Implementing sofia_contact on bridge function I discovered one thing that 
could help debugging described in the previous message.
If i try to call the extension few seconds after the registration  
sofia_contact returns "sofia/internal/sip:900 at X.X.X.X:PORT", with X.X.X.X 
public ip address of the phone, but after some minutes sofia_contact returns 
"sofia/internal/sip:900 at Y.Y.Y.Y:PORT" with Y.Y.Y.Y local ip of the phone.
I don't undestand if is a FS problem or client problem: I detected this 
problem with a snom 300 and a thomson ST2030, but I didn't detected the 
problem with x-lite softphone and siemens gigaset a510IP.

still thanks in andvise :)
