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


FreeSWITCH is a complex system of moving parts that are integrated to produce a solid, stable core with flexible and easy-to-extend add-ons. The core extends its interfaces to modules. The modules also can bring outside functionalities into FreeSWITCH by translating various communication protocols into a common, abstract, internal format. We looked at the various module types, and demonstrated how they revolve around the core and interact with each other to turn simple abstract concepts into higher-level functionalities. We described a few of the more popular applications in FreeSWITCH-the conferencing and voicemail modules and how they, in turn, make use of other modules without ever knowing it. This agnosticism is accomplished by means of the event system. We also saw how the demonstration configuration provides several working examples to help take the edge off of an otherwise frightening feat of staring down the business end of a full-featured soft-switch.

In the following chapter, we will take our first steps towards getting a FreeSWITCH system up and running.
