registrar which seems picky about that. The error message is:
SIP/2.0 479 Please don't use private IP addresses
This is a known issue with some registrars.
I had this also with another voip software under Linux and I hoped that
Linphone behaves differently in such a scenario.
Does this sound familiar, did anyone experience the same?
Linphone (at least version 3.1.2) has the possibility to specify the
public IP address of a gateway. Look at the 'Network settings' tab
under 'Linphone -> Preferences'.
