Freeswitch Voip Book for version 1.0.6
I just got a copy of the recently released FreeSwitch 1.0.6 book, which you can look at here https://www.packtpub.com/freeswitch-1-0-6-build-robust-high-performance-telephony-systems/book. I quickly browsed through it and it looks very informative with many examples and explanations. This book has a lot of information that is not available on the internet so it is worth picking up. If you would like to look at a sample of the book this link offers you chapter 4 of the book. https://www.packtpub.com/sites/default/files/9966-chapter-4-sip-and-the-user-directory%20.pdf
After I finish reading the whole book I will post a full review.
