I'm pretty sure that you received responses the first time around that
essentially said, "This is provider dependent".

On our H.323 gateways, we put "clid restrict" in the dial peer for
calls that we want to go outbound without caller name or number.

As far as providers, we've found that ATT honors the "don't send
anything" that we configure on our dialpeers, but Verizon was
inserting the BTN (billing telephone number) if we did a clid restrict
and we couldn't convince them not to, so once our contract expired we
cancelled our PRIs with them.  This may or may not still be the case.
