I second Jeremy's comment- but will shim in a few caveats. chan_h323, which I personally love, support, and use daily in production and test environments, absolutely does work with CCM from at least 3.3.3 on through 4.0.1 (and I hear that 4.1 works too, but I haven't personally seen that one). HOWEVER- I strongly recommend using the latest versions of Asterisk, chan_h323, and CCM- and I have one really ugly hack in my Asterisk code which I haven't submitted because it is definitely a CCM issue (essentially, 729 and 729a negotiation isn't handled properly between the two, causing 729 to be selected in one direction, and 729a to be selected in the other- while supposedly equivalent, CCM doesn't like it and provides one-way audio as a result. My hack chops 729a out of the h323 channel driver entirely, forcing it to say it's 729 in both directions) Over the two years I've used chan_h323 to get to CCM, I've put in quite a few debugging hours- and it took until the 1.2 release before I was entirely happy with it. CCM doesn't seem to have as many version-related changes, but it's definitely quirky. And I strongly recommend use of a stable gatekeeper- some versions of gnuGK don't hold up to stress well in this type of use.
I'm happy to discuss how I'm doing it, and work with you to get a stable configuration.
