Default handset, headset & speaker buttons for 9620 don't work

I have found case ID 15427605
Status: Closed
Abstract: Unable to hang up with handset, headset and speaker button for 9620 phones for serial number in 07N52071XXXX series ( Consultation QQ)

We have the same issue, but with serial numbers 12N...
What can we do? Firmware 3.105S & 3.103 with the same result.
Or the only way is to change phones? Can other phones 12N... go to the same state?
