Again, believe it or not, there ARE legitimate reasons for spoofing a number, so completely outlawing or preventing spoofing is NOT the answer. As for 'knowing what number it really came from', it's not quite that simple... Many times the CID information is transmitted by the source system, such as my companies phone system (which is likely more or less how the malicious spoofers do it) - but while there may not be a true source number to go by, as I said before, I would imagine the ability to trace the entire call route from source to destination is there, and that would get you to the origin port at the origin CO, thus let you trace it down to a service address. Phone numbers are often only tied to locations in the way you're thinking of with residential service - a phone number is tied to a specific CO port, which goes over twisted pair to a residence. This kind of service likely would not even allow spoofing. Locations being served by PRIs or SIP are an entirely different animal. This is of course assuming they are originating within the US - if they are actually coming from outside the US, then all bets are likely off.Again, I am asking that the FCC stop telephone providers in the US from allowing spoofing. They can stop spoofing from every phone in the US. They know the phone number from which every call comes. For calls generating outside the US, they can at least identify the country it is coming from and prevent spoofing with a US phone number.
One of the legitimate functions of government is to enforce prohibitions on fraud, including creating and enforcing prohibitions on commercial entities aiding and abetting fraud.
And again, thank you for rational and respectful disagreement.
As we always say with regards to gun laws, we don't need more laws, we just need to enforce the laws that are already on the books. Put a way to report spoofed calls in place that includes the previously mentioned trace data, such as maybe a * code after the you hang up on or decline the call, and start going after the malicious spoofers with the laws and fines already on the books.
