Full Attestation (A)
The provider knows the customer, they know the customer has a right to use the originating number, and they know the call originated on their network.
Partial Attestation (B)
The provider knows the customer, but the customer may be using another provider's phone number. The call is legitimate, but the provider can’t fully attest because of missing information.
Gateway Attestation (C)
The provider can’t verify the customer or phone number and has no way of knowing whether the call is legitimate. However, they attest to the call to mark that it originated on their network.

Signing your own calls
Some service providers may be eligible to sign their own calls in the SHAKEN/STIR framework. Take a look at the requirements.
The TRACED Act was signed into law on December 30, 2019, which directed voice service providers to have SHAKEN/STIR implemented on their networks by June 30th, 2021. On June 30, 2022, small service providers were expected to sign their outbound calls with their own SHAKEN tokens.
