Competitors put differences aside to fight unwanted robocalls for customers.

AT&T and T-Mobile have begun the rollout of cross-network call authentication technology as part of an ongoing effort from both companies to reduce unwanted calls. This means calls between the two networks can now be authenticated.

The newly implemented SHAKEN/STIR technology helps customers verify whether an incoming call is coming from the number listed on the caller ID display or is a spoofed robocall or scammer.

For example, a call that is illegally spoofed or shows a faked number will fail the SHAKEN/STIR Caller ID verification and will not be marked as verified. By contrast, verification will confirm that a call is really coming from the identified number or entity.

According to T-Mobile, U.S. mobile customers received nearly 48 billion robocalls last year, which means that on average, a customer got more than 150 unwanted calls in 2018. While authentication will not solve the problem of unwanted robocalls by itself, it is a key step toward giving customers greater confidence and control over the calls they answer.

Caller Verified is T-Mobile's implementation of the new recommended STIR/SHAKEN industry standards. T-Mobile customers with an eligible device will see "Caller Verified" on their smartphone when a call has been verified as authentic by the network.

The SHAKEN/STIR technology will be part of AT&T's Call Protect service, a free mobile app that helps customers take more control over nuisance calls. The U.S. carrier plans to automatically add AT&T Call Protect to millions of AT&T consumer lines at no charge.

The U.S. Federal Communications Commission has given wireless carriers until the end of 2019 to voluntarily adopt the SHAKEN/STIR standards. The acronym stands for Signature-based Handling of Asserted Information Using toKENs (SHAKEN) and the Secure Telephone Identity Revisited (STIR).
