Feature Header Attestation For Free

If the call is authenticated the Verstat Parameter would be updated as ?TN validation passed.? If the call is not authenticated, then the terminating service provider would set it ?TN validation failed.? In this case, they can also block the call.

STIR/SHAKEN digitally validates the handoff of phone calls passing through the complex web of networks, allowing the phone company of the consumer receiving the call to verify that a call is in fact from the number displayed on Caller ID.

1. The verstatparameter is a tel URI parameter within the P-Asserted-Identity header or the From header. P-Asserted-Identity: tel:+15617500080;verstat=TN-Validation-Passed. There are currently three different options to convey verification results through the verstat parameter: TN-Validation-Passed.

VERSTAT is not a PRIVACY PROTECTED parameter and provides value to the originating and terminating networks without disclosing the originating identity and/or calling name or number. Device Display Framework along with CVT MUST provide this valuable information to end user.

Attestation. In a STIR/SHAKEN call, the originating service provider signs (or attests) to their relationship with the caller and their right to use the calling number.

A validated call (TN-Validation-Passed) simply means the call was signed and an attestation provided by the originating service provider, and the authentication header was validated by the terminating service provider.

SHAKEN stands for Signature-based Handling of Asserted information using toKENs. It is a specification designed to mitigate unwanted robocalls by reducing the impact of caller ID spoofing.

If the call is authenticated the Verstat Parameter would be updated as ?TN validation passed.? If the call is not authenticated, then the terminating service provider would set it ?TN validation failed.? In this case, they can also block the call.

Attestation is a crucial part of the STIR/SHAKEN process and includes three categories to determine essential information about the caller by evaluating the ?attestation? level of each call. These attestation levels distinguish a caller's validity to use a specific number.
