Control

An AI or artificial-voice outbound call is placed without a recorded prior express consent of the called party (written, for telemarketing)

An AI voice agent or text-to-speech dialer places an outbound call only after checking, for the number it is about to call, a stored prior express consent of the called party; for a call that introduces an advertisement or is telemarketing, the stored consent is a signed written agreement naming the seller and the number.

None of the 1 rule has been reviewed by a lawyer; no TwinEthos rule has been legally reviewed yet. Treat each as research to check against the official text; it is not legal advice. Open questions for counsel on them: 1.
Audit standard
1 of 1 rule audit-grade. The audit standard is TwinEthos's own quality bar for provenance, dates, applicability, detectors, fixtures, remediation and licences; it is not a legal review.
Detectors
1 detector, all experimental: written from the rule's text and not yet measured for precision on real code, so treat a hit as a lead to verify. Each provision lists its detectors' known limits.

The guard to add

Check a stored prior express consent (written, for telemarketing) for the number before the voice agent places any outbound call.

Before the call-placement API (Twilio calls.create, Vonage create_call, Telnyx, Retell create_phone_call, Vapi calls.create, Bland /v1/calls, ElevenLabs outbound_call, LiveKit create_sip_participant), look up the called number in a consent store and refuse to dial unless a current consent exists: prior express consent for an informational call, and, for a call that includes or introduces an advertisement or is telemarketing, a signed written agreement (electronic signatures count) that names the seller and the number and says consent is not a condition of purchase. Revocations set the record inactive at once. Emergency and exempt calls carry an explicit, logged reason instead of a consent id.

Where it goes: 1 application source code, 2 data models, 6 API calls and integrations, 15 agent action surface.

What reviewers look for: a consent lookup (has_tcpa_consent, consent_record, prior_express_written_consent) on the number immediately before every outbound-call API; the call purpose (informational or telemarketing) decides which consent is required; no batch dialer that loops over a lead list without the check; the consent id or exemption written to the call log.

Example (Python + Twilio + AI voice), before:

for lead in leads:
    client.calls.create(to=lead.phone, from_=FROM, url=VOICE_AGENT_TWIML)

After:

for lead in leads:
    consent = consents.prior_express_consent(lead.phone, purpose='telemarketing')
    if not consent or not consent.written:
        continue  # no prior express written consent: do not dial
    call = client.calls.create(to=lead.phone, from_=FROM, url=VOICE_AGENT_TWIML)
    call_log.record(call.sid, consent_id=consent.id)

Engineering guidance, not legal advice. Each provision below may add its own details (a cadence, a deadline, a required notice element): open it for those.
