Subject: [Freeswitch-users] FreeSWITCH Book Has Arrived!

We are very pleased - and relieved - to announce that the FreeSWITCH book has officially been released! You may purchase it online here:

https://www.packtpub.com/freeswitch-1-0-6-build-robust-high-performance-telephony-systems/book

There is an eBook special price of US$4.80 - take advantage of this price because we do not know how long it will be available.

Tony, Darren, and I would like to thank everyone who proofread the text, offered feedback, and generally gave us encouragement when things got tough. Writing a book is quite an experience and we are better off for the experience. We learned a lot, to be sure, and we rediscovered what a supportive and enthusiastic community we have with FreeSWITCH.

We appreciate your continued support of open source projects like FreeSWITCH and the open source telephony developer conference, ClueCon. Keep up the great work!
