As I figured, every time I reload freepbx, the configuration file changes.
My main extension, let's call it 402 is setup as:
nat=force_rport,comedia
no matter what, even if I recreate the bria extensions, 999402 is always:
nat=no
So there's no way to edit the extension manually, and the bria cloud services module isn't creating the user correctly.
Bria cloud solutions module is up to date (12.0.11). User Management is 12.0.27.
Is this a bug?
