I guess this review on Amazon sums it up.. Good text -- but missing important features, September 20, 2005 By Mark R. Lindsey (Valdosta, GA, USA) - See all my reviews (REAL NAME) This is a well-written text; it compiles a lot of good information on important issues. I enjoy reading it, because there is a lot of info on things I don't understand. For example, it has an introductory description of how faxing works, then touches on how T.38 works with that approach. There's also some information on what you'll usually see in equipment, and about movements afoot that aren't quite widespread as yet -- e.g., ENUM lookups for routing calls. The author sprinkles in his opinions and technical/aesthetic tastes, however. While it's very informative, some sections read like opinion from a magazine like MacWorld. For example, the authors praise H.323 for its greatness, but criticize SIP for being as a bunch of vendor hacks. But it's missing some key features -- like a useful index (it has one of those sparse six-page indexes for a 380-page book), or even a bibliography! The lack of a bibliography is particularly offensive. For example, the authors claim that "95% of VoIP minutes worldwide" are controlled with H.323, but provides no basis for that claim.

"IP Telephony" by Hersent, &al., covers H.323 in some depth. He also covers SIP and MGCP. http://books.google.com/books?id=gC0U-nDGvvsC
Hersent seems to be an H.323 elitist. I get the feeling he really wants to say, "You SIP users are silly children, with your skulls of IETF mush, as if you can re-invent telephony! I spit on your silly extensibility and lack of respect for the great and wise ITU-T fathers."
Despite that, it's quite a useful book.
