Device for barring unauthorised phone calls

Hi all
A mate has just had a bit of a shock!!
His 14 year old son has just run up a phone bill of =A3700!!
I'm sure that I've seen a device somewhere that can prevent
"unauthorised" =
numbers from being dialled.
I'm thinking of a bit of kit that plugs in to the master socket (or the
soc=
ket that you want to prevent the unauthorised calls being made from) and
se=
nds an NU tone to the phone when a non legitimate (or would that be
illegit=
imate :-o ) number is dialled.
Has anyone come across such a device?
TIA
Regards
Neil
