BROADSOFT TO RESELL CARBON TWELVE'S WORLD-CLASS ATTENDANT CONSOLE AND OUTLOOK/INTERNET EXPLORER VOIP TOOLBARS

BroadSoft's Third-Party Developers Program and Open Client Interface Seed Market with Enhanced Applications that Blend Seamlessly with End Users' Everyday Routines

SAN JOSE, CA - VoIP Developers Conference, August 3, 2004 - BroadSoft, the leading provider of network communications platforms, today announced that it has signed a reseller agreement with Australia-based Carbon Twelve®. Under this agreement, BroadSoft will market, sell and support worldwide Carbon Twelve's miPA Lite® and miRECEPTION® end-user software applications that interface to the BroadWorksâ platform - the most widely deployed solution for hosted PBX, IP Centrex and residential broadband services.

The reseller agreement builds on the companies' long-standing relationship forged in the BroadSoft Third-Party Developers Program, the first developers program for hosted VoIP. Based on the strong response from the market to Carbon Twelve's solutions, BroadSoft has expanded this relationship to promote miPA Lite and miRECEPTION to its customers.

miPA Lite fully integrates all of the BroadSoft CommPilot™ client functionality into a call control toolbar embedded in Microsoft® Outlook® and Microsoft Internet Explorer®. Merging voice and web-based communications into a single application, miPA Lite lets users click on icons within these Microsoft applications to control all their advanced voice features, such as selective call forwarding and do not disturb, voicemail to email, and simultaneous ring. Users can also click on phone numbers in Microsoft Outlook or Microsoft Internet Explorer to automatically initiate calls from their regular or IP phone.

miRECEPTION is a premier, PC-based attendant console that ensures companies give their customers the best first impression. Based on extensive time and motion studies, miRECEPTION is designed to provide receptionists with a vivid and ergonomic interface that is easy to learn and use for increased productivity. For example, receptionists can instantly determine an employee's availability status to provide immediate feedback to callers and visitors. miRECEPTION is also well suited for receptionists that are shared among multiple companies. Receptionists can see which company incoming calls are designated for and answer accordingly.

The BroadSoft Third-Party Developers Program provides everything necessary for third-party application development including training on the BroadSoft platform, sample source code, design consultation, joint sales and marketing support, and access to the BroadSoft extranet and user groups.

"MiPA Lite and miRECEPTION owe a great deal to BroadSoft's developers program and open platform which enabled us to concentrate on our design expertise," said George Lawson, CEO at Carbon Twelve. "This partnership has given us access to the largest customer base in this sector which has been crucial for us to help sell our products. BroadSoft has shown time and again, their ability to deliver best-of-breed solutions to their customers. We see this agreement as another demonstration of that capability."

"We are pleased to partner with Carbon Twelve to offer our customers fresh and intuitive client and console interfaces that enhance users' experience and productivity," said Scott Wharton, vice president of marketing at BroadSoft. "BroadSoft launched its developers program to make it easier for talented developers like Carbon Twelve to leverage their core competencies and quickly get to market with exciting, new solutions. Today's announcement demonstrates that our strategy is working."

BroadSoft will demonstrate the BroadWorks Open Client Interface and Carbon Twelve's miRECEPTION and miPA Lite at the VoIP Developers Conference in San Jose, CA at booth number 204.
