This is the code repository for FreeSWITCH 1.8, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.
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.
All of the code is organized into folders. Each folder starts with a number followed by the application name. For example, Chapter02.
Chapters 01,03,04,07,13,14, and 15 does not have any code files.
The code will look like the following:
<extension name="get voicemail">
<condition field="destination_number" expression="^\*98$">
<action application="answer"/>
<action application="voicemail"
data="check auth default${domain_name}"/>
</condition>
</extension>
At the very least you will need a computer on which you can run FreeSWITCH. Typically this is a server although that isn't an absolute requirement. You will also need at least a couple SIP devices, be them softphones or desk phones, and a couple browsers as WebRTC clients.
