Hi
Well i have never done this without a ATT console being present,,, not to sure how to proceed,, my thinking is maybe a day IDC table and a night IDC table with a key programmed to DRC on a set to toggle between them, but this is not a good solution, if you have people working late they will not see any calls if night service is running..all this is no good if the DRC key is not set when the last person leaves the building ...I will ponder this, maybe someone else will have a better solution...sorry
