Hi Benny, Thanks for your clarification for TURN usage.We here are of opinion that UDP based media can be sent through symmetric NATs(in case where one end point or both are behind symmetric NATs),only by using TURN.Is our opinion appropriate? Waiting for your answer.We have to taken some major decisions based upon your reply.
