can you create a trunk in CCM pointing to a router which is running CME? If so, then on the return side of that do you use just use normal destination pattern commands to point calls back towards the actual CCM?
Yes, you are right. This can be done, but I think if you do this then you would need a MTP for the calls. I've personally preferred to add CME as a H323 Gateway and not a trunk.
Check the following link (TAC CC Document) which gives you more information about how it works.
