There an introduction to H.323 at http://www.voip-calculator.com/h323primer.html. It may not be in enough detail for you though.
The H.323 protocols cannot easily be read and decoded. The information is not always byte aligned. It is encoded using PER (Packet Encoding Rules – X.691).
This makes it very compact, but very complicated.
