CommuniGate Systems Reveals Industry-Leading Performance Test for IMS Internet Communications

The Joint Project Profiled a Large Mobile Carrier With 25 Million Subscribers Utilizing the CommuniGate Pro Dynamic SIP Farm Application Server

MILL VALLEY, CA -- (MARKET WIRE) -- March 20, 2007 -- CommuniGate Systems, a leader in Rich Media Internet Communication solutions, today announced results of a massive scalability profile.

The company's IMS solution running on the IBM System z mainframe was tested at IBM's lab in Montpelier, France. The solution demonstrated the high performance and scalability required by carrier environments that support millions of concurrent accounts and use multiple forms of Internet Communications.

The service and clustering capabilities of CommuniGate Pro SIP Farm, paired with the reliability and efficiency of the IBM System z mainframe, provide the IMS architecture that service providers are seeking to support both current subscriber levels and future growth of VoIP and other IP Communications Services.

The joint solution offers carriers a foundation that allows subscribers to access applications and services switching from one network to another with one account for all forms of communications.

The System z mainframe demonstrated excellent overall scalability as the number of Linux virtual machines tested was increased to a maximum of 20 running the CommuniGate Pro SIP Farm Dynamic Cluster under z/VM, the mainframe virtualization technology. As the number of virtual machines was increased, the throughput increased near-linearly. z/VM enabled very efficient utilization of mainframe resources while meeting throughput objectives with a growing workload.

"Our carrier customers are building the IMS infrastructure and applications that will change how we communicate and become mobile, free of location and toll-based models of the legacy telephony network. Time is of essence to them in building new Rich Media Services to generate new revenue streams and increase customer retention as network access becomes commoditized," said Jon R. Doyle, vice president of business development at CommuniGate Systems. "The z9 platform and CommuniGate Pro help to minimize risk and meet the ROI objectives of the carrier for CAPEX and OPEX."

"Carriers are steadily moving to Internet-based communications and converging their networks, be it Wireless, legacy wireline, or Internet-based," said Jim Pertzborn, vice president, Telecommunications Industry, IBM Systems and Technology Group. "Building out massive SIP-based VoIP networks requires trusted vendors with proven technology. This performance test demonstrates CommuniGate Systems and IBM can scale to meet carrier requirements."

CommuniGate Pro is recognized as the leader in providing carriers with Rich Media applications and mobile solutions that increase the subscriber value potential and increase retention rates. The all-active dynamic clustering provides multimillion user sites 99.999% uptime and a rolling update capability that no other platform is able to maintain. CommuniGate Pro is the first real-time Internet Communications platform to offer subscribers access to a single source for e-mail, collaboration, voice/video and mobile Internet Communications. CommuniGate Pro allows subscribers a choice of clients -- IP phones, soft clients, traditional telephony, mobile devices, browsers and IM agents -- all through a single account.

CommuniGate Pro also supports the IBM System p platform and is planning to test rich media applications running on its SIP application server on IBM BladeCenter and IBM System x servers in the near future.
