Overview of this book

FreeSWITCH is an open source telephony platform designed to facilitate the creation of voice and chat-driven products, scaling from a soft-phone to a PBX and even up to an enterprise-class soft-switch. This book introduces FreeSWITCH to IT professionals who want to build their own telephony system. This book starts with a brief introduction to the latest version of FreeSWITCH. We then move on to the fundamentals and the new features added in version 1.6, showing you how to set up a basic system so you can make and receive phone calls, make calls between extensions, and utilize basic PBX functionality. Once you have a basic system in place, we’ll show you how to add more and more functionalities to it. You’ll learn to deploy the features on the system using unique techniques and tips to make it work better. Also, there are changes in the security-related components, which will affect the content in the book, so we will make that intact with the latest version. There are new support libraries introduced, such as SQLite, OpenSS, and more, which will make FreeSWITCH more efficient and add more functions to it. We’ll cover these in the new edition to make it more appealing for you.

Preface

Summary


In this chapter we delved very deeply into the operation of the FreeSWITCH Dialplan. Building upon the foundation laid in Chapter 6, XML Dialplan, we discussed many advanced Dialplan concepts:

  • How Dialplan parsing works
  • Using global variables and channel variables
  • Advanced use of regular expressions
  • Various advanced routing concepts

The Dialplan system in FreeSWITCH is one of the most important concepts you can learn. The power of FreeSWITCH is truly unleashed within the Dialplan system itself, and understanding the complexities of using various functions within FreeSWITCH is key to ensure that the FreeSWITCH performs exactly the way you want.

In the next chapter, we will lay the foundation for doing very powerful FreeSWITCH configurations that do not rely solely on the static XML files.
