Details

I am seeing repeated audio dropouts/disconnects on WebEx, along with WebEx trying to make a new PeerConnection. The result is a lot of PCs and bad quality.
This works on Chrome.
Pulling in people I have talked to privately. Potential theory: maybe WebEx is reacting badly to our early consent checking failure notices. Nils, is there some way to disable these?
We do use four peer-Connections for audio to avoid server mixing and have the local client mixing. We are trouble-shooting the issue with the drop and re-connection. It is unlikely due to the number of peer Connections since we have used for years back when WebRTC have not supported media multiplexing. I will give the detail on the private chat.
No there is no way to disable the consent checks. But looking at about:webrtc I see: STUN-CLIENT(consent): Received response; processing ... Consent refreshed So it appear not to be a Consent problem. I contacted Cisco about this and I'm waiting for someone form the WebEx team to get back to me on this.
Marking this P1 based on the worst-case of what we know so far. Please update accordingly if we find out more.

After chatting with duanpei the most plausible explanation for the dis-connects appears to a WebEx server side monitoring of the PeerConnections misjudging something and closing PeerConnection preemptively. It's pretty unlikely that this a regression in Firefox. The high amount of PeerConnections appears to be expected.

WebEx has made a change on their server side, which should fix/improve this.
For about the past month on Nightly, I've been losing audio connections on Webex as well, about 10 minutes in. Video stays up, and Webex prompts me to reconnect audio, however I hear nothing both ways when doing so unless I refresh the tab. (chromium works fine)
I am seeing this again
:mt reported the same problem today in #media.
We recently fixed a bug similar to what is described here. Could you please provide the WebEx Web App's version number? Just click on the upper left corner question mark sign and then "About". Also, if you could give me the meeting URL and meeting number, that will be very helpful. Thanks!
I can confirm this is gone with Webex Version 3.2.0.283.
