SetRemoteRTPEndPoint() public method

Allows an arbitrary block of bytes to be sent on the RTP channel. This is mainly used for the Gingle client which needs to send a STUN binding request to the Google Voice gateway. Sets the remote end point for the RTP channel. This will be set from the SDP packet received from the remote end of the VoIP call.
public SetRemoteRTPEndPoint ( IPEndPoint remoteEndPoint ) : void
remoteEndPoint System.Net.IPEndPoint The remote end point to send RTP to.
return void
