[OpenSIPS-Users] Registrations from different ports?

[Bogdan-Andrei Iancu]

Hi David,

OpenSIPS does not support sip.instance (yet).

A simple solution to your case will be to configure opensips to accept 
only one contact per AOR and to overwrite any existing contact when a 
new one is uploaded. See the 'f' and 'cnn'  flags for the save() function.

Regards,
Bogdan
