asterisk users - Apr 2004 - i'm looking for reference guide for Skinny SCCP

Hi all,
I'm writing my graduation theses : analysis VO-IP protocols , and I cannot 
find any documents about Cisko Skinny Client Control Protocol. I have Cisco 
CallManager and some IP-phone and I'm sniffing traffic between that, but I 
don't understand, how this protocol works. Clearly i'm looking for 
description of SCCP commands and explanation some basic SCCP scenarios or 
what including SCCP packets ...
I have a lot of alredy information about SIP,H323 and others, but about SCCP 
nothing:-(

Thanks

Cisco does not document the SCCP protocol.  There are no public docs
available for this protocol.  The Asterisk SCCP/Skinny support was done
by using a packet sniffer.

SCCP is not a public protocol.   Lets consider ourselves lucky that 
Cisco is not actively protecting what little documentation is out there.
