Product Description
An easy introduction to using and configuring Asterisk to build feature-rich telephony systems for small and medium businesses. Install, configure, deploy, secure, and maintain AsteriskBuild a fully-featured telephony system and create a dial plan that suits your needsLearn from example configurations for different requirements In Detail Asterisk is a powerful and flexible open source framework for building feature-rich telephony systems. As a Private Branch Exchange (PBX) which connects one or more telephones, and usually connects to one or more telephone lines, Asterisk offers very advanced features, including station-to-station calls, line trunking, call distribution, call detail rerecords, and call recording. Asterisk can be used to provide Interactive Voice Response (IVR). The power and flexibility of a programmable phone system gives us the ability to respond to our customers in meaningful ways. Asterisk has also a fully-functional voicemail system included. It supports voicemail contexts so that multiple organizations can be hosted from the same server. It supports different time zones so that users can track when their phone calls come in. It even provides the option to notify the recipient of new messages via email. In fact, we can even attach the message in audio! Finally, Asterisk is a Voice Over IP (VoIP) system. The benefits of VoIP are numerous. For instance, we can have multiple users using the same Asterisk service from a variety of locations; we can have users in the local office using PSTN phones or IP phones; we can have remote VoIP users; we can even have entire Asterisk systems operated and run completely separately but with integrated routing; We can have an extension anywhere we have a reasonably fast Internet connection, which means employees can have an extension on the phone system at home if they have a broadband connection. The benefits are too many to list. Flexibility often means complexity, and this is true in the case of Asterisk. This book is all you need to understand and use Asterisk to build the telephony system that meets your need. You will learn how to use the many features that Asterisk provides you with. What you will learn from this book? This book takes you from installing and configuring Asterisk to using its various advanced features�, helping you build feature-rich telephony systems. With this book, you will learn how to:Install, configure, and deploy AsteriskCreate a dialplan that suits your needsBuild a fully-featured telephony system Monitor, record, and log calls Install and use Asterisk@HomeBackup, secure, and maintain AsteriskUse example configurations for different requirements Approach Who this book is written for? This book is aimed at anyone who is interested in building a powerful telephony system using the free and open source application, Asterisk, without spending many thousands of dollars buying a commercial and often less flexible system. This book is suitable for the novice and those new to Asterisk and telephony. Telephony or Linux experience will be helpful, but not required. |

Slightly outdated, but straight to the point by T. Miller (Atlanta, GA USA)  4 Stars
April 29, 2008
While this book is "old" in terms of when it was first published for the computing world, but it is straight to the point. I bought it to investigate what I would need to do in order to setup a PBX for my small business. It's actually so straight to the point that I wasn't able to do much beyond the first couple of chapters because it pretty much requires you to have a machine that you can install software on and use to test and experiment with -- which I don't have yet. So if you're committed to getting going on an Asterisk PBX, this book would probably serve as a good resource to you.

Telephony Systems with Asterisk by David H. Moon (Pocatello, Idaho USA)  3 Stars
August 02, 2007
I was hoping that this book would be more specific. I needed better real world examples of how to build a workable dial plan. While there were numerous examples, this book fell painfully short in teaching the theory of context location. An example is on page 77 where the author states
"We simply place each handset into one of two contexts, based upon what number we want them to be able to dial." Which configuration files contain the contexts that we need to place the extensions into? There are other similar examples. What this author should have done is detail every configuration file involved showing exactly what was happening and where. Now, I understand there are more that one flavor of dial plan. However, statements as shown above aren't even close to what is expected of a subject matter expert. I give it a 3 because it is of help to beginners but it won't get the job done standing alone..

Good Reference by C. Bullock (MS, USA) 4 Stars
January 11, 2007
I found this book very helpful. Sometimes it felt a little disorganized, but it did help me get off the ground with Asterisk. The free book from O'Reilly is also a great reference. All that being said, I would still purchase this book if I had it to do over.

Too simplistic by Yakout Yakout 3 Stars
December 03, 2006
This is a good book for ASterisk/VoIP beginners only. I was expecting much more than this. It was written in a very simplistic way, which is good for beginners no question. It doens't provide any form of Troubleshooting, even for the most common known problems (example: NAT)

It's good for what it is. by Ryan Egesdahl (Hempstead, TX USA) 3 Stars
November 18, 2006
Don't go about thinking this is a book for someone who wants to know what Asterisk is all about. The book is very specific to business applications and it does not treat more than a few configurations and case studies. It's very understandable, but it's not a book to read if you want to understand PBX design.
