How to set up wss on FreePBX?

Question

Asterisk

Good day.
Can't figure out how to get FreePBX to work with https://www.doubango.org/sipml5/ .
Created 2 extensions, through zoiper they connect and call.
Through the demo, registration goes through, but when you try to call, the server sends 488 not acceptable here.
And I can't find documentation on setting up via (freepbx gui).

For your extensions, you need to enable DTLS:
As far as I remember, this can also be done from the GUI in the process of creating / modifying an extension.
And, of course, you will first have to generate a certificate. I'm not sure if this can be done from the GUI, but the process is quite simple - and the guides are enough ( example ).
