sure, you can just use a call handler (i.e. as opposed to a subscriber). Call handlers have 5 greetings you can configure to play:
Standard - plays during the "day" time
Off Hours - plays at night
Busy - when the phone forwards busy to that number
Internal - when the calling extension forwarded from that number is a subscriber
Alternate - when active it over rides all other greetings
If you record and activate the standard and off hours greeting for a call handler and associate it with an appropriate schedule, calls hitting that handler will get different messages during the day vs. night.
The down side of a call handler is you can't adjust the greetings over the phone conversation as you can with a subscriber... you have to adjust greetings via the SA console.
