Ring Central Meetings uses an API that windows computers recognize as a phone, and it auto adjusts the volume down 80% whenever you get into a meeting.
To fix this, change this windows setting, and it won’t do it anymore!
1. Right click your volume icon in system tray and select Playback devices.
2. Select the Communications tab.
3. Change the radio button to "Do Nothing"
This should solve your issue with meetings lowering the volume :)
