- mortehu 4y agoWebex will by default listen for ultrasound emitted by some video conferencing devices for easy stop. If you disable this, does that change the results?
- viknod 4y agoI was suspecting this was webex, I use an external audio device (plantronics/polycom Calisto 7200) that has an indicator when the microphone is active. It's only anecdotal, but for me when the webex ultrasound features is activated, the microphone is constantly active as long as webex chat is running. When the ultrasound detection is disabled, the microphone is disabled when not in a meeting. As an aside, this setting was reset recently, but that just seems like the ongoing dark pattern/incompetence of "forgetting" privacy settings between software releases.
- Swannie 4y agoMy understanding is that it activates when you make the Webex Teams/Meeting the application with focus, and should turn off some time after it is no longer the active application, I think ~60 seconds. It is doing this for the ultrasonic room detection feature, which can be turned off.
