Title: Not worth reading
Review: I am not new to VoIP, and I know it fairly well already (attend the standards bodies, etc.), but I needed to find a good book for other employees. This was not it. Uyless left many errors, many open topics, and frankly the book is not really about Voice over IP in detail. There are much better books out there: Olivier Hersent's "IP Telephony" and Duskalis's "IP Telephony" are much more thorough on VoIP (despite their titles), although they are somewhat out of date already. (anything over 6 months old will be)
