Here is the a brief overview of the config. We have a BCM 400 4.0 with a PRI. We have the lines being answered by the receptionist during the days (8-5) and then WANT the night greeting to auto hange to night mode. We have the greeting recorded and the table set to start playing the night greet at 5pm untill 7:59am. what could I be missing? Any help would be great!!
