This book provides an indepth coverage of the H.323 protocol. This book is a very good choice for profesionals working in H.323 domain.

If you are confused about H.323 and are looking for a book that explains this intricate, convoluted standard, then you are looking at the right book. As an individual who has been involved with the standard from the early days I am very happy that there is finally a book that completely covers the standard in a language that is understood by everyone. This is a wonderful book.

This is a treasure of H.323, VOIP information! Excellent protocol information. This is no paper weight, gathering dust! I use the book and I'm glad to have it on my shelf.

This is by far the most comprehensive book on the market. I agree with the previous review, IP Telephony with H.323 is for advanced uses and a great reference guide as well. I highly recommend it if you want a thorough understand H.323 and IP Telephony, however, if you wish to learn about a particular subject, for example QoS or MPLS, this book will not provide enough detailed information (check out Cisco Press).

Must buy!

This book has definitely provided me a solid background in H323.
In addition, it is a very useful reference, for example, I was
able to follow the call setup and media setup packet flow of an IP phone captured via a protocol analyzer(ethereal), thanks to the very clear illustrations. This is definitely a must for network administrators/managers considering a multimedia network implementation.

This book provides a highly-technical in-depth look at H.323. Aside from reading a few whitepapers on the Internet, this book was my first real introduction to H.323. The subject itself is rather complicated to a new-comer, but this book provided a high level of detail without losing the reader. While it is no "for dummies" book, it is clearly written so the person with the right background (i.e. with a firm grasp on networking and TCP/IP) can pick it up and follow along. So why 4 stars and not 5? It realy has to do with the architectural graphics. In some of the information on the Internet ... , there are some really good architectural graphics that depict H.323. I think the book could be even better if the authors included such an approach.

This book stands head and shoulders above other h323 and voip books. I know, I have 3 others that are gathering dust on the bookshelf. But this one, I have dogeared, marked, highlighted significant number of pages. It has the most detailed examples, explanations and illustrations that offer real-world implementation of h.323, h.245, h.225 and rtp, codecs, and other associated topics involved in voip. This is a must have, the other books are, well, junk.
