Webrtc client panel no buttons. The extension is not registered. And the phone goes out without dialer.
I have installed and configured FOP2 in Isabel with it as an addon and then I have followed this guide to use the WebRTC phone plugin. https://www.fop2.com/docs/webrtc_guide.php
In a clean Issabel it has worked for me 
but I have tried to import the configuration of a backup to migrate extensions, routes, etc. and the same thing has happened again. 
This is a capture:
