I've checked the code in Meetme and confirmed that feature should be
working as expected. I would suggest you do some additional testing to
confirm it isn't.

Asterisk doesn't allow you to manipulate the SDP as such so I'm afraid
there is no way for you to change that value. Internally within
applications they just discard the media received under such circumstances.
