I'm trying to connect to a local PBX using SIP on a secondary line using a VVX 410, however the first line is already connected to a remote system that requires the NAT settings to be enabled. This is causing the endpoint to resiter on the local PBX using the public IP address, making it unreachable.
How can I disable NAT settings for one specific registration so the endpoint is registered with it's LAN address? Alternately, if I disable the global NAT setting, is there a way to re-enable it for a specific line?
Cheers,
JE
