[comp.dcom.telecom] Preventing 900 Call Abuse

KATH MULLHOLAND <K_MULLHOLAND@unhh.unh.edu> (04/23/91)

In an ideal world, only those who are authorized to pay for a service
would be able to order or use that service.  For the most part, we can
do this.  The problem areas are mail order and telephone services.

900 numbers can be dialed without any forethought about where the money
will come from to pay for the calls.  A friend's daughter ran up over
$3000 worth of these calls in one billing period.  The daughter, 13,
is by no means an adult, able to make a contract for that kind of
money.

When my friend called the phone company, she got nothing but grief.
One representative said, "If you can't control your daughter, you
can't expect us to take you off the hook."  Her daughter probably was
out of control, and has gotten in other kinds of trouble since, but
the real issue is, who is liable when a child makes a contract that
the parents have not authorized?  This, to me, is the key sticking
point of 900 services.

Possible solutions abound:

One mother I know puts a rotary phone with a "dialing block" on it so
that the phone can't be dialed at all.  (I'd worry about emergencies.)
Another puts her phone set in her trunk when she goes to work each
morning.  (Emergencies still are an issue.)

But the most elegant solution I've heard is to remove the PIC from the
home telephne line, in essence removing all ability to make inter-LATA
calls.  This has the added benefit of being unable to call your
out-of-state in-laws ...

This is not only not an elegant solution; it is not a solution at all.
In a similar manner to the way 800 calls are handled, a call to a 900
number is routed to the carrier that is furnishing the 900 transport,
NOT to your PIC. Removing the PIC would not stop one single call to a
900 number. And even if it would, how much trouble would it be for
someone to dial 10XXX to access any carrier? Removing your PIC does
not disable interLATA long distance by any stretch of the imagination.
And it will not even slow down carrier-specific calls such as 800/900.

This is indeed the only real method to effectively handle the problem
of unauthorized calls to 900 numbers. It also should end the constant
discussion over contracts, uncontrollable children, etc., etc. This is
offered by Pac*Bell (and many other LECs, no doubt) at the time
service is applied for. If a person declines blocking (or fails to
order it when faced with a potential problem) then there really should
be no slack cut by the LEC at bill time.

With the advent of free 900/976 blocking, this whole debate can be
concluded at long last.

But the PIC only specifies which LD carrier gets your 1+ calls.  Does
this also stop 10288-1-900-xxx-xxxx?  I would think not.  No, I'm not
going to try it at home.  :-)

One hopes said mom's flock doesn't learn how to hook-tap the phone.
Said trick is my favorite bit of phone trivia; I estimate that maybe
2% of the population knows it is possible to dial "without dialing."

[Moderator's Note: Certainly hook-tapping will work, but the smaller
digits are easier to achieve with accuracy. Tapping out nine, ten and
ten more (as in 900) can be tricky unless your finger is agile and
quick, and your timing very precise in offices which require it.   PAT]

Years ago (how many, I won't say <grin)) I went to work for Northern
Ohio Telephone Co. as an installer/repairman after graduating from
high school.  I remember amazing some friends who worked at a local
restaurant by hook-tapping a call I needed to make on thier
'dial-less' phone.  Were I smarter, I would have gotten them to place
a bet.
