Free automatic callback service?

Question

I seem to recall a trick w/ phones in which you dial x*x-last 4 digits of the phone #, hang up, pick up the phone, wait for a funny tone, hang up again, and then your phone would go off.

Does anybody know of this trick and what the magic #'s are?

Answer 1

From what I recall it used to be 579-XXXX or 979-XXXX.  The trick used to work but I think the phone companies disabled it.  I believe it was a test function for pay phones, as I used to do this and then the pay phone would ring endlessly...
