VocalTec's Packet Tandem Switching Solution

Prepares Data Access to Compete in Deregulated Indian Market

VocalTec(R) Communications Ltd. (Nasdaq: VOCL) (VocalTec), a leading telecom equipment provider offering packet voice solutions for carriers and service providers, today announced a multi-million dollar deal to deploy its packet tandem switching equipment with long distance provider Data Access. Data Access is among the first licensed international long distance operators in India following the country's April 1 deregulation. It is also the second largest gateway Internet service provider in India and provides more than 50 percent of the bandwidth requirements for ISP's in India.

Data Access is purchasing VocalTec's packetized telephony solution in anticipation of the deregulation of its principal market in India. "VocalTec offers Data Access the ability to capture revenue and market share through the rapid deployment of high quality voice services," said Siddhartha Ray, CEO at Data Access. "A true turnkey solution, VocalTec equipment allows us to immediately offer new services without the delay and expense of a traditional network build-out."

Optimized Solution for Deregulating Markets

India is one of several countries deregulating its telecommunications laws in 2002. As more and more currently regulated countries open up to international competition, carriers will look to deploy VoIP networks based on equipment such as VocalTec's due to its high quality, low initial investment requirement and rapid deployment capability.

"Similar to what we have seen in other deregulating countries, we expect the opening of the Indian market to trigger overall market growth, primarily due to reduction in prices. As a result, both new and incumbent carriers will have the opportunity to grow their voice business," said Elon Ganor, CEO and chairman of VocalTec. "VocalTec's field-proven equipment and hands-on experience with an extensive variety of telecom protocols and network environments in over 100 countries will be key factors in enabling Data Access to switch on their voice network rapidly and cost effectively. Our packet tandem switching solution allows Data Access to offer new services immediately in order to capture market share in a newly competitive market."

Unsurpassed Interoperability and SS7 Capabilities

VocalTec's packet tandem switching solution provides interoperability with 60 percent of the world's VoIP ports, allowing newly established carriers to generate revenues instantly upon deployment. The VocalTec VoIP equipment has been installed into five points of presence (POPs) in Data Access' Network of the World. The unsurpassed SS7 capabilities, including support for over 50 national SS7 variants, and proven scalability of VocalTec's solution facilitates international deployments and network growth.

Expanding Presence in India

VocalTec has additional equipment installed in India through ITXC's SNARC(SM) program. Over one billion minutes have traveled over ITXC's global telecommunications network from its SNARC program. ITXC SNARCs are ITXC-owned and operated IP telephony equipment co-located at a qualified, licensed carrier's premise. SNARCs convert calls between circuit-switched networks and IP, enabling carriers to receive competitive rates and earn additional revenue for completing phone calls from around the world.

In order to provide local integration services, VocalTec has established a cooperative business relationship with Nirvan Management Group, a leading provider of professional services to the Indian telecom market. Nirvan markets next generation telecom products and provides complete solutions to carriers and service providers.
