asterisk users - Feb 2009 - Obtaining callerid on a PRI for billing purposes (with non toll-free numbers)

I'm thinking of starting a partyline, where people call in and talk to other
people. For record keeping and billing purposes, I'd like to go by the
callers telephone number.

This method works fine as long as the caller doesn't have callerid blocked,
but what are my options if they do block their number? I know there must be a
way to report it, because there is a service provider here in my area that if I
call and block my number, they are still able to obtain it. I know that when
dialing a toll-free number, that the number is reported regardless. But what
about regular non-toll free numbers?

Does anybody have any ideas how I can do this? Are there any providers out there
that offer this service over PRI or some other method?

Thank you in advance.

The old classic is to say something like ' your callerid is blocked,
please get out your credit card'

Some providers will give it to you on a PRI line. If you are using a
TF number you'll get it regardless.
However keep in mind that it takes me about 3 seconds to change
outbound callerid.
