We have added an option to limit the amount of times a parent can call in a specific duration of time (For example 60 seconds).
With this option enabled, if a parent calls 2 times in one minute they will here the following "You called already in the last minute, please wait a minute to call again".
Then the system will NOT disconnect the call, rather the system will allow the parent to select a bus and hear its current location, but without any route information.
This is similar to to how the system would behave if your server is down (See https://jlssolutions.com/qa/162953/parents-can-now-hear-the-gps-location-even-school-server-down)
This option is per phone number, so if they call once from the home and once from the cell the system would not limit them.
If you would like to have this option please contact 718-305-6762 Ext 3
