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?

... unless the handset you are using generates this kind of noise when it is not receiving incoming RTP.
