STIR/SHAKEN
STIR/SHAKEN is the FCC-mandated caller ID authentication framework for US telephone networks — requiring carriers to verify and label calls as A (verified), B (partial), or C (unverified) — directly affecting MCA dialer call connect rates as carriers increasingly block or label unverified traffic as 'spam likely.'
Why This Matters
STIR/SHAKEN deployment has fundamentally reshaped MCA dialing economics. Outbound calls from VoIP providers without proper STIR/SHAKEN attestation increasingly arrive labeled 'Spam Likely' or 'Scam Likely' on merchant cell phones — collapsing connect rates from 30%+ to under 10%. MCA shops must work with carriers and dialer providers offering A-attestation (verified caller) and Branded Caller ID (logo and company name display). Smaller VoIP providers without proper attestation infrastructure are increasingly unviable for MCA dialing at scale.
Frequently Asked Questions
Frequently Asked Questions
How does STIR/SHAKEN affect MCA call connect rates?
Calls without A-attestation increasingly arrive as 'Spam Likely' — collapsing connect rates by 50–80%. Calls with A-attestation maintain normal connect rates. STIR/SHAKEN compliance is now table-stakes infrastructure for MCA dialing operations.
Can I get A-attestation for my MCA dialer?
Requires partnership with carriers offering A-attestation services and verifiable business identity registration. Major dialer providers (Five9, Genesys, RingCentral, Twilio) offer integrated A-attestation paths. Setup typically takes 30–60 days.
