Voice broadcasting sends a prerecorded or automated message to many phone numbers at once. Used well, it delivers appointment reminders, emergency alerts, school closures and service outage notices quickly. Used carelessly, it becomes the robocall problem that US regulators, carriers and consumers are fighting hard against.
The rules are strict and the penalties can be serious, including statutory damages in private TCPA lawsuits that can add up quickly across large call volumes. This guide explains the main rules in plain English.
This article is general information, not legal advice. Talk to a lawyer before launching any automated or prerecorded calling campaign.
The key laws and regulators
- Telephone Consumer Protection Act (TCPA) and FCC rules: restrict calls made with autodialers or artificial or prerecorded voices, and establish the National Do Not Call protections.
- Telemarketing Sales Rule (TSR) enforced by the FTC: governs telemarketing, including robocall restrictions, Do Not Call, call abandonment and disclosure requirements.
- TRACED Act: strengthened enforcement against illegal robocalls and required caller ID authentication.
- State laws: many states add their own telemarketing rules, registration requirements and calling hour limits.
Consent rules in plain English
Informational prerecorded calls
Non-marketing prerecorded calls to mobile phones, such as appointment reminders or delivery notices, generally require the recipient's prior express consent. Giving your phone number to a business for a related purpose may establish consent for related calls in some circumstances, but the scope is limited.
Marketing prerecorded calls
Prerecorded or artificial voice telemarketing calls to residential lines and mobile phones generally require prior express written consent: a signed agreement, which can be electronic, that clearly authorises the seller to deliver telemarketing calls using a prerecorded or artificial voice, identifies the number and states that consent is not a condition of purchase.
Emergency calls
Calls made for emergency purposes affecting health and safety are treated differently, but the exemption is narrow.
Revoking consent
Consumers can revoke consent through any reasonable means. Honour opt-out requests promptly and keep records.
AI-generated voices
In February 2024, the FCC issued a declaratory ruling confirming that calls using AI-generated or cloned voices count as calls using an "artificial" voice under the TCPA. That means the same consent rules apply to AI voice calls as to prerecorded calls. Several states have also introduced rules on AI in political and commercial calls.
Required disclosures and opt-outs
Prerecorded messages generally must identify the business responsible at the beginning of the message and provide a phone number. Prerecorded telemarketing messages must also offer an automated, interactive opt-out mechanism that the recipient can use during the call, such as pressing a key, and the opt-out must be processed.
Do Not Call and calling hours
- Telemarketing calls to numbers on the National Do Not Call Registry are restricted unless an exception applies, such as an established business relationship within the rules' time limits or the consumer's written permission.
- Businesses that telemarket must maintain an internal do-not-call list and honour requests.
- Telemarketing calls are restricted to between 8 am and 9 pm in the recipient's local time under federal rules, and some states set narrower windows.
- Telemarketers must transmit caller ID information.
STIR/SHAKEN and call labelling
The FCC requires most voice providers to implement STIR/SHAKEN caller ID authentication on IP networks, which helps carriers verify that calls really come from the number displayed. Carriers and analytics companies also label or block calls that look suspicious. Even legitimate calls can be labelled "Spam Likely" if numbers are new, call volumes spike or many recipients do not answer. Register your numbers with the major analytics providers where possible, keep volumes consistent and use clear branded caller ID.
Safe and useful use cases
- Appointment reminders for clinics and service businesses, with consent
- School and campus emergency alerts
- Utility outage and service interruption notices
- Pharmacy refill reminders with appropriate consent
- Payment reminders that follow debt collection rules where applicable
- Internal staff alerts and shift notifications
High-risk use cases
- Cold prerecorded sales calls to purchased lists
- AI voice calls without written consent
- "Ringless voicemail" campaigns without consent
- Calls with spoofed caller ID
- Political calls without understanding the specific rules that apply
IVR: the inbound side
An IVR (interactive voice response) system handles incoming calls with menus such as "Press 1 for sales". Inbound IVR is far less regulated than outbound robocalls, though call recording laws apply. Some states require all parties to consent to call recording, so announce recording at the start of the call.
Best practices for compliant voice campaigns
- Collect clear, documented consent, with written consent for marketing.
- Scrub telemarketing lists against the National Do Not Call Registry and your internal list.
- Respect federal and state calling hours in the recipient's time zone.
- Identify your business at the start of every message.
- Provide an easy opt-out and process it promptly.
- Use authenticated, consistent caller ID.
- Keep records of consent, calls and opt-outs.
- Review state laws for every state you call.
Voice vs text vs other channels
For many reminders, texting is cheaper and less intrusive, though it has its own TCPA and 10DLC requirements. Voice is valuable for urgent alerts, older audiences and messages that need a human tone. Many organisations use both. See our comparison of RCS, SMS and WhatsApp in the US.

Writing a good reminder message
Keep prerecorded messages short and clear. Start with who is calling, give the key information once, offer a simple action and repeat the most important detail at the end. For example: "Hello, this is Riverside Dental with a reminder of your appointment tomorrow, Tuesday, at 10:30 am. Press 1 to confirm, press 2 to reschedule, or press 9 to stop receiving these reminders. To speak to us, call 555-0100." Record in a warm, natural voice, or use high-quality text-to-speech for dynamic details such as dates and times, and test messages on real phones before sending widely.
Measuring voice campaigns
Track answer rates, completed listens, key presses, confirmation rates and opt-outs. For reminder campaigns, the most important measure is the reduction in no-shows or missed payments compared with before. Look at time-of-day patterns to choose the best calling windows within the permitted hours, and keep numbers healthy by monitoring for spam labels.
Choosing a voice provider
Ask any provider how it handles STIR/SHAKEN attestation, caller ID registration with analytics companies, opt-out processing, Do Not Call scrubbing, time-zone-aware scheduling and record retention. A provider that cannot answer these questions clearly may expose you to risk.
Vendor contracts and liability
Using a vendor does not remove your responsibility. Under the TCPA, the business on whose behalf calls are made can be liable for violations, so make sure your contract describes who obtains consent, who scrubs lists and who keeps records.
