Hello,
I can fix your webRTC issue.
May I know the Asterisk version? ... sometimes Asterisk needs to be upgraded to latest version to
make WebRTC working. I can also update Asterisk but if you are already using any updated version then it just need fixing.
I have more than 10 years of voip development experience.
