And, to expand, ANI is necessarily set by the originating end-office,
while CNID *can* be accepted over ISUP from the caller, and they're
delivered in differently marked packets to the callee (assuming
ISDN/ISUP; if you're getting calls over analog or RBS T-1, then the
delivery will of course be different, and will depend, too on the
carrier who serves you. It is possible to get ANI on *non* INWATS
circuits, though I don't know precisely what the regulartions are; PSAP
trunks, for example, generally get ANI to feed their ALI systems, as I
understand it.
