Very good reference for Asterisk

This book is a good attempt to hit the moving target that is Asterisk. I keep coming back to it and finding things to try and use. There is a lot of really good content and the Author does a good job of citing his sources too.
This book could do more for introducing the beginner to Asterisk - the concept of extensions in the dial plan is key to understanding Asterisk and it is a strange paradigm until you understand it. I wish this book had introduced it a little better.
Additionally, more dial plan and configuration file examples would have been a very helpful resource.
This book has been invaluable to me starting out with Asterisk. I would welcome updates and revisions as Asterisk expands.
