1.7. This Book

So where to begin? Well, when it comes to Asterisk, there is far more to talk about than we can fit into one book. For now, we're not going to take you down all the roads that the ¼ber- geeks followwe're just going to give you the basics.

In Chapter 1, we cover some of the engineering considerations you should have in mind when designing a telecommunications system. You can skip much of this material if you want to get right to installing, but these are important concepts to understand, should you ever plan on putting an Asterisk system into production.

Chapter 2 covers obtaining, compiling, and installing Asterisk, and Chapter 3 deals with the initial configuration of Asterisk. Here we cover the important configuration files that must exist to define the channels and features available to your system. This will prepare you for Chapter 4, where we introduce the heart of Asterisk, the dialplan. Having covered dialplan basics, Chapter 5 introduces some more advanced dialplan concepts.

We will take a break from Asterisk in Chapter 6, and discuss some of the more important technologies in use in the PSTN. Naturally, following the discussion of legacy telephony, Chapter 7 discusses Voice over IP.

Chapter 8 introduces one of the more amazing components , the Asterisk Gateway Interface (AGI). Using Perl, PHP, and Python, we demonstrate how external programs can be used to add nearly limitless functionality to your PBX. In Chapter 9, we briefly cover what is, in fact, a rich and varied cornucopia of incredible features and functions, all of which are part of the Asterisk phenomenon . To conclude, Chapter 10 looks forward, predicting a future where open source telephony completely transforms an industry desperately in need of a revolution. You'll also find a wealth of reference information in the book's five appendixes.

This book can only lay down the basics, but from this foundation, you will be able to come to an understanding of the concept of Asteriskand from that, who knows what you will build?
