I have set an auto attendant to automatically play the day and night mode based on business hours on Unity Connection with CUCM 8.0. But client wants to turn on the night mode manually when the receptionist is leaving before the closing hour, and turn off the night when come in early. And they still want to play the day greeting during normal business hours. Which option available in Unity Connection that can handle this. I can set up night mode manually ok, but will lose out the day greeting. How can I achieve this with both day and night greeting.
