STIR/SHAKEN Hosted Signing Service

Effective May 29, 2025, Bandwidth offers STIR/SHAKEN Hosted Signing Service (HSS), which aids in complying with the FCC’s Third-Party Authentication Order’s call signing requirements, enabling you to sign your own calls with your own certificate without the need for in-house software or hardware. 

Using HSS, you can now easily load your STIR/SHAKEN certificate onto the Bandwidth platform and assign call attestation levels based on your own call signing policies. For more information or to sign up for HSS, check out our product tour or talk to a product expert.
