I have noticed that when I use symetric NAT the quality of sound & video is better then when I use other NAT types for initiating call. Is it because it is through the TURN server relay agent. In that case how can I find out that my audio & video data is going throuth TURN server or its p2p. How can is force PJSIP/PJSUA to use TURN relay agent instead of direct p2p connection.
