WHAT:       The nation's leading Voice over Internet Protocol (VoIP)
            companies will launch a new initiative to promote a policy
            environment that allows VoIP to deliver its many benefits
            to consumers and businesses alike. More than a dozen
            companies will be represented. The coalition will also
            announce a series of policy principles and advocacy plans
            for allowing VoIP innovation to flourish.

WHY:        In recent months, VoIP has become the most talked-about
            facet of the telecommunications, Internet and technology
            industries; from 200,000 U.S. consumer users today, the
            number of VoIP consumers has been projected to grow
            seven-fold between now and 2007.

            This effort is particularly timely because the Federal
            Communications Commission and several states are actively
            considering a number of VoIP related policy issues that
            could prevent Americans from enjoying the full promise and
            potential of VoIP. However, with the right policy balance,
            Americans can enjoy lower prices, innovative new services,
            and advanced communication features. The Coaliton is
            committed to seeking a policy environment that allows
            VoIP to succeed.
