SIP-Capable Firewalls and SIParators From Ingate Available to Businesses Nationwide

Leading Distributor Interlink Communication Systems Adds Ingate to Growing List of Value-Add Partners

Stockholm, Sweden and Clearwater, Florida - July 22, 2002 - Ingate Systems, producer of the world's first SIP-capable firewalls and SIParators, and Interlink Communication Systems (ICS), a leading Value-Add Distributor, today announced that Ingate's mission critical security products are now available through ICS. www.interlinkweb.com.

Ingate, a Swedish technology company with a 25 year heritage of communications and security technology development, produces SIP-capable firewalls and SIParators (a device that plugs into an existing firewall to seamlessly enable SIP) for enterprises that want the time and money saving benefits of SIP-based realtime communications including presence, instant messaging, VoIP and conferencing.

SIP, or Session Initiation Protocol, is the IETF signalling protocol that allows interoperable realtime communications regardless of who is providing the service. With providers including Microsoft, AOL, AT&T, MSN, Yahoo!, Cisco Systems, Pingtel and CommWorks offering or developing SIP-based product and services, it will only be a matter of time before SIP is for realtime communications what HTTP is for the Web.

However, SIP is a new protocol, which means that existing firewalls will block SIP media streams, keeping enterprises from the benefits of realtime communications. The Ingate Technology will fix this problem and allow SIP to interoperate with existing installed firewalls offering the capability and at the same time protecting the original investment.

"Everyone is talking about enterprise usage of realtime communications, but with concerns about interoperability and security," said Ingate CEO Olle Westerberg. "SIP is solving the interoperability concern, and Ingate is the solution to the security issue. Companies that want to use interoperable realtime communications can either purchase one of Ingate's SIP-capable firewalls or preserve their previous firewall investment by purchasing an Ingate SIParator®."

"ICS has specialized over the years in providing nationwide access to high performance communications and internetworking products, through the channels serving the enterprise space. Customers in the enterprise space today are after technology that provides better application support with very good ROI. If products do not provide for both, customers will simply not invest in them," said Al Higgins ICS President. "That's why we are extremely excited about working with Ingate. Ingate's products clearly address both needs with their inexpensive, easy to use solutions to the SIP-traversal problem and it fits right into the ICS product strategy to offer Ingate Firewalls and SIParators to our customers," said Higgins.

Ingate's suite of Firewalls and SIParators are available in a range of models to meet the needs of the entire enterprise market. All include a SIP proxy and a SIP registrar, support NAT and PAT and have TLS support for encrypted SIP signalling - which means that instant messages are automatically encrypted, eliminating IM security concerns. Additionally, Ingate products are scalable to the needs of today's dynamic enterprises, and are extremely cost-efficient. For about the cost of a laptop, Ingate can bring SIP safely and securely to your enterprise LAN.
