AT&T and Comcast said Wednesday that they can authenticate calls made between the two different phone providers' networks, a potential industry first and the latest in the long-running battle against spam calls... The system, which uses a method developed in recent years, verifies that a legitimate call is being made instead of one that has been spoofed by spammers, scammers or robocallers with a "digital signature." The recipient network then confirms the signature on its side. The companies said consumers will get a notification that a call is verified, but exactly what that will look like is not yet known.
Both AT&T and Comcast will roll out the system to home phone users later this year at no extra charge. AT&T also said it will introduce the feature to its mobile users this year... Other major wireless and traditional home voice providers have pledged support for the verification method, including Verizon, T-Mobile, Sprint, Charter, Cox and Vonage, with several announcing plans to roll out or test the feature in 2019.
The day Comcast and AT&T made their announcement, AT&T's CEO was giving a live interview that was interrupted by a robocall.

Blocking numbers is pretty useless. The number you see on the called ID most of the time is NOT the number they call from. Number spoofing is an epidemic now and many times if you block a number, it might be completely not involved in the call, it was just spoofed. And a few minutes later, they can call you from another, spoofed number. This needs to be addressed by phone providers (not sonic, higher up the chain) by adding number authentication to prevent spoofing. Until this is done, nothing will work.
