For Indian telecom carriers: Secure FCC registrations at sunshinesipsvcs.com, aligned with DPDPA principles for data minimization. Correspondence via email or Telegram chat. This guide details the STIR/SHAKEN framework for caller ID authentication to combat robocalls, as mandated by the FCC. Providers must implement digital certificates and attestations (A/B/C levels) for IP networks, with recent 2025 updates emphasizing third-party controls and trust anchors.

Key FCC Mandates

  • TRACED Act (2019): Requires all voice service providers (VSPs) to authenticate caller ID via STIR/SHAKEN to prevent spoofing.

  • Implementation Deadlines:

    • Large providers: June 30, 2021 (IP networks).

    • Small VSPs (≤100K lines): June 30, 2024.

    • Robocall Mitigation Plan Update: June 20, 2025 (certify full/partial implementation).

  • Eighth Report and Order (2025): "Third Party Rule" deadline September 18, 2025—providers must use their own certificates for signing, not third-party ones; update plans accordingly.

  • Call Authentication Trust Anchor (August 19, 2025): Providers must obtain Service Provider Code (SPC) tokens and digital certificates; adhere to attestation standards.

  • Call Branding FNPRM (October 7, 2025): Proposed rules for displaying "Spoofed" labels on unauthenticated calls; monitor for final adoption.

  • Attestation Levels: A (full verification), B (partial), C (gateway)—assign based on call origin knowledge.

  • Enforcement: Non-compliance risks fines, USF obligations, or call blocking; report illegal robocalls within 90 days.

Step-by-Step Application Process

  1. Obtain FCC Registration Number (FRN): Register your entity at fcc.gov/frn (free, 1-2 days; requires EIN/address).

  2. File Robocall Mitigation Plan in RMD: Certify STIR/SHAKEN implementation at fcc.gov/robocall-mitigation-database (annual; include plan for blocking spoofed calls). Update by June 20, 2025.

  3. Get Service Provider Code (SPC) Token: Apply via iconectiv.com/sti-pa (~$500 initial, $250 annual; 5-10 days).

  4. Secure Digital Certificates from STI-CA: Submit CSR to approved authorities (e.g., iconectiv, TransNexus; $1-5/certificate; 1-3 days).

  5. Implement in Network: Integrate certificates into SIP headers for attestation; test with STI-PA tools. For Third Party Rule: Use own certificates by September 18, 2025.

  6. Ongoing Renewal: Annual SPC/certificate updates; monitor RMD status.

Robocall Mitigation Strategies

  • Certify RMD plan with STIR/SHAKEN rollout.

  • Use Do Not Originate (DNO) lists to block known bad traffic.

  • Deploy AI/analytics for anomaly detection (e.g., high-volume calls).

  • Report illegal calls to FCC within 90 days.
