Ingate and Excel Telecommunications Demonstrate Seamless Interoperability

– Speeding Deployments of Excel VoIP Service with Ingate’s NAT Traversal, SIP Trunk Solution

HOLLIS, NH and IRVING, TX – October 2, 2007 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, and Excel Telecommunications, a leading provider of long distance, data services and other communication services to businesses through resellers and telecommunications dealers worldwide, have demonstrated full interoperability between Ingate Firewalls, SIParators and Excel Voice-over-IP (VoIP), Internet and data communications solutions.

Ingate’s award-winning Ingate Firewall® and Ingate SIParator® products make it possible for Excel customers to connect their IP-PBX to the Excel service by solving the Network Address Translation (NAT) traversal issues with the SIP protocol while maintaining the security and integrity of the network. In this manner, Excel users can utilize their corporate VoIP, IM, and other IP-PBX capabilities from any remote location, as long as there is Internet access.

Ingate’s solutions also allow Excel customers to utilize SIP trunks. SIP trunks rapidly reduce costs by eliminating the need for an enterprise PSTN gateway, unused BRI/PRI capacity, expensive and underutilized phone lines or trunks at remote offices, and by providing PSTN termination in the local area.

“Ingate is proud to be working with leading VoIP provider Excel Telecommunications in offering secure NAT traversal and SIP trunking solutions for Excel’s global customer base,” said Steven Johnson, President, Ingate Systems. “With Ingate’s technology, Excel can offer its business customers and resellers one-stop shopping for VoIP, remote connectivity and SIP trunking solutions.”
