[asterisk-users] Forbidden - wrong password on authentication for INVITE

[Giorgio Incantalupo]

Hi,
I'm using messagenet VoIP provider, I can make calls but I cannot 
receive calls.
When I call my VoIP number the phone rings but when I pick up the call 
drops and I get this message on Asterisk console:
*Forbidden - wrong password on authentication for INVITE to ...*

Is there anybody who knows why?
