Sorry for the phrasing, yes I meant in case of symmetric NAT would mediaproxy solve the natting problem.
I got the main idea, thanks a lot for your help

Thx

What does mean "STUN did not help a NAT client"?
STUN doesn't work behind a NAT symetric router. In any other NAT type router 
it works.
Anyway, the clients performs a NAT test and if they discover that they are 
behind a symmetric NAT router they warn the user about they cannot use STUN.

Rtp/MediaProxy are solutions that force the audio going through a server with 
public IP. Also nathelper module makes fix the private IP's in the original 
message ("Contact", "Via"...).
