What Is STIR/SHAKEN Caller ID Attestation Levels?

In the realm of modern communication security, STIR/SHAKEN has emerged as a vital framework, and understanding its Caller ID Attestation Levels is key to appreciating its efficacy.

What are STIR/SHAKEN Caller ID Attestation Levels?

STIR/SHAKEN introduces three attestation levels, denoting the degree of certainty in authenticating the caller's identity:

1. Full Attestation (A):

Represents the highest level of confidence in the caller's identity. Service providers asserting Full Attestation have verified both the origin and identity of the caller.

2. Partial Attestation (B):

Indicates that the service provider has authenticated the call but may lack complete information about the caller's identity. Partial Attestation assures a certain level of verification but falls short of the thoroughness achieved with Full Attestation.

3. Gateway Attestation (C):

Represents the lowest level of attestation. Calls with Gateway Attestation imply that the service provider offering this attestation has authenticated the call to some extent but might lack specific information about the caller's identity.

Importance of Attestation Levels in VoIP:

1. Enhanced Trust:

Full Attestation builds the highest level of trust, assuring call recipients of the verified identity of the caller. This is crucial in combating caller ID spoofing and fostering trust in VoIP communications.

2. Robust Security Measures:

The differentiation between attestation levels enables call recipients to gauge the reliability of the provided caller ID information. This empowers users to make informed decisions regarding call legitimacy.

3. Fraud Mitigation:

By incorporating these attestation levels, STIR/SHAKEN significantly reduces the risk of fraud and malicious activities. Users can confidently engage with calls, knowing the level of authentication applied to the caller's identity.

4. Regulatory Compliance:

Adhering to these attestation levels ensures compliance with regulatory requirements. This is particularly important as regulatory bodies increasingly mandate the implementation of STIR/SHAKEN to combat unwanted calls.

In conclusion, comprehending STIR/SHAKEN Caller ID Attestation Levels is pivotal for both service providers and users in the VoIP landscape. It establishes a standardized framework for authenticating caller identities, leading to increased trust, heightened security, and effective fraud mitigation in the evolving landscape of modern communication.
