Okay, so after having a spelunk through the source code, I have the impression that this MOS / quality analysis functionality is limited solely to feedback off RTCP supports.
I was under the impression from the documentation that RTPEngine does some stream analysis of its own, although in fairness, the documentation does not explicitly make this claim or the contrary one way or another. :-)
It does gather some stats about the media streams on its own (even more so with the extended transcoding capabilities now), but at least one component of the MOS calculation (latency) depends on RTCP being provided by the RTP clients, so without that, no MOS score can be produced.
