alt Hacker NewsJust because a call is a spam call doesn't mean it is spoofed. STIR/SHAKEN ends spoofing but anyone can ultimately buy a phone and make calls that are spammy.

Sure, but with phone numbers that can't be spoofed, telcos can terminate service, and filtering technologies can block calls. Spam gets expensive if you have to buy new service every five calls.

Nobody is making spam calls with cell phones. Spammers use VOIP services and old TDM systems.

Spoofing isn’t ended at all
Almost every spam call has that I get, is spoofed.
Someone here explained it, once.
I think the spoofed calls use a legacy transport tech that can’t be forced to validate.
