Call Guardian STIR/SHAKEN Capabilities

Robocalling Epidemic

The FTC received 4.5 million robocall complaints in 2017, up from 3.4 million the prior year. Robocall bad actors continue to adjust their strategy to elude detection. The time is now to improve your subscribers’ call experience.

What is STIR/SHAKEN?

STIR and SHAKEN use digital certificates, based on common public key cryptography techniques, to ensure the calling number of a telephone call is secure. STIR/SHAKEN will identify Caller ID spoofing, a common technique used by robocallers, by authenticating the Caller ID at the origination point of the call, then validating this Caller ID at the termination point. Operators can use STIR /SHAKEN, in conjunction with Call Guardian real-time analytics, to determine the validity and intent of a call.

Regulators are increasingly applying pressure to carriers to solve the robocalling problem. In the US, FCC Chairman Pai sent letters to 11 voice providers asking those that had not yet established concrete plans to implement the Signature-based Handling of Asserted Information Using toKENs (SHAKEN) framework and the Secure Telephone Identity Revised (STIR) standards to implement such standards without delay. In Canada, the CRTC has mandated deployment of STIR/SHAKEN by March 2019.
