DESCRIPTION:
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.. 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
"His concept of IP was a nightmare" according to Patrick T. Stingley. The author's background explanation of IP was a nightmare.His insistance that UDP is a member of the TCP/IP protocol suite is such a skewed perspective that it made me wonder if he had any competence with IP at all and made me suspicious of the remainder of the material. If he held this viewpoint for some reason (historical, or otherwise and not simply complete ignorance of the subject matter) I somehow missed t. "A very practical book" according to Jeff Malone. I normally do not write reviews but when I noted a person said this book was for a 'housewife' and gave it one star I thought something was amiss. I found this book to be very practical, with numerous examples that show 'how to do it.' I purchased other books on this topic and found them to be filled with standards literature from the ITU. Thus, I was perplexed how someone could rate this book with one star when. Great book with many application notes I found this book to be a most practical guide to implementing voice over an IP network. In the book the author shows over 20 techniques, many of which are not obvious till you think about them that shows how to make voice a reality. I especially appreciated the authors insight concerning reconfiguring a router's access list. Its obvious the author really knows networking and shows his real life examples through
. The book also has lots of information (and opinions) on specific products and services. 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. 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. --David WallTopics covered: The business case for voice over IP, operational details of the TCP/IP protocol suite, IPv4 and IPv6 packet structure, voice and techno
