Or for companies that dont share it, this is sometimes the issue for
foreign originated calls.  Caller id is sent via SS7, and some companies
that do have caller id, and do have SS7 for other aspects for some
reason do not transfer it globally.  I have seen this from calls from
the UK to the US for example (but not all such calls).

In America the FCC basically requires that if you have caller id support
you must pass caller id data, so most companies in the US pass caller
id.  The federal government however always seems to pass 000-000-0000, I
guess to keep it 'private' but not trigger any privacy blockers so the
call goes through.  MCI sales team used to pass 'out of area' for the
same reason.
