I did an LRN lookup for that first one, and it's currently ported to
Onvoy, one of the brands of Sinch. But again, that only tells us how to
get a call TO that legitimate owner.
It's worth noting that the 463 area code in Indianapolis is pretty new -
only a couple years old in practice. I would expect records of who has
what to be pretty clean at this point. There shouldn't be a whole lot
of serial port (no not that kind) activity on 463 numbers yet, and if
you find it, that might be an indication of nefarious activity on its own.
One level of port from an established CLEC to a VoIP carrier is pretty
normal from my (limited) experience, though. Most VoIP carriers don't
have direct assignments even if they could get them. They mostly just
seem to get them from established CLECs.
