T19 and T21 Ring Volume Control

We have telephones T19E and T21E.
We would like to know if it is possible to control the ringer volume at the administrator level, eliminating the control of the end users. That is, prevent that the user lower the volume or turn it off completely.

Reference: Yealink T19 E2
Firmware: 53.82.0.20

Thanks for the help you can give us

Hi,

Please provision the phone with next parameter and try again.

Code:

#Configure the ringer volume forced, so the user cannot adjust the ringer volume on the phone.
force.voice.ring_vol =

Hope this will help.
