If this is a PIX, and not using same level security interface, then one side is going to be higher security than the other. If no fixup exists for H323 then the dynamic RTP traffic will not be accounted for.
Here is a sample document explaining fixups for voice.
Also if you could post your settings for both side of the Trunks. Depending on if you are using H323 slow start or fast start, the signaling ports changes. Slow start uses a dynamic range I believe so you want to make sure the trunks are not using it. This of course will affect your fixups.
These are the paths to get to each CCX logs through CLI. They may be helpful if you are having issues accessing RTMT or downloading logs through it.
If you want to download them you have to prefix "file get " and you can add one of the options (re...
