No, you could do it with ISDN too. There are dozens of ways to do it.
Caller ID information is not reliable.

To use VoIP, you need an account with a VoIP provider, you need a VoIP
box in your home, and you need fairly wideband internet access. It is
very profitable for the ISP to bundle the VOiP services along with the
rest of their services, and outsource them to a provider like Level3,
just like they outsource mail and news services in most cases today.
