I have a system running ~50 Digium D60/65 phones that are configured through EPM w/DPMA apps on Freepbx16. They are all ignoring volume settings when set through endpoint manager. The option to lock/unlock the ringer volume works, but the volume will stay on whatever the user had it set to before the lock, rather than the setting in the config. I have tried editing the basefile to set the volume, but this does not work either. The only other thread I have found regarding this issue was 2 years old with no resolution, that pointed out a bug in the 2_9_18 version of the firmware that could cause this, but all of these phones are running 2_9_25.
Has anyone else experienced this? If so, what was the resolution?
