Move real-time voice conversations over data networks NOW! Gateways that can transmit voices over data-intensive IP networks will soon give way to translation software that can send voice, fax and video over the Internet. Get a head start on this revolutionary technology with Gilbert Held's Voice &amp; Data Internetworking. Learn how to take advantage of your existing network to make voice calls to and from multimedia-capable PCs, and how to use videoconferencing over existing data networks. You get hands-on guidelines for voice compression and making your transmissions secure from internal and external intruders. Explanations of bandwidth allocation and its importance in voice transmission, the discussion of Voice-Over Frame Relay and Voice-Over IP, and recommendations on equipment available from major vendors round out this up-to-the-minute field report on one of today's most momentous communications trends.
