Hey Richard,

So it is true rtpengine is handling rtp between kamailio and receiver
(freeswitch).  I'm trying to understand if there is a way to not
forward rtp to any of the ICE candidates in the original INVITE request
from the client side.  In other words, have the client rtp forward directly
to the rtpengine and not any of the STUN servers (or ICE candidates).  i
honestly thought putting ICE=force in the rtpengine_answer would help in
this case...but I don't see this part working.
