BACKGROUND:

Founded in March 1998 and located in Santa Clara, Calif., TollBridge Technologies -- selected in May as one of UPSIDE's Top 100 Private Companies -- is the leading provider of high-quality voice-over-broadband solutions to the new generation of carriers. Synergy Research has named TollBridge the market share leader for five consecutive quarters. TollBridge's solutions change the economics of delivering voice services to small-business customers by allowing carriers that own Class 5 switches to use broadband access technologies, such as DSL, cable and wireless, to use alternative technologies in the local loop and deliver toll-quality voice and integrated data services.
