Product Description
Integrate voice and data into one system, and you can save your company thousands of dollars. Networking expert Gil Held shows you hands-on techniques that can be used to transport real-time voice conversations over networks designed for data transmission. Includes new material on the latest technologies, such as Voice over IP and Voice over ATM.Amazon.com Review
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).
This book trys to use simple language to explain many complicated topics, and it fails to expain well. The author is knowledgable on telephone operations, but other than that, don’t expect to learn anything from this book. I want to learn more about VOIP/ATM, H.323, CELP, but I feel very very disappointed after read through the whole book. If you’re a design engineer, don’t expect to learn angthing from it. If you’re a high school student, or a household wife, this may be a good book.

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 that.
The editing was atrocious, which didn’t help at all.
The author provides his e-mail to give comments and feedback, which I tried to do when I found that I had so many notes and errata that I was having trouble writing them all down in the book’s jacket. However the e-mail addresses given for the author are no longer working. (Perhaps wisely!)
The first 3 chapters were a garbled intro to IP.
The sections on speech production and digitization in Chapter 4 were very good. Chapter 5 on telephony was a good chapter. Chapter 6 included a nice simple explanation of SIP.
Chapter 7 was about VoIP equipment which is probably OBE.
Chapter 8 was a complete joke. Explaining ping and traceroute, which should probably have been covered in the beginning sections on IP, but which most likely was boiler plate from other publications by this author.
I got this book free from Cisco and it was worth every penny.

In the summary of book’s introduction, it looks like filling with lots new technologies, i.e. H.323, IP/ATM, and says to be suited for netowrk administrator, engineers. It’s hard to believe only 4 or 5 pages can cover such topics. I strongly feel I am deceived. For entry level engineer or marketing persons, this book may be good. But for those engineering persons, I suggest you to forget this book.

I was impressed that the author covered many key implementation issues throughout the book. This was really helpfull as I’m in the process of developing an integrated solution for my company.

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 numerous examples in the book.
