STIR/SHAKEN Robocall Mitigation Plan

STARPHONE LLC maintains full compliance with FCC STIR/SHAKEN requirements and implements comprehensive robocall mitigation measures to protect our customers from unwanted and fraudulent calls.

What is STIR/SHAKEN?

STIR/SHAKEN (Secure Telephone Identity Revisited/Signature-based Handling of Asserted Information Using toKENs) is a caller ID authentication framework designed to combat illegal robocalls and caller ID spoofing.

Our STIR/SHAKEN Implementation

STARPHONE LLC has implemented a comprehensive STIR/SHAKEN solution that includes:

Attestation Levels

• Full Attestation (A): The service provider can attest to the authenticity of the calling party's identity
• Partial Attestation (B): The service provider can attest to the origin of the call but not the calling party's identity
• Gateway Attestation (C): The service provider can attest to the call's entry into their network

Authentication Process

1. Call Initiation: When a call is placed through our network, we generate a digital signature
2. Identity Verification: We verify the caller's identity using our authentication systems
3. Attestation Assignment: We assign the appropriate attestation level (A, B, or C)
4. Signature Creation: We create a digital signature containing the attestation information
5. Call Routing: The call is routed with the STIR/SHAKEN signature to the destination
