Hi there,
I just made a strange observation. If I dial in with my phone via Jigasi into a conference room, I cannot hear the phone user speaking, when I’m using Firefox. If I’m joining the conference via chromium everything works completely fine and I can hear the phone user speaking. I first thought this was only a codec issue with my self hosted jigasi configuration or voximplant, but the issue was also reproducible on meet.jit.si
I tried this with Firefox 79.
