I have tried force-relay but I belive that only works when the clients already have ICE relay candidates, in that case rtpengine simply replaces them with its own.
are you sure that nothing is added if there is no existing relay candidates?
I can't believe there's no option to just add itself as a low priority relay candidate instead of messing with the hosts candidates as it seems to do by default.
force-relay is not messing with any other candidates than relay candidates.
