Ingate® To Introduce Firewall 1900 and SIParator 90 at Spring VON

SIP-Based VoIP, NAT Traversal and Security for Large Enterprises

HOLLIS, NH -- March 6, 2006- >Ingate® Systems (www.ingate.com), which develops firewall technology and products that enable SIP-based live communication for the enterprise while maintaining control and security at the network edge, will unveil new hardware designed specifically for large enterprises at Spring VON in San Jose: the Ingate Firewall® 1900 and Ingate SIParator® 90.

With the greatest capacity of Ingate's full line of Firewalls and SIParators, the 1900 and 90 offer large corporations complete support for IP communications based on SIP, including VoIP, IM and video applications. They solve the Network Address Translation (NAT) traversal issues inherent in SIP communications, and allow for both far- and near-end NAT traversal to extend the SIP capabilities within the corporate network to remote workers.

Both products feature Ingate's SIP proxy technology, which delivers maximum control over SIP signaling, traffic and network security, creating one truly converged network for both data and VoIP. With Ingate products, enterprises can use VoIP and other live communications on the LAN and globally over the Internet or private IP networks.

Capacity and Features

Both the Ingate Firewall 1900 and SIParator 90 have eight interfaces, of which two are mini Gbic that can be used for fiber optic interfaces giving greater flexibility and offer 2600 Mbit/s throughput. The new products are capable of handling 1200 concurrent VoIP calls (e.g. RTP sessions).

The 1900 and 90 include 50 SIP user licenses that can be used for the registration of SIP users on the built-in SIP registrar. Twenty-five SIP traversal licenses are also included, allowing up to 25 calls to traverse the firewall simultaneously. Additional SIP user and traversal licenses can be purchased at any time.

All Ingate Firewalls and SIParators are fully featured, supporting stateful inspection and packet filtering with rules defined and maintained by the network security administer utilizing the GUI. They include an encrypted Virtual Private Network (VPN) termination module. In addition to complete support for SIP, Ingate Firewalls have a proxy for all standard protocols including TCP, UDP, FTP and DHCP.

"The Ingate Firewall 1900 and SIParator 90 address the capacity requirements of the largest businesses," said Olle Westerberg, Chief Executive Officer, Ingate Systems. "Our customers need SIP-based solutions that are reliable, scalable, and secure. We've raised the bar in the industry with our security products including a full SIP proxy, which delivers an unprecedented amount of control and security for IP traffic."

Encrypted VoIP Calls

Ingate supports encrypted RTP (Realtime Transport Protocol), which provides a high level of security for live data with advanced encryption, confidentiality, message authentication, and replay protection. Encryption makes it almost impossible for eavesdroppers to retrieve the original media stream from the encrypted stream.

In addition, both the Firewall 1900 and SIParator 90 support Transport Layer Security (TLS) for secure SIP signaling. When combined with encrypted RTP, these protocols further shield users from eavesdroppers, hackers and spoofers.
