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

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.
