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.

What is SHAKEN/STIR? SHAKEN/STIR is a caller authentication framework meant to help restore trust by reducing fraudulent robocalls and illegal phone number spoofing. SHAKEN stands for Signature-based Handling of Asserted information using toKENs, and STIR stands for Secure Telephone Identity Revisited.

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.

The STIR/SHAKEN framework, an industry-standard caller ID authentication technology, is a set of technical standards and protocols that allow for the authentication and verification of caller ID information for calls carried over Internet Protocol (IP) networks.

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.

Basically what SHAKEN/STIR does is verify calls that are coming to your phone. Robocallers have turned to neighborhood spoofing or replicating a number within your area code that looks familiar to you so there's a better chance of picking up the phone.

In the STIR/SHAKEN framework, originating service providers are responsible for authenticating calls. they originate onto the telephone network. This is done by digitally assigning an encrypted attestation. rating asserting the degree of confidence that the caller is entitled to use the indicated phone number.

Twilio received the SIP INVITE, with a SHAKEN PASSporT, and was able to fetch the public certificate of the originating service provider from the Certificate Authority that signed the call to verify that no one tampered with the SIP INVITE during transit. Attestation level A.

The STIR system aims to add information to the SIP headers that allow the endpoints along the system to positively identify the origin of the data. This does not directly prevent the ability for a robocaller to spoof a caller ID, but it does allow upstream points to decide whether or not to trust that ID.
