Ingate SIParator® passes Interoperability Testing with Broadsoft's BroadWorks

SIParator® will enable BroadWorks' customers to utilize SIP-based communications through enterprise firewalls

Stockholm, Sweden - August 21, 2002 - Ingate Systems, producer of the world's first SIP-capable firewalls and SIParators, and BroadSoft®, Inc., the leader in voice applications and servers, today announced that the Ingate SIParator® successfully interoperates with BroadSoft's award-winning BroadWorks. The joint solution will allow businesses to pass SIP-based communications through common enterprise firewalls.

Existing enterprise firewalls block SIP media streams and prevent enterprises from the time and money-saving benefits of real-time communications. The Ingate SIParator® solves this problem by connecting to the enterprise firewall - seamlessly allowing SIP traversal while protecting the company's firewall investment. By using the SIParator® in conjunction with BroadSoft's BroadWorks enterprises with existing firewalls can have access to SIP-based communications such as voice mail, conferencing, and auto attendant as well as personal calling functions such as selective call forwarding and notification, call transfer and simultaneous ringing. BroadWorks is the industry's first complete set of voice applications and servers designed to enable service providers to deliver basic and enhanced voice services to enterprises of any size.

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

"The flexibility and ease of use that SIP offers are paving the way for a host of new communications services and capabilities that will help businesses improve efficiency, productivity and profitability" said Scott Wharton, BroadSoft's vice president of marketing. "As VoIP more widely incorporates SIP, our interoperability with the Ingate SIParator® will allow our customers to have the same carrier-class scalability, maintenance, reliability, with the added benefits of traversing enterprise firewalls."

"BroadSoft's leadership position in IP Centrex and telephony voice applications combined with Ingate's ability to bring SIP to the enterprise is furthering our mission of bringing the time and money-saving benefits of SIP-based communications easily and cost-effectively to enterprises of all size," said Olle Westerberg, CEO of Ingate Systems. "Our successful passage of BroadSoft's interoperability testing shows just how easily Ingate can bring SIP securely to the enterprise."
