an Ingate firewall - the world's first SIP-capable firewall. Those businesses wishing to maintain their previous firewall investment can purchase an Ingate SIParator®, which will SIP-enable an existing firewall. Prior to these Ingate products, VoIP and IP telephony have only been available to enterprises as isolated islands, such as through a corporate Intranet. Ingate is the first company to bring universal, interoperable SIP communication to enterprise LANs.
