Not all have implemented it yet. But if you haven't. You were supposed to implement some kind of robo calling mitigation plan (Or atleast certify that you have one). At $dayjob we're fully deployed (inbound and outbound).

I received my first ever STIR/SHAKEN signed (iPhone Check mark, highly scientific) spam call on my personal Cell phone on 6/30. It was a Telnyx number. Had the call terminated to $dayjob network. I fully would have collected all various information and ticketed it with Telnyx.

Time will tell how truly effective this is. But we have better originating information now (breadcrumbs) to follow back to the source.

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?
