By: Anthony Minessale II, Giovanni Maruzzelli

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.

FreeSWITCH XML IVR is basically a complex parameterized skeleton that takes a lot of arguments, and an arbitrary number of voice menu items, to create a complete application you can execute from a single dialplan extension.

Each voice menu item will react to DTMFs dialed by the caller, and will typically execute a dialplan application (bridge, transfer, playback, and so on).

XML IVR allows for timeouts, multi-digit input, text-to-speech integration, max wrong input acceptable attempts, submenus, back to main menu, menu repeat,...
