"Caller-ID" is a POTS only feature, it isn't part of the ISDN call
setup. What *is* part of the ISDN call setup is the originating and
destination numbers. This info provides "caller-id" like features and is
what gets converted to real "caller-id" on POTS lines.

This is also why caller-id blocks don't work on ISDN lines. You can't
block the call setup data on ISDN. If you always want to know who's
calling no matter what, use ISDN.
