How are the ports determined now so as not to conflict with one another?
If everyone set their server up to use a manually specified range of
ports it's likely everyone would choose something like audio:'50000'
video:'50002' or whatever and then everyone's in the same conference -
am I wrong about that?
Of course, if bridging then it's not a problem, but globally for
multicast it could be.
