I have this symptom on some phones.
When a button is pressed, for example the settings button, the phone does nothing. Also when I try to dial a number. After a few seconds the pressed buttons are executed delayed. After a reset of the phone, the problem is gone for a while.
We are using CUCM 9.1.2.10000-28 and the firmware sip8961.9-3-4-24
