Hi there,
Well it's mostly rtpengine question but didn't know where should I send 
it and probably the answer will be more or less useful for kamailio users.

By default if an offer has ICE candidates rtpengine leaves them 
untouched and just inserts itself as an additional low priority 
candidate and also rewrites c= line for the callee without ICE support. 
Using ICE=force-relay rtpengine inserts itself as a "relay" candidate 
what is great but doesn't touch c= line and callee without ICE have no 
chance to send RTP to rtpengine.
Is it possible somehow to make a third behavior like force-relay + 
rtpengine IP in c= param? It would allow any callee to send media to 
rtpengine regardless of ICE support.
