I couldn't capture packets directly in the server... Now i'm on another LAN (and i have acess to ngrep). Everything seems working well, the only problem is that when the clients are in the same LAN they shouldn't use mediaproxy and communicate directly instead. I capture some packets of this communication and i have my openser.cfg so that you can give a look.
Many thanks for your interest and your contributions !
Capture with ngrep:
interface: eth0 (193.136.82.0/255.255.255.0)
filter: (ip or ip6) and ( port 5060 or port 5190 or port 5192 or port 5194)
