VOIP is bigger than just PSTN-gatewayed calls via some specific
company.  The end goal is to connect the VOIP islands directly.  That
is already happening at some large companies where they call their
supplier directly on a purely voip link.  For a concrete example look
at the sip-edu program. It is a growing group of universities that
exchange SIP calls directly.  (Some even have their asterisk and SER
config notes on line.)  In all cases the caller's calling-number and
calling-name stuff will get passed to the callee.
