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.

Its first implementation is in web browsers (more than one billions WebRTC compatible browsers out there), its technology is already in use by many of smartphones' apps, and is predicated to be the base for Internet of Things (IoT) multimedia communication (will be many billions IoT devices WebRTC enabled).

In the most straightforward and popular implementation, the browser will access a website and load a page that contains Javascript. That script functions use WebRTC APIs (see below) to interact with the local computer multimedia hardware (microphone and camera) and to stream audio and video to/from peers.

The emphasis here is on peer-to-peer.WebRTC does not prescribes or support anything that goes beyond grabbing, sending, receiving, and playing streams. No signaling, no user directory...
