you mean just 1 key press had all the extensions reach the Main Office VM??
if so we do not have any functionality like that, if it's time based you can use TOD for that purpose, whenever they're out of shift they will reach the main office VM. other option would be to configure a night bell and when they go home have them press CFA + night bell #
