   No, such a beast does NOT exist - except in areas where the TelCo is testing
a somewhat old yet still not implemented SS called LASS (also CLASS).  Anyway,
the feature is ICLID (Individual Calling Line ID or similar), and I think the
only place currently testing is the Philadelphia/Lancaster PA area.

   HOWEVER.  Some TelCo lines as well as lines leased (very expensively) by
private companies (nearly *always* LDS carriers!) CAN be equipped with a little
CO assistance i]to at least have the calling line's number available, if not
always automagically displayed.  (This is called ANI, automatic number ID, and
is not something they really want to talk about.  I mean, it's all over the 
Bell Tech Journals, and you'll occasionally see them bragging about ESS, but
they don't like questions.)
