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…
I thought Cisco would wait until Cisco Live to do the announcement, but looks like they wanted to give everyone time to come up with some questions. I am curious if any of the hardware changes are going to slow down any of the training vendors in updating their material? The additional hardware seems to remove any option of a home lab unless you are just burning piles of money in your spare time already The additions of the wireless controller, and IP phone is interesting.
This is what I have been honestly waiting for to see if taking the 3.0 written exam is worth it, or to just wait for the 4.0 version to go live.
