WebRTC

Hi, I've installed fusionpbx on Debian 9 with 4.5.9 version. How can I enable WebRTC on it. I've installed valid SSL. When I click at option webrtc it takes me to "number" to dial, I dial but nothing happen. Even I do not see any log generated in sngrep and console. Please advise.

Hi Dario, Thanks for reply. SSL is working fine on the machine. When I logged in it says secure. When I see in registration I find registered on WSS but still I'm not able to call out. When I dial just video window pop up and nothing else happen. Even free-switch logs are silent.
