Asterisk config apply problem

I tried asterisk11 with luci-app-asterisk. I saved some settings on gui, but none of them copied into /etc/asterisk/ config files, all of them remain unchanged. How can i apply settings changed on gui to the real config files?

Asterisk 11 reached EOL last year, so I don't recommend using that. luci-app-asterisk seems to be unmaintained, so currently the only solution is to edit the Asterisk configuration files manually.
I'm currently trying to update the Asterisk documentation, so you might have a look here: RFC on new Asterisk wiki page.
I highly appreciate feedback on how to improve the docs.
