MCD 8.0 introduced "Business Schedules"
This feature allows you to create up to 100 weekly Business Schedules, which you can then assign to individual directory numbers (DN) listed in the Call Rerouting form. The system uses the time of day and the assigned business schedule (not the system's Day/Night Service schedule) to determine which of the three possible Call Rerouting Always Alternatives should be applied to the particular destination DN. If you do not assign a business schedule to a DN, then the Reroute Always alternate follows the system's Day/Night Service schedule.
