TELICA AND BROADSOFT STRENGTHEN PARTNERSHIP WITH COMMERCIAL DEPLOYMENT OF INTEGRATED IP VOICE AND DATA SOLUTION

BroadSoft Becomes Premier Partner in Telica's Total Solution Alliance Program

Marlboro, MA and Gaithersburg, MD - November 11, 2002 - Telica™, Inc., a leading provider of softswitch-based voice and data infrastructure products for today's evolving telecommunications network, and BroadSoft®, Inc., the leading provider of voice applications and servers, today announced that the two companies have strengthened their partnership with their first commercial deployment of a combined solution: Digital Agent, a facilities-based provider of communications services for businesses.

With this customer deployment, BroadSoft has become a Premier Partner in Telica's Total Solution Alliance Program. To achieve the Premier Partner level, BroadSoft's BroadWorks™ voice application and services solution and Telica's Plexus™ 9000 voice packet switch engaged in rigorous field interoperability tests to provide enhanced IP-based hosted voice services such as IP Centrex and IP VPNs that utilize the SIP interface definition. Telica's Total Solution Alliance Program provides carriers a framework for certified interoperability guaranteeing end-to-end Class 5 and Class 4 solutions for TDM, IP and ATM voice infrastructures.

Using the combined BroadWorks-Plexus 9000 solution, Digital Agent can now offer small and medium-sized businesses in Georgia hosted private branch exchange (PBX) and IP Centrex services.

"Telica is a recognized leader in providing softswitch-based voice and data products to service providers. BroadSoft is very pleased to become a Platinum Partner in their Total Solution Alliance Program. Such programs are critical to speeding the adoption of SIP-based integrated voice and data solutions," said Michael Tessler, president and CEO, BroadSoft. "We look forward to further collaborative efforts."

BroadWorks is the industry's first integrated system of voice applications and servers enabling service providers to deliver basic and enhanced voice services to enterprise. BroadWorks' voice and media servers and telephony applications enable service providers to rapidly and cost-effectively deploy a comprehensive portfolio of carrier-class telephony applications such as IP Centrex, hosted PBX, voice VPN, and enhanced network applications. Using BroadWorks, service providers and customer administrators can manage administrative functions with BroadSoft's patented web-based portal, CommPilot. The BroadWorks architecture can scale to support millions of subscribers and delivers 99.999% total system availability.

Telica's Plexus 9000 is a carrier-grade switch that includes all the elements of a softswitch-based solution, media gateway, media gateway controller and signaling gateway, to provide Class 4/5 switching for the PSTN as well as ATM and IP networks. These various softswitch components may be deployed in either a distributed, centralized or integrated configuration to meet a wide range of network requirements. A single Plexus 9000 shelf supports up to 137,088 ports for TDM applications and up to 24,192 simultaneous calls for voice over packet applications independent of IP or ATM packetization. The unparalleled scalability and architectural deployment options provide the highest level of flexibility for service providers.

"BroadSoft is a very successful and innovative company. Telica has been working closely with BroadSoft for two years and to see our collaborative efforts realized and live in a customer network is very exciting," said John St. Amand, president and CEO of Telica. "The entire industry has been working towards a true converged model and we consider this deployment with BroadSoft a significant step towards that goal."
