Review title: Best H.323 book on the market
Product review: This is by far the most comprehensive book on the market. I agree with the previous review, IP Telephony with H.323 is for advanced uses and a great reference guide as well. I highly recommend it if you want a thorough understand H.323 and IP Telephony, however, if you wish to learn about a particular subject, for example QoS or MPLS, this book will not provide enough detailed information (check out Cisco Press).Must buy!
