Not sure if this has been mentioned, but yesterday was the day for STIR/SHAKEN technology to be in place to prevent spoofed robocalls. Not sure if this will mitigate all robocalls, but the number spoofing should be curtailed.

I'd forgotten that! I got a spam call at 7:46 PM yesterday. Haven't had one since. But I've gone a couple of days between spam calls before.
Interestingly, I can't find much in the news about this. Has anyone noticed a change?
