Same problem here except Firefox crashes after the call connects, AppCrashView shows the crash to be related to ‘xul.dll’
Test call does the same thing, hangs up while you’re supposed to say the message. Recording, just in case it’s useful: https://phone.firertc.com/calls/5b8684697475633be2160000/recording (Note that I was speaking, and the waveform does not show up)
I used FireRTC for quite some time before this happened. Not sure when it started as it was during a period where I wasn’t using FireRTC at all. Other applications like Skype work, webrtc test is good (or at least I think so, can provide screenshot)
Edit - Just tried to call the test number again while recording the call, and using the soundboard. I could hear the soundboard, but it didn’t show up in the recording. The test service hung up at the same time as before.
