I’m having a baffling issue. Running FreePBX 15. I do not have the extension route or CoS modules installed.
Without having made any changes, one of my extension stopped being able to make calls to outside numbers. I get “All circuits are busy”. Nothing shows on the console.
Where it gets really weird, is that if I take a functioning phone, plug it to that specific network location, it stops being able to make outbound calls. Move it to a new network drop and it still can’t make calls.
It is almost like that extension gets banned from using the trunk.
Factory resetting the phone does not help.
