Looking over your requirements, I think it might be helpful to divide the
problem into two parts.  The first is vanilla callback-on-busy, which is
relatively simple to implement.  The second part is "inbound call
management", and using it for callback-on-busy is only on instance.  The two
problems might be as easily solved independently.  Although I'd like to hear
what sort of situation would generate such a heavy amount of
callback-on-busy demand.

I think that this can be solved by restricting the information that is
available in the dialog event notices to un-authorized subscribers.  For
instance, it is possible to construct a dialog event package that tells that
the phone is being used without disclosing any details about that use.
