LEADING TELECOM VENDOR TO INTEGRATE BROADSOFT'S APPLICATION
SOFTWARE TECHNOLOGY INTO MULTIMEDIA PLATFORM

BroadSoft Application Enables Hosted PBX and IP Centrex in Fixed and Mobile 3GPP Networks

GAITHERSBURG, MD, June 15, 2004 -- BroadSoft Inc., the leading provider of network communications platforms, today announced that Ericsson (NASDAQ:ERICY) and BroadSoft have signed a global OEM agreement to integrate components of BroadSoft's BroadWorksâ technology into Ericsson's IMS based Engine Multimedia 2.0 (EMM 2.0) solution. This integration will enable service providers for the first time to use the same platform to offer a uniform package of advanced managed communications services across wireline and wireless networks based on the Third Generation Partnership Project (3GPP) architecture.

Ericsson will market the EMM 2.0 platform with integrated BroadWorks technology as part of its Softswitch offering, which is based on the 3GPP architecture. With this solution, Ericsson's customers will be able to deliver multimedia services, including hosted PBX, IP Centrex, residential broadband and collaborative conferencing services, transparently across different networks.

The integration of the BroadWorks media and application servers into EMM 2.0 is based on the Session Initiation Protocol (SIP.) It follows the architecture developed for 3GPP that will be used in next generation fixed and mobile networks to provide multimedia services regardless of location.

"By working with Ericsson, we're helping operators to keep their core technologies and investments in place, while enhancing their ability to offer hosted multi-media services across multiple networks based on the 3GPP architecture," said Michael Tessler, CEO and president at BroadSoft. "This announcement further confirms BroadWorks commitment to working with industry leaders to successfully penetrate new market segments."

ABOUT ERICSSON'S ENGINE MULTIMEDIA
Engine Multimedia 2.0 (EMM 2.0) is an all-IP SIP based solution with which an operator can offer carrier class broadband IP telephony and IP Centrex services. It also supports multimedia features such as video calling, presence and instant messaging.

There are three main values with EMM. Firstly, an operator can with EMM enter the lucrative enterprise market by offering IP centrex functionality and thus find new revenues. Secondly, the operator can effectively compete with new operators by offering IP telephony to residential users. Thirdly, EMM is built according the IMS standard, specified by 3GPP, which is the only SIP-based standard for fixed and mobile applications. This allows the solution to be very flexible and scalable. It is also using the same platform as the Ericsson mobile solutions, Instant Talk and weShare, which enables technological synergies, in the form of lower CAPEX and OPEX, between the fixed and mobile applications.
The centralized server architecture of Engine Multimedia will ensure carrier-class QoS and security as well as flexible charging possibilities.
