9641g BM12 Button Module fading Display Issue
9641G phones, the display on the button module fades after some time intermittently. Rebooting of the phone resolves the issue but after some time issue appears again and we have to do another reboot to fix this.

Customer is running on a special fimrware 6.2.122. Problem can be duplicated, if we connect one or two BM12 Button Modules to an Avaya 9641g IP Phone. No changes have been made since then, this is a new Install.
