BroadSoft Launches Enhanced Desktop Telephony Toolbar With Advanced Call Control Features

Desktop Toolbar Enables BroadWorks Users to Access Advanced Calling Features within Microsoft Outlook and Internet Explorer

Gaithersburg, MD and San Jose, CA, Spring VON, March 14, 2006 - BroadSoft, Inc., the leading provider of VoIP application software, today announced enhanced capabilities to its BroadWorks Assistant-Enterprise Toolbar, a carrier-class desktop communications product for everyday users of Microsoft® Outlook® and Internet Explorer®. The new BroadWorks® Assistant-Enterprise 13.0 allows users to easily access advanced call control features within the Microsoft mail and browser programs, affording service providers additional tools to offer their customers.

A desktop telephony toolbar that is integrated with the BroadWorks® VoIP platform, BroadWorks Assistant-Enterprise is suitable for corporate as well as small office/home office (SOHO) users. The new advanced call control capabilities give the BroadWorks user a pop-up notification when a call comes in, and enables the user to answer the call, place it on hold, send it to voice mail, or transfer it to another party, without leaving the Microsoft application. Additional highlights include click-to-dial capability from the Outlook contact directory and Internet Explorer Web pages, three-way conferencing and caller identification.

BroadSoft acquired the integrated desktop toolbar product as part of its acquisition of CarbonTwelve, a software and multimedia applications developer based in Sydney Australia, in September 2005. BroadSoft integrated the acquired company's client software applications into the company's BroadWorks VoIP client applications product line and has continued to enhance product functionality and expand its customer base.

"The BroadWorks Assistant-Enterprise 13.0 toolbar represents another milestone in our continuing effort to make advanced call features easier to use, to drive adoption of service providers' enhanced VoIP service offerings," said Scott Wharton, vice president of marketing for BroadSoft. "BroadSoft Assistant-Enterprise 13.0 is a valuable tool that packs a collection of convenient voice options into a small space and saves users valuable time. By enhancing our applications with such value-added functionality, BroadSoft is empowering service providers with a growing range of differentiated revenue-producing offerings for their customers."

BroadWorks Assistant-Enterprise will be featured in BroadSoft's booth at the Spring 2006 VON Conference & Expo, Booth 1127, on March 14-16 at the San Jose Convention Center in San Jose, CA. The BroadWorks Assistant-Enterprise toolbar and Deployment Studio are currently available.
