Rtpengine works by rewriting the SDP bodies carried within SIP messages, 
and these would also include all ICE details if ICE is supported (by the 
endpoints) and enabled. It also learns new ICE candidates during the ICE 
handshake (through STUN packets) as required by the RFC, but again this 
only happens if ICE is supported and enabled.
