Editor's Notes and Comments:
Product Description:
This bestselling book is now the standard guide to building phone systems with Asterisk, the open source IP PBX that has traditional telephony providers running scared! Revised for the 1.4 release of the software, the new edition of Asterisk: The Future of Telephony reveals how you can save money on equipment and support, and finally be in control of your telephone system. If you've worked with telephony in the past, you're familiar with the problem: expensive and inflexible systems that are tuned to the vendor's needs, not yours. Asterisk isn't just a candle in the darkness, it's a whole fireworks show. Because Asterisk is so powerful, configuring it can seem tricky and difficult. This book steps you through the process of installing, configuring, and integrating Asterisk with your existing phone system. You'll learn how to write dialplans, set up applications including speech synthesis and voice recognition, how to script Asterisk, and much more -- everything you need to design a simple but complete system with little or no Asterisk experience, and no more than rudimentary telecommunications knowledge. The book includes: A new chapter on managing/administering your Asterisk system A new chapter on using Asterisk with databases Coverage of features in Asterisk 1.4 A new appendix on dialplan functions A simplified installation chapter New simplified SIP configuration, including examples for several popular SIP clients (soft phones and IP telephones) Revised chapters and appendicies reviewed and updated for the latest in features, applications, trends and best-practices Asterisk is revolutionizing the telecom industry, due in large part to the way it gets along with other networkapplications. While other PBXs are fighting their inevitable absorption into the network, Asterisk embraces it. If you need to take control of your telephony systems, move to Asterisk and see what the future of telecommunications looks like.

This asterisk title is not for the faint hearted, assuming you have a working knowledge of linux and not afraid to jump in to some command line configuration. That said, there is some great explanation for basic set up to advanced features and to hook up to various VoIP providers.
From my perspective I was hoping for more details such as configuring time conditions for holidays and things of that nature, so I felt the book stopped before it covered topics I wanted. For what it does to, it does it well with detailed examples and descriptions as to why things work they do.
Don't look for this title to be a novice walk through guide, but if you want some good reference for setting up your own small to large business installation having this book on hand is a good idea.

I'm enjoying the book and learning a lot from it, but this newest edition has some editing problems, such as typos:
Page 99: "providers may insteadSession Initiation Protocol" - and I don't know enough about the subject yet to figure out what they meant to say
and logical errors:
Page 71: "if you want to build an IP-only configuration, you can skip to the section on configuring SIP." - but if you do, expect to be coming back to this page because you'll have skipped over some important stuff and will have no idea what's going on
But these are comparatively minor problems with an otherwise great book.
