Well, asterisk also supports H323. So why don't you just define H323 trunk 
between asterisk and CCM and create some routings so CCM calls directly to 
astering and vice-versa?

Or perhaps you have tried it and failed? Make sure you have recent asterisk 
and oh323 H323 stack, asterisk 0.6 or so and it's native H323 stack were 
broken when I last did this kind of interconnection. More recent ones work 
well.
