[comp.dcom.telecom] What Number Is This Anyway?

Recently I was using a payphone and wanted a friend to call me back.
Unfortunately, as is sometimes the case, the payphones number was no
where to be found.  I tried to get it from the operator but it seems
phone companies will not tell you (under pain of death) what phone
number you are calling from.  Later on I found that dialing 311 usually
spits it out at you but it doesn't seem to work on all phones.

I wonder if anyone knows a sure fast way of getting the phone to give
you this privilaged information why they are so set on keepingcompany
to give you this "privilaged information" and why they are so intent
on keeping it from you.

In New York City, there is a special sequence of numbers you can dial
to reach a computer which will do various things for you if you know
the codes to enter.  Among them are:

   Read back the number you called from
   Call you back (it keeps calling until you keep it off the hook
   for a while)
   etc.

I don't know if it is still in use, and I have not seen it work in any
other area, so I won't confuse anyone by mentioning it.
