The voice mail operating mode may not be set correctly.

Mode 1 is the day greeting alll the time
Mode 2 is the night greeting all the time
Mode 3 is the clock-greeting follows the open and close schedule. If open and close schedule is not set correctly you may get the stock greeting instead of the one you recorded.
And the day/night mode of the phone system has no effect on the day/night mode of the voice mail.

Of course this depends on which greeting you choose to play when you set the Auto attendant config. I am assuming day is 1 night is 2
