I'm guessing MTP gets allocated here due to DMTF mismatch and your conference ends up as audio only.

To confirm check MTP usage in RTMT or collect CUCM traces and search for a line similar to the below:

00123297.009 |09:10:20.345 |AppInfo  |DET-MediaManager-(58)::isMTPNeededForMismatchOrConfig, MTPNeededDueToDTMFCapMismatch(2833/OOB) mtpinsertionReason=1 dtmfMTPSide=1
