We are using rtcp mux where it uses the same port. This is the default for webrtc and I don't think we have a way to disable it for outbound invites for webrtc media, but there shouldn't ever be a reason to disable it as all the browsers support it and its required by the spec. As for why its not working with chrome for android, I'm not sure, do you have a debug log of the call?<br>
