hi, iam trying to implement a openser MediaProxy under nat. I use USER1
with 10.0.0.x  and media proxy to resolve nat. User 2 have 192.168.0.x.
Both clients can register in openser (with mysql accounting), but when
i try do call each other, i get error CALL FAILED: Proxy Authentication
Required. Iam using xlite sofphone on my clients.
