According to IDC, the VoIP market is projected to grow at 50% per annum on a conservative basis for the next five years. By 2005 over 20% of all calls will occur over the Internet or corporate intranets. Gateways that can transmit voices over a company's otherwise data-only IP networks are expected to serve as precursors for translation software that will send voice, fax, and video over the Internet. Networking expert Gil Held shows network managers techniques that can be used to transport real-time voice conversations over networks designed for data transmission. Features of the book include: applications notes in each chapter showing how to implement the technology, such as how to route call centre calls over an IP gateway; cutting edge material on voice over IP gateways and QoS (quality of service), including why it's needed, and how it can be obtained; and in-depth explanation of how to transmit voice over private IP networks, the Internet and intranets.

High-speed networking infrastructures have immense potential, but most organizations don't take advantage of it. Voice and Data Internetworking tries to bridge the gap by showing you first of all how to configure your Internet Protocol (IP) networks to handle real-time voice conversations. About half of the book addresses academic (but important) material, including the suitability of IP and Transmission Control Protocol (TCP) to voice and the various approaches to the problem of digitally encoding human speech. When the text digs into specific mechanisms for transporting voice over networks designed for data traffic (Frame Relay and ATM particularly), specific configuration instructions are skimped on in favor of how the protocols work and how they need to be adapted to the special characteristics of voice, in addition to the economics of voice over IP. There are charts that show how the cost-effectiveness of such systems grows with call volume, plus other charts that show how much time typical employees spend on the phone. This material would be useful in a feasibility study of voice over IP for a large enterprise. The book also has lots of information (and opinions) on specific products and services. --David Wall
Topics covered: The business case for voice over IP, operational details of the TCP/IP protocol suite, IPv4 and IPv6 packet structure, voice and technologies for digitally encoding it, Frame Relay, and Asynchronous Transfer Mode (ATM).From the Back Cover:
