Possible that I'm being dumb here but trying to set up a trunk to the inside interface and IP of our SBC from thirdlane on the local network. Thirdlane tries to use it's outside/public address to connect when I make an outbound call. This obviously fails. The local interface of Thirdlane and inside of SBC are on the same network (192.168.20.x/24) and can see each other.

An inbound call ITSP - SBC - Thirdlane routes ok and rings through although we've one way audio. (possible this is part of the same problem)

Is it possible or how can I can get the trunk to use the inside/local interface to route to SBC?

Kind Regards,

Hello Scott!

You need to add "" to the Local Networks section next to the corresponding network interface on the Network Topology screen. Please see this link https://www.thirdlane.com/docs/platform/network-topology to find more information.
