Product Description
Asterisk is the world’s leading open-source PBX, telephony engine, and telephony applications toolkit with immense flexibility.

This book will give you a firm understanding of Asterisk Gateway Interface (AGI) development and proper AGI development practices. You will learn how to formulate Atomic AGI-enabled scripts, enabling rapid development within a well-defined Asterisk execution and runtime environment.

This book builds from the simplest form of an Asterisk application, the dialplan-based application, gradually building a full understanding of AGI scripting. The book also introduces a new concept of AGI development named “Atomic AGI” or “Particle Programming”. It will introduce you to various techniques of interacting with the user, where user interaction isn’t limited to keypad-based input, but also includes recording messages from the user, sending output to the user, and controlling the call flow.

The book takes a pragmatic approach with clear and complete examples, and a service development project — allowing you to understand the project cycle of developing an Asterisk-based service or application.

Approach

This friendly, clear tutorial takes a pragmatic approach to developing Asterisk applications, helping you to find the best solutions for your needs. Unlike most books, which simply show you how to do or what to do, this book tries to show you: “why to do?”–thus explaining the logic behind certain Asterisk development paradigms.

From the Publisher
Who this book is written for?
