Disorganized, a lot of typos

This is a book where you can see niether the author or the publisher paid much attention to detail, there are a lot of errors.

It does help on understanding a little about Asterisk if you are an absolute beginner, but if you managed to install an Asterisk server based on the information already avaliable in the wikipedia at voip-info.org then you dont need this book.

The good thing: this is the first effort to document Asterisk for the public, there is no other good book to compare it at this moment, I hope the second edition corrects all the errors.
