This page is a practical orientation, not legal advice. Telemarketing and robocall laws vary by jurisdiction and change over time — consult your counsel about your specific calling program.
Before an organization first places outbound calls through ThunderPhone (starting a campaign, or calling POST /v1/call), an organization admin confirms once that the organization’s outbound calling complies with applicable law. This page explains what that actually involves.

​
Calls to U.S. numbers: the TCPA

The Telephone Consumer Protection Act (TCPA) and the FCC’s implementing rules (47 CFR § 64.1200) govern automated outbound calling. The rules that most commonly matter for AI voice agents:
  • Consent. Calls that use an artificial, prerecorded, or AI-generated voice generally require the called party’s prior express consent — and for marketing calls, prior express written consent. Consent must be obtained before the call and can be revoked at any time.
  • Identification. The call must identify who is calling, and provide a contact number.
  • Do-not-call. Marketing calls must honor the National Do-Not-Call Registry and your own internal do-not-call list; opt-out requests must be honored promptly.
  • Calling windows. Marketing calls are restricted to 8 a.m.–9 p.m. in the called party’s local time (ThunderPhone campaigns let you set calling windows).
  • State laws. Several states layer their own “mini-TCPA” statutes on top (Florida and Oklahoma are frequently cited), sometimes with stricter consent or timing rules.
Statutory damages run 500–500–1,500 per call, which is why consent hygiene on your contact lists matters more than any other single thing.

​
Calls to other countries

Outside the U.S., the destination country’s rules apply — for example PECR/Ofcom rules in the UK, CRTC telemarketing rules and CASL in Canada, and ACMA rules in Australia. Requirements typically cover consent or opt-out registries, calling hours, and caller identification.

​
What the confirmation is

The dashboard asks an organization admin to confirm, once, that the organization takes responsibility for its outbound calls complying with these laws. It applies only to calls your agents originate — inbound calls and call transfers are never affected — and running campaigns are never interrupted by it. Organizations that existed before August 3, 2026 are not asked at all.
