T-Mobile & AT&T Working Together to Fight Spam Calls

Smartphone users always complain about the robocalls or spam calls they receive. And the complaints are all with valid reason.

Fortunately, the U.S. government, along with the big wireless networks, are all working hard to eliminate these calls. One way the Federal Communications Commission (FCC) is doing this is by imposing new authorization standards known as Secure Handling of Asserted information using toKENs (SHAKEN) and Secure Telephony Identity Revisited (STIR). With SHAKEN/STIR standard, carriers can verify whether the individual making a call is the same person using a phone number on an incoming call. This way, incoming calls from stolen phone numbers can be stopped.

In addition to this, T-Mobile and AT&T have rolled out call authentication technology on calls made between their networks. The announcement made today will allow the two networks to work together in combating scam calls.

Soon, phone calls made between the two networks using a compatible device will result to a "Caller Verified" message. What this means is that the recipient of the call will know that the incoming call is not from a spammer or robocall. AT&T says it is also working on integrating data used by its Call Protect service into this system.

This rollout is the U.S. mobile carriers' latest step to combat robocalls. It also comes after FCC chairman Ajit Pai ordered mobile carriers to implement a call authentication system before the year ends.
