This may be brute force and there may be more elegant methods, but I
just monitor on the server with "tethereal -R rtp" and if I see packets
then * is not releasing the media stream.  The problem is that I have
found that this can impair call quality if you leave it up, so I only do
it to spot check.  Also, I do an ethereal trace on the UA and look at
the source/destination address of the rtp stream and that should tell
you as well if the rtp is released.
