Hi, We are using odoo 15 on premise . 

In discuss module.. we cant start voice or video calls, it shows require permission.. Camera and microphone setting on my system have full permission. And when I try calls using other applications like Zoom or Microsoft teams everything is working fine.

• How can we resolve this?
• Some one told that this will be an issue with SSL certificate . If that's the issue then how can I create a SSL certificate and install it on Odoo hosted on ubuntu.
