Compliance

The checks Larynth runs on outbound calls, and what stays your responsibility.

Larynth’s checks help you follow calling rules. They do not make a call lawful on their own, and Larynth does not promise compliance. You are the caller. Your legal responsibility stays with you. Ask your own lawyer about your situation.

Checks before an outbound call

Every outbound call, from a campaign or from POST /v1/calls, goes through these gates before it dials:

Check	What it does
Verified business	The business behind the account is verified before it can place outbound calls. Unverified accounts can only receive calls.
Consent on file	The contact needs a consent record: how and when they opted in, and what they agreed to. No record, no call.
Do-Not-Call scrub	The number is checked against your Do-Not-Call list and the Larynth opt-out list.
Calling hours	The contact’s state and local time are checked. Outside the allowed window the call waits.
AI disclosure	The agent says it is an AI assistant at the start of the call and names the business it calls for.
Recording notice	Callers hear a recording notice.

Outbound calls to emergency numbers (911) are blocked.

When a call is refused

A refused call returns an error with a stable code that names the rule, for example dial.window.closed. When the refusal is about calling hours, the error includes retry_at, the next moment the call may be allowed.

GET /v1/compliance/decisions lists every pre-dial decision, with the rule, the result and the time. Use it to see why a contact was not dialed.

Consent

Record consent with POST /v1/compliance/consents. A record needs:

• the number (e164) and the kind: express or express_written
• when it was granted (granted_at) and how it was captured (source)
• evidence: an evidence_ref or evidence_text
• a scope: the whole account, or one campaign

Consent records are kept and cannot be deleted by you.

Opt-outs and Do-Not-Call

• POST /v1/compliance/revocations records that someone withdrew consent. The number is added to your internal Do-Not-Call list.
• POST /v1/compliance/dnc adds a number to your internal list directly.
• Larynth keeps its own opt-out list, fed by opt-outs on calls, and applies it to every account.
• The agent can end a call and record an opt-out with the opt_out tool.

What stays with you

• You follow the laws that apply to your calls.
• You bring your own Do-Not-Call registrations for outbound campaigns.
• You only call people who gave the consent your calls need.
• You tell your own staff that calls are recorded.
• You review the terms and the acceptable use policy for your situation.
