[VoiceOps] Any good book on H323?

[Mark Holloway]

I guess this review on Amazon sums it up..

Good text -- but missing important features, September 20, 2005

(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.
