Do they want the AA to answer immediately or delayed,(or not at all during the day)?
What I would do assuming that they want AA delayed during day:
Make 3 time profiles. Business Hours, Closed hours and Lunch hours.
In your AA, assign the Business Hours profile to the Morning, Lunch to the Afternoon, and Evening to the Closed.
Record a "intro" greeting for each of these. "Thank you for calling, we are closed for the lunch hour" Then, in the menu options recording, record what the caller should do. "Enter the extension number of the person you want, press 0 for the general mailbox....etc...."
Now, you can send calls to the AA using the Hunt Group Overflow to the AA. If it goes there during your time profiles, the respective greeting will play.
If you want, you could make another AA just for Holidays, but someone would need to manually press a button on site to send calls there. You can just use "Hunt Group Out Of Service", send that to a group forwarding to the "Holiday" attendant.
For the day AA, you can use "Set Hunt Group Night Service" on a users phone, and set the backup nught service group as your AA group.
The key is the recordings...make sure you only do the intro's and put what the caller can press in the "Menu Options" recording.....
