I have a D725 with one D7 expansion module and a Snom blue tooth adapter running 126.96.36.199. If the phone reboots the D7 will power up but it will not work. None of the buttons display on the D7. The screen is on but there is nothing in the display. The only fix I have found is removing the blue tooth adapter, rebooting the phone and inserting the blue toot adapter.
Hi Alan. I have sent you a firmware via email. Could you test and let me know how it works with this one?
