BROADSOFT OFFERS SERVICE PROVIDERS UNPRECEDENTED OUTAGE PROTECTION AND CALL RESILIENCY WITH BROADWORKS' CARRIER-CLASS GEOGRAPHICAL REDUNDANCY CAPABILITIES

BroadWorks' Industry-leading System-level Redundancy Capability Takes the Worry out of IP Voice

GAITHERSBURG, MD, April 9, 2002 - BroadSoft, Inc., the leader in voice applications and servers, today announced that BroadWorks™ now offers the industry's first commercial system-level geographical redundancy solution. This enhancement to the company's flagship product, BroadWorks, solves the reliability challenges facing service providers with a solid new approach to overall system availability in the event of major hardware and network outages. BroadWorks' system redundancy offers 99.999% total system availability, increases service reliability, and has already been commercially deployed by Exario Networks. This level of reliability exceeds that offered by PSTN and can withstand even catastrophic events.

"BroadSoft is doing what no one else can - giving service providers the power to use IP technology to make voice services more reliable," said Nathan Stratton, CTO, Exario Networks. "BroadWorks' system redundancy was a key selling feature for us and we believe this capability is increasing our customer satisfaction and giving us a competitive advantage for maintaining our major corporate customers' mission-critical services. We are already deploying this solution to protect our network and customers from outage and loss of service."

BroadWorks' system redundancy leverages its uniquely distributed client-server architecture which separates intelligent network functions from applications. By deploying servers in a geographically redundant network configuration, BroadWorks provides redundancy and prevents service failure. If one server fails, BroadWorks switches over to the secondary server on a user-by-user basis with no perceptible loss of service. This offers a great improvement over existing solutions. For example, with today's PSTN, when one node goes down, the whole service area goes down. In addition, when there is a network failure in an IP network, the service fails as well. With BroadWorks geographic redundancy, service providers are protected from both server network outages and can therefore offer their customers an unprecedented level of outage protection and voice service availability.

"BroadSoft is helping to take voice application accessibility and resiliency to a new level with its carrier-class redundancy solution. Redundancy capabilities, such as BroadWorks, reduce the challenges service providers face with a single point of failure," said Tom Jenkins, Vice President of TeleChoice, a leading strategic consulting firm. "BroadWorks' architecture and dynamic processing technology offers carriers a commercially deployed, full-system solution that includes redundant networking. This is great news for service providers."

The core of the BroadWorks platform is the Application Server which executes and manages enhanced user and enterprise services such as call waiting, selective call acceptance, and auto attendant. To achieve system level redundancy, Application Servers are deployed in primary/secondary redundant pairs. Under normal operation, the primary Application Server will terminate all calls for its user base. User modifications, additions and deletions are replicated across both the primary and secondary Application Server, making all service and user profiles available on both servers. In the event that the primary application server fails, or is simply inaccessible from one or more endpoints in the network, then those endpoints will be able to route their calls through the secondary Application Server.

"We recognize that today's service providers expect the same level of redundancy and reliability found in legacy TDM network equipment when deploying voice over IP equipment; however, until now they were unable to achieve this," BroadWorks not only addresses the traditional hardware and software reliability requirements, but also provides a proven solution to building a carrier class level service offering that is better than PSTN and other VoIP solutions," said Scott Hoffpauir, co-founder and CTO BroadSoft. "BroadWorks' redundancy features dramatically strengthen the reliability of a carrier's voice services by protecting them against potentially immobilizing collapses of communications systems to ensure continuous voice service. We are pleased that Exario Networks is deploying our industry-leading solution to offer always-on voice applications to its customer base of multinational corporations."

BroadWorks is the industry's first complete set of integrated voice applications and servers designed to enable service providers to deliver basic and enhanced voice services to enterprises of any size. The BroadWorks product family provides support for media-oriented applications such as voice mail, conferencing, and auto attendant, as well as personal calling functions such as selective call forwarding and notification, call transfer, and simultaneous ringing. BroadSoft has announced seven service providers nationwide who are using BroadWorks to add easy-to-use enhanced voice services to their service offerings.

BroadSoft will be showing a live demonstration of BroadWorks in their booth (#1005/1007) at the Spring 2002 Voice on the Net (VON) show in Washington State Convention and Trade Center, April 8-11th, Seattle, WA.
