CommuniGate Pro Internet Communications platform sets a new performance standard for Application Servers with proven quality and performance benchmarking from independent CT Labs

Over 220,000 active users on a two-server CommuniGate Pro All Active Cluster with SIP Farm specialization were supported without a single call or registration failure during the test period

Mill Valley, CA – February 20, 2007 – CommuniGate Systems, the leader in scalable Internet Communications solutions, today announced the establishment of an industry-leading performance and quality benchmark and has disclosed the results in a report from CT Labs, the converged communication industry’s most recognized independent testing lab. CommuniGate Pro continues to publicly demonstrate its leadership in performance, scalability, and trust in the company to deliver.

This independent benchmark from CT Labs sets the bar for massive scalability and quality of service for large scale deployments of IMS, VoIP applications, and presence services. CommuniGate Pro’s unique technology delivers Rich Media enabled Internet Communications that drives user adoption and provides flexibility in the applications and services that carriers require.

CT Labs emulated an active subscriber base of unique SIP user agents engaging in real-world call activities. This was accomplished by generating realistic levels of SIP endpoint registrations, peer-to-peer VoIP calls, and application server traffic for various sizes of an active subscriber base.

For each tested CommuniGate Pro configuration, CT Labs discovered the maximum number of subscribers that could be supported without failed calls, excessive call answer or application navigation latencies, detectable voice or application prompt quality issues, or other types of service degradation that would be deemed unacceptable by a typical user. The duration of each test varied depending on the goal and the traffic conditions created. Longer tests were executed to assess the long-term reliability of the CommuniGate Pro architecture.

In the CT Labs test, CommuniGate Pro was found to provide excellent overall performance when subjected to the CT Labs real-world residential traffic model. This two-server CommuniGate Pro All Active Dynamic Cluster configuration, utilizing an external NAS device for shared storage, supported over 220,000 active users without a single call or registration failure during the test runs. The test provides strong validation for service providers that CommuniGate Pro is a platform that can be trusted to perform under demanding conditions.

In a second phase of the benchmark with only a single server environment, CT Labs tests verified that the CommuniGate Pro product supports a large subscriber base on a single low-cost server. This was proven through an examination of the performance results for call connectivity, registrations, and voice prompt quality. With a resulting call throughput of 7,200 calls per hour, the CGP call processing architecture was found to perform reliably during peak traffic conditions.

“These excellent results have relevance to subscribers with accounts on a busy system typical of an ITSP environment,” said Chris Bajorek, Director of CT Labs. “CommuniGate Pro All Active Dynamic Cluster and SIP Farm were found to be extremely reliable workhorses under sustained traffic loads. The SIP Farm call processing engine performed very well even during peak traffic conditions, delivering high levels of call connectivity and reliability.”

“CT Labs has demonstrated once again that the CommuniGate Pro Dynamic Internet Communications platform is recognized as the most scalable and trusted solution, enabling new services and subscriber retention within carriers,” said Jon R. Doyle, Vice President of Business Development for CommuniGate Systems. “The unique architecture provides economic and flexibility benefits not found in complex multi-vendor application architectures. By simply adding nodes to the Dynamic Cluster, carriers are able to achieve effectively unlimited scalability with the best QoS from the most reliable vendor.”

For nine years CT Labs, an independent operating unit of Empirix Inc., has provided automation-based tests that help manufacturers verify performance and rated capacities for their next-generation network products. Examples include verifying performance under ultra-high density traffic levels, including voice quality, packet performance, and reliability for VoIP- and IMS-enabled carrier grade as well as enterprise devices. CT Labs is well-known for its automation-driven real-world performance testing methodologies.

CommuniGate Pro is recognized as the clear 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 multi-million user sites 99.999% uptime and a “rolling updates” 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.
