AT&T and T-Mobile begin cross-network STIR/SHAKEN
AT&T and T-Mobile announced yesterday, August 14, that they have begun to rollout cross-network call authentication using STIR/SHAKEN.
STIR/SHAKEN is a process where the originating provider authenticates the caller ID and digitally signs the call. The terminating service provider then verifies the caller ID information and signature so they can inform the called party of the verification status.
Most spam robocalls use spoofed caller IDs. STIR/SHAKEN won’t prevent that, but it does give consumers more confidence to answer verified calls. As STIR/SHAKEN becomes widely deployed, it will restore trust in the telephone system.
In their joint announcement, AT&T and T-Mobile said that calls with illegally spoofed caller IDs will fail verification and will not be marked as verified. Calls that are verified will be marked to inform the called party that the calls are really coming from the identified numbers.
