I do not know what carriers will tariff, but I have a copy of the 5ESS
Switch Feature Handbook, AT&T select code 235-390-500.  The version I
am looking at is copyright 1988, so there may be a more recent
publication.  In the 5E6 generic, which is described as information
for planning purposes, not commitment to deliver any particular
features, there is a feature that allows selecting the caller ID
displayed to be either ANI (billing number) or calling party number,
either as the preferred or exclusive choice.  Note that 5E6 has not
been released yet.  Also listed under this feature is the capability
to block originating information on a per-call or per-subscriber basis
(for at least ISDN origination, it was not clear if both options are
supported on non-ISDN lines).

In order to have inter-LATA calling line ID, the end to end signalling
must be Signalling System 7.  For local calls to have calling # ID,
SS7 must be deployed locally.  I do not know how many, if any, local
switches are connected to long distance companies, which would prevent
inter-LATA Call ID.
