Hi everyone, I have a server which has multiple network cards configured with different IP addresses in different subnets. I would like to use only one IP address (internal) for the registration of phones. My problem is that I'm having difficulty to stop FreeSwitch from finding the external interface. It there somewhere a easy description of the process? Alternatively I'm happy to pay for some support, If someone would be so friendly to pass on a contact. It would be great if this person is in Australia, but I'm happy with anyone. Thank you for your help Dirk Eisner | Systems Architect Mine Site Technologies Pty Ltd.
