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 GatewayInterface (AGI) development and proper AGI development practices. Youwill learn how to formulate Atomic AGI-enabled scripts, enabling rapiddevelopment within a well-defined Asterisk execution and runtimeenvironment.
This book builds from the simplest form of an Asterisk application,the dialplan-based application, gradually building a full understandingof AGI scripting. The book also introduces a new concept of AGIdevelopment named “Atomic AGI” or “Particle Programming”. It willintroduce you to various techniques of interacting with the user, whereuser interaction isn’t limited to keypad-based input, but also includesrecording messages from the user, sending output to the user, andcontrolling the call flow.
The book takes a pragmatic approach with clear and completeexamples, and a service development project — allowing you tounderstand the project cycle of developing an Asterisk-based service orapplication.
Approach
This friendly, clear tutorial takes a pragmatic approach todeveloping Asterisk applications, helping you to find the bestsolutions for your needs. Unlike most books, which simply show you howto do or what to do, this book tries to show you: “why to do?”–thusexplaining the logic behind certain Asterisk development paradigms.
From the Publisher
Who this book is written for?
This book is intended for developers wishing to utilize Asterisk,system administrators wishing to gain better control over theirAsterisk installation, and telephony service providers wishing todeploy Asterisk-based solutions to their infrastructure. You areexpected to have some experience with Asterisk and a basicunderstanding of programming. No knowledge of Asterisk programming isrequired.
