This is the third book in a Trilogy: FreeSWITCH 1.6 Cookbook, Mastering FreeSWITCH, and yours truly, FreeSWITCH 1.8. Each one of them has its own role in FreeSWITCH's Universe. The call of this one you're reading is to be the reference and foundation, the exhaustive source of FreeSWITCH knowledge.

We've worked hard, we started from the efforts of our co-writers in FreeSWITCH 1.2 book (they were Michael S. Collins, Darren Schreiber and Raymond Chandler), we've updated, rewritten and written anew and we're now proud to introduce you to all you need to know about latest FreeSWITCH.

So much happened in the world of Real Time Communication and VoIP in the last years. And FreeSWITCH was leading innovation, implementation and interoperability in the industry: WebRTC, Video MCU, High Definition Audio, OPUS, VP8/9, JSON, Encryption and Security, you name it, FreeSWITCH was there.

We're about to announce FreeSWITCH 1.8: an evolutionary step from 1.6, that enhance performances and changes a lot of under the hood plumbing that will be the nervous system of  The Next Big Things (TM) in FreeSWITCH Universe.

From an operation, administration and application programming point of view 1.8 is completely compatible with 1.6, and this book cover them both.
