Survey (of n=1) says: nothing has changed, aka the new technology is not working. I just received the same kind of recorded message call of "something something renew auto warranty" on my AT&T u-Verse line. This time when I called back the displayed caller ID number it was ring-no-answer, versus the previous "you have reached a number that is no longer in service". By terminating the call the carrier made probably more money than it would cost them to enforce the new rules.

Other than the donotcall.gov portal, is there a new way to report the obvious failure of STIR/SHAKEN?
