Blueprint Numbers Attestation For Free

A status (Full Attestation) ? The service provider has authorized the call as coming from the correct origin, so consumers should feel confident answering their phones. B status (Partial Attestation) ? The service provider can verify where the call comes from but cannot verify that the caller owns the number.

"Gateway Attestation", "C", indicates the call can only be verified as coming from a known gateway, for instance, a connection to another service provider.

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.

Gateway Attestation (C) ? The service provider has authenticated from where it received the call, but cannot authenticate the call source. An example of this case would be a call received from an international gateway.

CPA Exam Blueprint is a document that presents a detailed content listing of each CPA Exam section and is published by the American Institute of Certified Public Accountants (AICPA) once or twice annually.

Partial Attestation (B) - The originator knows the identity of the caller, but cannot confirm their right to use the Caller ID. Gateway Attestation (C) - The identity of the caller is not known, as the call originated outside of the network, or internationally. C level is applied when A or B cannot be.

Essentially, the attestation levels are designed to protect the integrity of the telecom networks and provide a way to signal confidence levels to other carriers that the calls can be trusted, and at what level.
