DESCRIPTION:
Once a guest on telephone lines, the Net now threatens a takeover of its host's principal function: voice-to-voice communications. In Voice Over IP Networks, you'll learn everything you need to: transmit real-time voices over the Internet; understand the technology and its costs; compare leading vendors and their Internet telephony products - 3Com, Motorola, Lucent, VocalTec, Vienna Systems, Nuera Communications, and more; evaluate advantages of the IPv6 and IPv4 protocols; use RSVP, RTSP, IP Multicast, SONET, ATM, and other technologies for telephony; apply Codecs to voice digitization; emulate T1/E1 trunks; implement a system with appropriate standards; and anticipate trends and new products from innovative companies such as QWest.. For intrabusiness use
--Robert Frankland. Broadband packets are covered in chapter 6. This book will help anyone planning to implement telephone service using VoIP determine which technologies to use. The first chapter covers Internet Protocol version 6 (IPv6), and is followed by chapters that explain Resource Reservation Setup Protocol (RSVP), IP Multicasting, and Asynchronous Transfer Mode (ATM). In Voice over IP Networks, Marcus Goncalves provides an in-depth look at the technologies available and solutions provided by a wide range of suppliers. A good general understanding of telephony technology is recommended for readers of this book. The CD-ROM that comes with the book contains product information from ABL, Telogy, and Nuera, including many white papers on VoIP technology. The second part of the book covers codecs and evaluates offerings from a

A Customer I made the grave mistake of purchasing this book, thnking that I would get some decent information regarding the topic of VoIP. What I received was a summarization of the differences between IPv4 and IPv6, outdated chapters on ATM (two of them, one of which the author didn't even write!) and solitations for the author's other book covering IP Multicasting. The editing of the book was absolutely the worst that I have seen - my 7th grader can edit better than this.

Extremely poor book A Customer I too was extremely disappointed by this book. It neither met my Marketing needs (I'm a Product Manager for a large telecommunications company) nor my technical needs (I'm a former telecommunications developer). I'm frankly surprised that there are some good reviews for this book here, as I can't see how this meets the needs of any target audience. In fact, I am going to write a complaint letter to the publisher today.Below are more specific criticisms.It did not job of giving the big picture of VoIP and the associated technologies at all, instead going into extreme details on some related topics. "A nice book for someone who need to sell or buy products" according to A Customer. I agree to other reviewers that obviously the author does not understand anything about VoIP technologies. I think the author made this book based solely from online archives (RFC, ATM Forum, IETF, etc.). Based on his background, I think the author only has knowledge of Windows NT networks and never has a solid understanding of VoIP technologies.If you need an introduction to VoIP technologies, I suggest you read "Carrier Grade Voice over IP" by Collins. If you are a technician or an engineer, you will find Collins' book is useful. If you are a student or someone with a little or no prior knowled
