Are you Stir Shaken Compliant?

The Federal Communications Commission (FCC) requires voice service providers to implement STIR SHAKEN framework to impose call authentication technology on Voice over Internet Protocol (VoIP) calls and business communications in North America.
By Being Stir Shaken compliant you can protect your phone numbers from call blocking, spoofing, and spam tagging and deliver an accurate and consistent call display to increase contact rates and engagement while protecting brand reputation.
Easily Verify That Your DIDs Meet STIR/SHAKEN Requirements
As more carriers start to roll out STIR SHAKEN authentication, phone numbers and call sources will be meticulously verified for attestation levels. Our BYOC STIR/SHAKEN Verification tool can help you identify your attestation levels and assist you to build trust and confidence in your voice calls.

What are Attestation Levels?

In a STIR-SHAKEN call, the originating service provider attests via data in the SIP header to their relationship with the caller and the caller’s right to use the calling number.  One part of the data is the Attestation level.  There are three levels of attestation that can be applied to a call:
“A” Attestation — Full
The voice service provider knows the end-user customer and their right to use the phone number.
“B” Attestation — Partial
The voice service provider knows the end-user customer but not the source of the phone number.
“C” Attestation — Gateway
The service provider has originated the call onto the network but cannot authenticate the call source e.g., international gateway.

Once a call has been given an Attestation level, that level may not be changed by another carrier.
