Disclaimer: I received a copy of Tanner’s book for free and thought I would give a quick review on it.
I started reading through the book while we are looking at alternatives for our current voip systems here at work. I though the book was a really good read. The book is concise, and to the point. Which is something I can appreciate when I am just looking for instructions to add “custom media files for Music On Hold” for example. Keep in mind the book is written to be a quick reference for common problems, and implementations. You aren’t going to find hundreds of pages of telephony background of theory. Which for me is a good thing…
