Hi all,
When using STUN, I can detect my NAT type. The SDP contain x-NAT field (0: unknown, 1: full cone, ..., 6: symmetric) which tells Kamailio the NAT type of clients. Why doesn't Kamailio use that ?

then what would be this bad DSP or RTP packages dropping reason for that makes such noises? (for example if I speak louder that train soud gets louder or when I speak low the win/train sound gets lower as well)

I understand, but some times 2 UAs have audio one side voice is clear but in other side voice is just like train sound (or wind sound) is this from NAT too?
No. NAT does not introduce any acoustic anomalies; it would simply prevent the reachability of audio altogether. What you describe sounds like a bad DSP or gateway similar.
... unless the handset you are using generates this kind of noise when it is not receiving incoming RTP.
