CUCM System version: 18.104.22.16800-18
Phones 8811 firmware sip88xx.12-7-1-0001-393
Users in two different buildings are reporting their phones are beeping and flashing a message on the phone display telling them they are being too loud. Initially I thought they were talking about paging and that someone was playing jokes. But the message displays on the phone screen, the only sound is a beeping tone.
You can definitely disable it via the phone settings, but only Via the device menu and not centrally via the CUCM.
Is there a way to turn that off in Call Manager or does it have to be done from the phone?

NOTE: This is a "feature request".
This is "Lower your Voice" Notification and it was introduced on firmware 12.7. This is a feature that could be disabled.
3rd party apps like Variphy (probably others) can run macro's to replicate the button presses necessary to disable this feature at a device level. You can run it against device types, devices pools...it can also be scheduled to run off hours.
This is what I just finished doing for about 2,500 phones.
