T21P Low headset volume
Hi,

I have bought 50 T21P phones

Firmware Version: 34.72.0.75
Hardware Version: 34.1.0.0.0.0.0

All of them have a headset volume level problem. The audio is too low.
I found all this threads with similar problems.

No solution at all.

I'm hoping that some of the forum have solved.
