OS X server: can you restrict iOS devices to only call certain numbers?
I'm looking for a way to restrict the callable phone numbers iOS devices managed with OS X Server can call. I want to do this stealthily so the end user does not know, and cannot block me from doing it. Before I invest too much time it would be nice to know if it is even possible.
Teenager a little too social during school hours and would like to lock his phone down when needed so can only call mom or myself.
