This is not a consistent trouble. At times, a user will notice their MWI is on and upon checking messages, the voicemails are from the day prior. Yet the MWI did not light the day before. System time is corrrect and this is not specific to one user. Only 6 users with voicemail and call volumes normal. The control unit has been rebooted.
