Good information
I bought this book for one of my college class. It has great information and all up to date. The reason I didn't give it 5 stars is because it doesn't have page numbers in the book, so it was a little difficult when the instructor was calling out page number.

Three Stars
The material in the book is rather inconsistent and irrelevant to the study guide.

Worth buying it !!!!
It covers all the IP Voice for Cisco technologies. It is good to read for future CCVP or IP Telephony experts.I believe that this book combined with the IPT1 & IPT2 are the MUST READ books for VOIP and IP Telephony

bad
Not a good book at all for starter's. I am basically interseted in routing switching and wanted to learn about voip. But this book didnt help to arouse any interest in voice.
