But that is what's happening, isn't it? What other media would rtpengine 
be sending to the client if not the media received from the other 
client? So your A client is sending to rtpengine, and rtpengine is 
forwarding that to B, while your B client is also sending to rtpengine, 
which then forwards it to A. Where do you not see that working?
