STIR SHAKEN VoIP refers to a comprehensive framework designed to ensure the integrity of caller information in VoIP (Voice over Internet Protocol) systems. This framework addresses the growing issue of caller ID spoofing, which can lead to fraudulent activities and loss of trust in phone communications.

The STIR/SHAKEN solution plays a pivotal role in verifying the authenticity of calls by using cryptographic certificates. These certificates are embedded into the call data. This provides a digital signature that verifies the call’s origin.

This process begins when a call is made. The originating service provider verifies the caller’s identity and their right to use the calling number. Once verified, the provider attaches a digital certificate to the call. This certificate travels with the call through various networks until it reaches the recipient. The terminating service provider then checks the certificate to ensure the call has not been tampered with. If the certificate is valid, the call is delivered as trustworthy.

In STIR SHAKEN VoIP systems, this verification process is crucial because calls are transmitted over the internet, making them more susceptible to tampering. By implementing STIR SHAKEN attestation, service providers can significantly reduce the incidence of spoofed numbers, ensuring that recipients can trust the caller ID information displayed.

Additionally, this framework supports different levels of attestation, providing varying degrees of trust based on how thoroughly the caller’s identity has been verified. This adds another layer of security, helping to combat fraudulent activities and improve overall call integrity.

For more in-depth information on this topic, consider reading the blog titled Understanding STIR/SHAKEN and Its Role in Combating Caller ID Spoofing. This blog offers a comprehensive overview of how the STIR/SHAKEN framework works, its importance in the telecommunications industry, and its effectiveness in reducing caller ID spoofing.

What is STIR SHAKEN Attestation?

STIR SHAKEN attestation is the process of verifying and certifying the legitimacy of a phone call’s origin. This process provides different levels of trust, indicating the confidence of the service provider in the caller’s identity. By doing so, it helps prevent fraudulent activities such as caller ID spoofing and ensures that calls are trustworthy. This attestation is essential in modern telecommunications to restore and maintain trust in phone communications.

The ABC’s of Attestation Levels

Attestation levels in the STIR/SHAKEN solution are categorized into three types, each representing a different degree of verification and trust:

A-Level (Full Attestation)

The service provider has verified the call’s origin and the caller’s right to use the number. This level of attestation signifies the highest degree of trust, ensuring that the caller ID information is accurate, and the call is legitimate. This form of STIR/SHAKEN solution involves a thorough validation process where the service provider confirms the identity of the caller and their authority to use the specific phone number. Full attestation is typically applied to calls originating from within the service provider’s own network, where complete verification is possible.

B-Level (Partial Attestation)

The service provider has verified the call’s origin. However, this STIR SHAKEN VoIP framework cannot confirm the caller’s right to use the number. Partial attestation is used when the service provider can authenticate the source of the call but lacks complete information about the caller’s authorization to use the specific number.

This level is common when calls pass through multiple networks or third-party service providers, where full validation may not be feasible. While this level provides some assurance, it indicates that the verification is not as comprehensive as full attestation.

C-Level (Gateway Attestation)

The service provider can only confirm the call came from their network without verifying the caller’s identity. Gateway attestation in STIR SHAKEN attestation represents the lowest level of trust, where the provider can only authenticate that the call originated within its network. This level does not provide any assurance about the caller’s identity or their right to use the number. It is often used for calls that transit through intermediary networks or gateways, where detailed verification is not possible.

Attestation (In)Efficacy

While STIR SHAKEN attestation significantly improves call verification, it is not foolproof. Several challenges can impact its efficacy, necessitating ongoing advancements and industry-wide collaboration.
