STIR/SHAKEN to prevent caller ID spoofing

Question

The TRACED act and STIR/SHAKEN are supposed to put the onus on the carrier to verify caller IDs are legitimate, yet I see no evidence of this.  At home we receive 6-7 calls per day from spoofed caller IDs, for funeral planning, health insurance, solar, etc.. Most seem to originate in India. Technologically it would seem possible for Verizon to verify that if a call doesn't arise from the area the caller ID indicates, it's spam. CANSPAM and Do Not Call Registry obviously don't work, since the callers don't abide by them.  Any suggestions?

I ended up purchasing a business telephone system (complete with an auto attendant) for the house. Callers need to get past the attendant before the telephones will ring.

The type of equipment used by telemarketers won't forward the extra digits to allow the call to get through, so they just end.  Caller ID records are the only visual indication that something tried to call in.

To be fair to Verizon, this is a, issue across the board with landline customers of other providers running into the same problem.

In the past, people ditched their landlines due to the amount of spam calls being received. Even mobile phones are not immune to telemarketers...I get more than my fair share on mine. I doubt that porting a telephone number to an Internet-based company such as OOMA (or even getting a telephone number directly from such a provider) would help as telemarketers can dial numbers sequentially.

For a while, calls from verified telephone numbers to Verizon landlines had a [V] in the CDR to indicate that the call was from the actual number. While it worked to some degree, I would still receive calls from verified numbers that had been recently disconnected.

I don't have an answer. Whatever can be done, it needs to start with getting all providers to fully update the LIDB and programming network equipment to disallow calls from vacated telephone numbers with limited exceptions (doctors who wish to keep their telephone numbers private for example).

Not a comprehensive solution, but it is a start.
