There is a number you can dial to obtain the telephone number that you
are calling from.  I got this number off of the RIME BBS Network
"Phones" conference.  I have tried it and it works, even from a U.S.
Government Centrex number.  I do not know if there is a charge for the
call, as I do not remember seeing it on my phone bill.

The exact number to dial is:

    10732-1-404-988-9664

Note this is a special number using the 732 network, a private network
operated by AT&T.

After a tone, it reads back the area code and phone number placing the
call, then what apparently is a checksum digit.  At this point it no
longer has the ANI information and then reads back all zeros.

If AT&T is charging for this; all well and good, they are not likely
to drop it; if not, please be prudent in using it so as not to see it
cancelled.


Paul Robinson - These opinions are mine (Who else would want them?)
