[comp.dcom.telecom] Credit Card Good For One Number Only

HAMER@ruby.vcu.edu (ROBERT M. HAMER) (09/28/89)

I think that aspects of this issue have been discussed on the digest
before, and if they have, if the moderator would point me to the
appropriate issues, I will FTP them (unless the question is of
sufficient general interest that it might bear discussion).

My daughter just left for college (hooray).  When she left, my wife
gave her our Sprint Fon Card number so that she could call us
(probably a dumb move, or at least not well thought out).  We got our
first post-daughter-departure Sprint bill yesterday.  In addition to
two or three calls to us, there were calls to friends and relatives
all over the country.

To state the specifications first, without contaminating possible
solutions with my own thoughts, I would like her to be able to call us
at our expense, but I have no particular desire to pay for any other
long distance calls she chooses to make.

I think I have read discussions in this digest about (a) a relatively
cheap residential 800 number, and/or calling/fon/credit cards that are
valid only to call one number.  Anyone have any suggestions?

[Moderator's Note: The AT&T Calling Card with a restricted PIN is
known as the "Call Me" Card. It is free for the asking, and the PIN is
limited to calling only the number to which it is assigned; in this
case, that would be your home phone. They issue a plastic card with
this PIN, but it is pointless to hand it out. You would simply tell
your daughter that henceforth to call *you, and you only* she would
dial zero, plus the area code and your number. When she hears the
tone, dial only the four digits of the (new, and restricted) PIN,
followed by the # sign to speed the call on its way. Attempts to call
other numbers with that PIN will fail. Of course, you'll need to tell
Sprint to cancel your existing full service PIN and issue a new number
which you don't give your daughter, otherwise she may continue using
the old one anyway. Anyone who has knowledge of the restricted PIN can
use it in the same way, to call your number only. If calls are placed
through some AOS outfit, there is no guarentee of course that the
restriction on the PIN would be honored, but you will find that out
soon enough and can refuse payment if necessary. PT]
