We would like both the desktop apps and the smartphone apps to ring at the same time for every member within a group. We would like to set up 2 groups, an East group and a West group. From the hours of 7:00 am to 5:00 pm EST the East group will ring first (all members at the same time.) If no one answers the call it will roll over to the West group (all members will ring at the same time). At 5:01 pm EST the West group will ring first . If no one answers the call it will roll over to the East group until 6:59 am EST. I have been told this is not possible??
