I got involved in a conversation with my Pacific Bell friend last week
about just this issue.  He's working on implementing all the new SS7
stuff on the DMS-100's.  Apparently, they consider the person actually
placing the call to be the "Caller" with respect to "Caller ID."  It
doesn't matter if there are several "hops" of forwarding - the
original number will display.

Also, we talked about how this works with ISDN.  There will be display
sets which can display both the calling number and the called number.
So, a secretary, upon receiving a call, can tell not only the number
of the calling party, but the number they called (very useful in the
case where the call no-answer transferred to the secretary, and where
there are several numbers that no-answer transfer to the same place).
Of course, I just had to ask the question: "What if there are several
hops of no-answer transfer or call forwarding?"  In this case, the
original calling number and the original called number will be
displayed, regardless of any subsequent transfers.  This gives the
answerer complete information: who is calling, and who they think they
called.
