Reading the first few chapters and I thought this is great instruction in getting an Asterisk PBX up and running quickly and then the next chapters went into required detail information on why things are done the way they are. It could very well be used as a training document and likely become "The Asterisk Guide".

Although the first chapters are required reading for anyone using the Asterisk PBX, Chapters 10 though 15 are more aptly fitting the title of the book Future of Telephony with opinions on how things came to be and thoughts on how they might turn out over the years .

The numerous appendix is an invaluable resource of information for Asterisk Programmers, installers, and managers and I am sure it will have a deserving place on my desk.

I highly recommend the Asterisk The Future Of Telephony to anyone. A good read and very informative.
