BroadSoft's BroadWorks Application Helps Provide Fixed/Mobile Convergence for Midwest Wireless Subscribers

'oneWave' Residential and Business Customers Will Enjoy Advanced VoIP Features Via Both Cellular and Office or Home IP Phones

GAITHERSBURG, MD, June 29, 2005 - BroadSoft, Inc., the leading provider of VoIP application software, today announced that Midwest Wireless has deployed the BroadSoft® BroadWorks® platform. This application will support Midwest Wireless' innovative oneWave, one of the nation's first seamlessly converged mobile/fixed communications services.

Using BroadWorks®, Midwest Wireless is able to offer its subscribers unified phone numbers and pricing plans, as well as enhanced quality in previously determined "dead zones." Additionally, subscribers are in control of how they manage their calls and are able to:

• tap into the same bucket of minutes for their fixed or mobile service
• direct multiple mobile phones to the same broadband phone
• place calls - free of charge - between their mobile and broadband phones

Midwest Wireless is now able to provide added functionality to its wireless customers while simultaneously providing a service that is both fixed and mobile - without the added capital expenditures of building additional cellular towers. In a single platform BroadWorks hosts a comprehensive breadth of enterprise and consumer VoIP applications, including Hosted PBX, IP Centrex, Mobile PBX, Residential Broadband, and Business Trunking.

A single oneWave phone number will unite the Midwest Wireless subscriber's wireless and integrated home or office phone service that utilizes voice over IP (VoIP). The result is a single service with one phone number and one voicemail box shared by the customer's cellular and broadband phones. oneWave also provides the subscriber with a set of features including simultaneous ring, caller ID, call forwarding, call waiting, 3-way calling and Web-based service self-management.

"In today's communications world, it can be extremely challenging for subscribers to juggle multiple services, numbers and voicemail boxes," said Scott Bergs, COO of Midwest Wireless. The company currently delivers wireless telephone and high-speed data services to more than 400,000 subscribers in Minnesota, Wisconsin and Iowa, and ranked No. 25 on NPRG's December 2004 list of Top 150 Wireless Carriers. "With BroadWorks, we are able to transform the competitive landscape with a service that lets callers dial a person rather than a single device or location and remove those restrictions from our customers," added Bergs.

Midwest Wireless' enterprise customers can replace their mobile and/or landline telephone and data services with the oneWave integrated cellular/broadband VoIP and data service. The hosted service will deliver communications and collaboration features not typically available from traditional business PBXs or Centrex services, such as voice VPN, auto attendant, attendant console, call center functions, unified messaging, selective call-forwarding, click-to-dial, conferencing and IP video.

"Midwest Wireless' unique implementation underscores the flexibility and breadth of the BroadWorks platform. This deployment of BroadWorks also represents the first BroadSoft customer that combines both a wireless and wireline product," said Michael Tessler, CEO of BroadSoft. "Together, BroadSoft and Midwest Wireless are setting a new benchmark for converged wireless and wireline services."

The BroadWorks deployment enables Midwest Wireless - BroadSoft's first announced wireless carrier customer - to immediately combine disparate technologies at the services level, paving the way for eventually replacing separate wireless voice and data networks with a unified IP infrastructure. The carrier will replace its traditional circuit-based cellular phone switching with a Session Initiation Protocol (SIP)-based VoIP architecture.

Through SIP, BroadWorks will interwork with softswitches and signaling gateways to enable the sharing of phone numbers and feature sets across cell phones and broadband-connected IP phones. Infrastructure-independent BroadWorks is the first application server compliant with emerging IP Multimedia Subsystems (IMS) fixed/wireless convergence architecture standards.
