Today's Internet does far more then email and file transfers. Initially designed
for non-real-time (NRT) data applications, the Internet has matured far beyond these
tasks. In addition to web browsing, online imaging, and chat rooms, we now expect
the Internet to deliver such real-time (RT) media as streaming music, video, and
Internet phone calls directly to our homes and offices.
Presently, Voice-over-Internet Protocol (VoIP) is all the buzz-but it's more than
just talk. VoIP technology has matured. Not only is it the latest hot new Internet
application. Today, VoIP has emerged as a reliable technology that is commercially
viable, competing (and winning) against traditional phone services in business and
consumer-class markets.
