Product Description
Growing numbers of hams are using VoIP, or Voice Over Internet Protocol, in combination with their radios for long-distance communication spanning hundreds or thousands of miles. They're using the Internet as the relay between their base stations, handhelds and mobile transceivers.
This is a guide to the four primary VoIP systems used by hams: EchoLink, IRLP, eQSO and WIRES-II. The book is designed for beginners who need information on how to set up and use these systems, but it also provides plenty of technical meat for those who want to dig deeper and explore how the systems actually work.

Great Introduction to EchoLink and IRLP December 20, 2008
Matt Neely (Cleveland, Ohio)
ARRL's VoIP: Internet Linking for Radio Amateurs is a great introduction to the various Voice over IP (VoIP) technologies used in amateur radio. The book provides a general overview of the various amateur radio VoIP technologies such as Echolink, IRLP, WIRES-II and eQSO. After a brief introduction to these different technologies the rest of the book focuses on Echolink and IRLP. The author covers the common commands used in each system and how to access Echolink and IRLP systems over the air and through the internet. I really enjoyed the technical details the author provided when explaining how Echolink and IRLP worked. The author also provided a decent amount of information regarding how to setup your own IRLP and Echolink node.
The biggest complaint I have with the book is the price. I feel its a little high given the size of the book and amount of material covered. Additionally the book only briefly mentions WIRES-II and eQSO. I would have liked to of seem more information on these systems.
Overall I enjoyed the book. If you are interested in learning about Echolink and IRLP this book provides a great introduction.

Missing some newer skils and services ... September 6, 2008

This is a good book, it covers the basics of VoIP. However since it has come out there have been some major changes. As only to be expected with computers and radios ... So I give this a 3 / 5, not the best but still good.

I have seen IRLP in action and thought to myself how do I do this? So I searched everywhere and found out that Echolink was the local popular form,but apart from the echolink on-line manual couldn't find much else to help me get an angle on this.
This book has been a welcome book to help me understand all about the subject - it really gives all the resources and information needed to get going.But as always it is not only the book that's important - it is taking action that is the exciting part.
One of our local radio clubs MDRC just had a really successful meeting with standing room only on echolink and it is going to get bigger.I think this book is a good start so you can learn enough to get into it,get your feet wet and get that experience to write the next "update".Petervk4cbd

An easy to understand description and implementation of VoIP radio linking for both the amateur and veteran. The book covers several products available free from the Internet including one product - Echo Link -- creating by the author. If you are looking to try something new with Internet Linking or just understand how it works, this is the book to have by your side.

In VoIP, author K1RFD does a nice job of explaining the technology behind this unique aspect of the hobby. The book details how the various VoIP applications work and includes information on setting up an RF node. A valuable addition to the ham shack for new and seasoned users of voice over IP applications with amateur radio linking.
