I need to setup a call handler that is pretty specialized: it must answer the phone from 5PM to 8AM, but during the other hours, 3 phones must ring when someone calls the main number.

The phone line comes in POTS on a 2801, and under the interface port it says "connection plar 4074". In Unity, the extension given to this greeting is 2002.

Should someone call during "open hours" we must ring the 3 phones, thus in CCM there is a line group defining these 3 phones. So somehow, when a call comes in the 2801, we are handing it to the plar, ringing the 3 phones, instead of hitting the Unity greeting. Of course, we only want to hit the Unity greeting between 5PM and 7AM, the rest of the time, we want to ring those 3 phones. (And I don't see a way to do that in Unity, i.e. during closed times ring the plar)

Is that kind of clear?? How would I get this setup properly??

Thanks for any help!
