One point here- you are not actually suppressing the transmission of your phone number. It is transmitted *between switches* in any case- you are simply suppressing the transmission from a switch to the destnation phone. This is important in relation to the phone company recieving data, as well as the distinct possibility that a clever person could still get this. I got the above info out of Phrack Magazine (_Caller ID Technical Details_ by Hyperborean Menace #45-06, still being issued as I write this).

call through multiple long distance companies. Since the LDCs don't talk to one another, this should increase the difficulty of tracing and/or tapping a call. Does anybody know how to do this?

Don't know, but from what little I know about the phone company, I would assume using the demand-dial numbers (like 102880) for ATT) from another long distance phone would be a start. jamie
