So you mean... like, these are the exit points into the "legitimate" telephone network for, say, those random MedAlert scam calls I keep getting from numbers scattered all over North America? Or if not, what does "VoIP" mean here exactly?

Bingo! And the call's been "verified by the carrier" because it came off the cell network from a purportedly valid SIM... but patched into a dodgy SIP connection back to the scammer.
