Regarding the *67 feature to disable Caller ID:
This does not stop your ANI information from travelling with your
call. It just sets the "privacy bit" to on. So standard
consumer-grade Caller ID systems won't see your number. But if the
user on the other end is receiving your call over a T1, they can use a
Dialogic voice processing card to yield your ANI, even with the
privacy bit set.
A *much* better way to do this is the following:
Dial the Operator.
Ask him/her to dial the 800 number for you.
This will result in your ANI being (000) 000-5555 (or at least that's
what it does in Bell Atlantic land). I tested this a couple months
ago using AT&T's 1-800-MY-ANI-IS service. I directly dialed
1-800-MY-ANI-IS and it read back my phone number. Then I had the
operator dial it for me and got (000) 000-5555. This service doesn't
work anymore, YMMV.
