Speaking of which, what happened to SHAKEN/STIR? I thought the strong authentication requirements came down the pipe years ago and they were going to start turning off (or hiding by default) routes of low reputation. That was years ago, it was supposed to take years, but here we are years later and I still get loads of spam calls. What happened?
It's worth noting that TFA addresses this in the context of the scam: When the scam depends on the emotional reaction in response to a loved one's distress, it doesn't matter if the number the scam is coming from is unfamiliar. This means that the scam can use "technically correct" numbers that pass SHAKEN/STIR with no loss in conversion.
TFA also mentions that by routing calls through older non-IP networks you lose the accurate information, although it sounds like the FCC is slowly cracking down on this.
It is hard to get vendors to give up revenue no matter how illegal the source of revenue is.
So lots of judicially-unreachable call centers under judicially-unreachable telecoms need to lose reputation score and get spam-binned by default, just like email. I thought that was going to happen by now. Did the US telecoms just chicken out?
Why not fine vendors instead? They'll quickly change the tune..
