Hello, in the standard setup - if a phone is registering to port 5060 - it is bound to the "internal" profile. And I can dial it via sofia/user/xxxx then. However due to NAT issues I would like to have to 2 seperate profiles for SIP phones. For example I have a "local" profile for all devices inside the LAN (e.g. Pattons und in future: local phones) and another "internal" profile which allows also external phones via external-xxx-ip. That way I would like to ensure that local phones have nothing to do with natted adresses and that external phones can register via external IPs. Question How do I manage that I can register a phone to the "local" profile and being able to dial that phone via sofia/user/xxxxx? Or do I think too complicated and there is simply nothing special to do? Best regards Peter
