1. 1/5

   I have read many books in my day, of various categories, but this book is by far the worst I have ever read. VoLTE is a tricky subject, draws from many standards which are not easy to read. The purpose of the book should/must be to clarify and make sense of a complex subject matter. Instead the authour, clearly without any 'feeling' for what is important and critical, rambles on and repeats, much less pedagogically even than the standards, what the specifications say. Do not buy this book. It does not even deserve the minimum 1 star.
