Ebook

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. It is always exciting to design and build your own telephony system to suit your needs, but the task is time consuming and involves a lot of technical skills.This book comes to your rescue, helping you to set up a telephony system fast and easily using FreeSWITCH. It will take you from being a novice to creating a fully-functional telephony system of your own. It is rich with practical examples and will give you all of the information and skills needed to implement your own PBX system.The book begins by introducing the architecture and working of FreeSWITCH before detailing how to plan a telephone system and moving on to the installation, configuration, and management of a feature-packed PBX. You will learn about maintaining a user directory, XML dial plan and advanced dial plan concepts, call routing, and the extremely powerful Event Socket. You will finally learn about the online community and history of FreeSWITCH.
