How about with VoIP, has anyone figured out how to correlate an IP
with phone number?

The IP that will show id the MAIN IP of the router unless your making
internal VoIP calls, NAT will mask the internals.

Greetings in return,


A Simple Answer: No.

A Longer Answer: No - At least not without a court order. IP addressing
has nothing to do with the telephone numbering system - and most IP
addresses are dynamic in the first place (as in, the IP address is
different every time the subscriber connects to the Internet) - but you
may 'request' (see "court order" in the last sentence) the contact
information of a subscriber who was using a certain IP at a certain
time, under certain circumstances, from their ISP.
