BroadSoft Announces First Available IMS-Compliant VoIP Application Platform

IMS Compliance Allows Network Operators to Deploy Next-Generation VoIP Applications Across Wireless and Wireline Networks, Provides Enhanced Flexibility and More Application Offerings

NEW ORLEANS - March 14, 2005 - BroadSoft®, Inc., the leading provider of VoIP application software, today announced that its BroadWorks® platform is the first commercially available VoIP application technology that is IP Multimedia Subsystem (IMS) compliant. The BroadWorks VoIP application platform has already been operationally deployed by two of the world's leading infrastructure providers, Ericsson and Lucent Technologies, in separate IMS-related carrier roll-outs.

The IMS framework is critical to the delivery of multimedia applications by service providers over converged network architectures. By unifying fixed and mobile infrastructures through IMS, BroadWorks allows both wireless and wireline carriers to deliver the same advanced applications over landline, mobile or residential broadband networks. These carriers also gain an open, IP-based infrastructure for next-generation application delivery and network convergence.

A Significant Advantage for All Network Operators
For wireless operators, this represents a significant expansion in their ability to deliver rich multimedia applications including video, messaging, or collaboration features. It also dramatically lowers barriers to entry and accelerates time to market of VoIP services for purely landline-based carriers. These benefits combine to allow an unparalleled opportunity to enhance customer relationships, recapture lost revenue, reduce churn and deploy innovative new applications spread across a substantially larger customer base.

The advanced multimedia application capabilities of IMS and BroadWorks also present a significant advantage for network operators in selling to the enterprise market. By combining the economics of hosted VoIP services with productivity-enhancing features such as instant messaging, presence and conferencing that elevate the value of both landline and mobile devices, service providers can create a powerful value proposition and competitive advantage.

Previously, infrastructure constraints forced communications companies delivering advanced VoIP and multimedia features to create islands of separation. Now, through IMS, mobile and wireline carriers can offer hosted VoIP, PBX, conferencing, instant messaging, or other multimedia features independent of their infrastructure.

"BroadSoft's genesis is rooted in the wireless industry," said Scott Hoffpauir, chief technology officer for BroadSoft. "BroadWorks was designed with the belief that network operators should be able to offer their customers the same variety of innovative applications for their landline phones as they do on their mobile phones."

BroadWorks and IMS Drive Application Innovation
The BroadSoft IMS-compliant solution provides a future-proof architecture that enables a graceful migration to an IP-based network environment. This powerful combination will drive a wealth of new application innovation - regardless of how subscribers access the network.

As part of the IMS architecture, BroadWorks enables multiple applications and operations support systems to share common resources across all networks. As a result, the carrier can offer subscribers access to the same set of IP applications from a single, user-friendly management interface regardless of the network or device used to access them.

"Major carriers operating both wireline and wireless networks no longer need to create separate application pools for each environment," said Danny Klein, senior analyst with The Yankee Group. "With BroadWorks, applications such as hosted PBX can be accessed by desktop and mobile phone alike. Therefore, carriers can bundle mobile services along with landline enterprise or residential applications, setting a new benchmark for offering customers truly converged IP services."
