I've seen references to devices that you can hook up between the phone that
can be programmed to only allow certain numbers, with passwords & such. I'm
sorry I can't provide more detail--this came up when 976 blocking was 
being discussed some time ago. 
You'd probably be better off looking in comp.dcom.telecom (a moderated
group). That's where them gnarly phone dudes hang out... :-) Mail your
question to telecom@eecs.nwu.edu, and watch there for a couple of days.
You should get answer(s).
