T-Mobile, Comcast Turn on Call Verification Between Networks in Latest Robocall Fight (usatoday.com)
pgmrdlm shares a report: Calls between T-Mobile users and Comcast's Xfinity Voice home subscribers will now be "verified," the latest move in the ongoing fight against robocalls. The two companies announced Wednesday that they have launched cross-network verification, allowing users to know that the calls they are receiving is from an actual person and not a spammer or robocaller.
They use a handoff system recommended by the FCC where the caller's network verifies that a legitimate call is being made with a "digital signature." The recipient's network then confirms the signature on its side. A number of major wireless and traditional home voice providers have pledged support for the verification method, including Verizon, AT&T, Sprint, Charter, Cox and Vonage, with several announcing plans to roll out or test the feature in 2019.

This seems like something that should have been done...forever?
What if the large carriers all implement FCC's SHAKEN/STIR between them but then refuse to do the same thing for all the small carriers ?
Then start marking all non-verified calls as SPAM ?
Don't say it could not happen.
