Is there a way to block all outbound calls for a specific device pool to a time zone before or after a certain time? We need the ability to block outbound calls to all time zone with an 8am time zone respective time. For instance, we are in CST and the time is 7:30am, we need to block calls going to every time zone but EST, then at 8am allow calls to EST and CST but block MST and PST, and so forth. Then at 8pm CST block calls to EST, but allow calls to CST, MST, and PST, and at 9pm block calls to EST and CST but allow calls to MST and PST, and so forth. Is there a way that this can be done?
