Even though there doesn't seem to be much activity on here I would post anyway and see what comes of it.

I have a VoIP number normally accessed by SIP directly from the Cisco 504G but now I have starlink at the farm it is viable to setup an extension there as well so I am setting up FreePBX at my home on a fixed IP. I have the IAX2 port forwarded on the router to the machine and have inbound calls working perfectly.

The issue I have is outbound call always come up with "All circuits are busy now" I have tried setting it up SIP and IAX2 both give the same result. If I put the phone back online and try it just works no problem so it is something in the setup of the IAX.

Config is as follows.
