Invoked by the JS SetLocalDescription must be called after CreateAnswer and takes as input the answer SDP which is passed down to the GSMTask thread.  Here the SDP is compared to the insernal answer SDP, if there is a difference an error is reported back to the DOM Thread.  If there are no errors then the webrtc.org streams can be created along with the mtransport flows. Following this if ICE completes processing successfuly then the media can start sending and receiving.

Following this if ICE completes processing successfuly then the media can start sending and receiving on the webrtc.org flows that were created in CreateAnswer.
 
[Question: Enda.  I am not sure what the interaction looks like for creating the webrtc.org flows and the mtransport flows.]
