Complete Header Attestation For Free

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.

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.

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.

It does this by digitally assigning an attestation rating to a call, indicating whether the originating carrier has authenticated the right of the caller to use the phone number. The receiving carrier uses a decryption key and the attestation rating to validate the caller's number and help identify spoofed calls.

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.

The origid , standardized as part of STIR / SHAKEN, represents the originating point of a call in each network and opens up the possibility of streamlining the traceback process. The third is potentially to provide some form of display to the end user that the caller ID has been verified.
