Brix Networks (www.brixnet.com), the trusted provider of real-time service assurance solutions for real-time networks, today announced it has secured its tenth customer in the last 10 months as Net2Phone, Inc. (NASDAQ: NTOP), a leading provider of voice and enhanced Internet communications services, has deployed the Brix System service assurance solution to verify the quality of its Voice over Internet Protocol (VoIP) backbone infrastructure and services.

Using its advanced IP network and technologies, Net2Phone routes voice, fax, and other value-added applications for consumers, businesses, and carriers worldwide. Founded in 1995, Net2Phone's IP network allows users to place low-cost, toll-quality phone calls using traditional telephones, personal computers, or Internet devices. With millions of global users, Net2Phone routes millions of minutes daily over the Internet, and has become a viable, cost-effective alternative to traditional calling.

"Quality-of-service is essential to the ongoing acceptance and adoption of VoIP for mission-critical applications," said Marty Wolfson, director of QoS at Newark, N.J.-based Net2Phone. "By making the comprehensive Brix System an integral part of our network infrastructure, we can offer our customers high-value services based on measurable, proven, call quality."

The award-winning Brix System is a seamlessly integrated hardware and software solution that is the industry's first complete monitoring and measurement offering designed specifically to address the IP performance management challenges facing organizations today. It consists of a family of hardware appliances, including the Brix 100 (TM) Verifier and the Brix 1000 (TM) Verifier, that are pervasively deployed throughout a network and are tightly coupled with the BrixWorx (TM) carrier-class, central-site software system.

"Advanced applications like VoIP are placing significantly larger loads on networks today than ever before, while also requiring much higher performance and tighter tolerances," said Tom Pincince, president and CEO of two-and-one-half-year-old Brix Networks. "Having an industry leader like Net2Phone as a client is particularly noteworthy for us. Being able to secure 10 customers in less than a year, including some of the largest and most successful names in the carrier, service provider, and enterprise markets, is also testimony to the inherent value of our products and the hard work of our team."
