Hi.

The solution is definitely developing a well-defined App. Call center are always an indirect way of connection between the driver/the responsible people and the parents. However, in an emergency or urgent situation, both sides want the most direct means to convey the information.

We recently developed a similar closed-circuit App to be used in some of the international schools in Asia, so I can help you to provide the initial guidance on UI/UX related issues.

Thanks,
