On some phones, (typically D50 and D40 models) the following error started to happen:
When pressing the MSGS button, user will see the list of voice mail messages.
But trying to listen to them will not work.
It will return error codes like 500:10000 or 10001
Completely reverting to factory default then reconfiguring the phone will not fix the problem.
