Currently I go to Phone System, Auto-Receptionist, General Settings, IVR settings then custom answering rules. I add a custom answering rule for each day of the month to let the system know which EMS doctor is on call from 8 AM - 10 PM that day. Then the team wants it on the Google Calendar, so I go into google calendar and add who is on call for each day of the month. LOTS of room for error and VERY time consuming. Please consider.
