Voice broadcasting is the automated delivery of a recorded or synthetic voice message to many phone numbers at once, used for alerts, reminders and notifications. It is legal when the people called have given the consent the destination country requires: in the United States, prerecorded calls are among the most regulated calls under the TCPA, and every other country has its own rules.
This guide gives a general overview as of 2026, based on FCC rules for the US. It is not legal advice; check the rules of each country you call.
Is voice broadcast legal?
In the US, the TCPA and FCC rules (47 CFR 64.1200) treat broadcast calls as calls using an "artificial or prerecorded voice":
| Broadcast type | US federal consent rule |
|---|---|
| Informational, to mobile numbers (reminders, service alerts) | Prior express consent |
| Telemarketing or advertising, to mobile or residential numbers | Prior express written consent |
| Emergency calls affecting health and safety | Exempt |
| Some non-marketing calls to residential lines | Limited exemptions with call caps and opt-out |
Messages must state the caller's identity at the start and give a phone number. Telemarketing broadcasts must offer an automated opt-out, and opt-outs must be honored within 10 business days. Calls go only between 8 a.m. and 9 p.m. local time, and numbers on the National Do Not Call Registry are off limits for telemarketing. Since February 2024, AI-generated voices count as artificial voices. More in are auto dialers legal.
Outside the US, rules differ by country. Many countries ban or tightly limit recorded marketing calls without consent, run do-not-call registers or apply data protection law to calling lists. Check each destination before you send.
How does a voice broadcasting service work?
- You upload a contact list, scrubbed against do-not-call lists, with proof of consent.
- You record a message or generate one with text to speech, and optionally add IVR options.
- The platform schedules calls in each contact's allowed hours and dials at a set CPS.
- Answering machine detection decides whether to play the live message or leave a voicemail.
- Reports show answered, voicemail, busy, failed and opt-out results.
What is voice broadcasting software used for?
- Emergency and safety alerts from schools, utilities and local authorities.
- Appointment and payment reminders to customers who agreed to receive them.
- Service outage and delivery notifications.
- Internal staff alerts and shift notices.
- Marketing campaigns, only with written consent where the law requires it.

What do voice broadcast campaigns need from VoIP routes?
Broadcasting sends many calls in bursts, most of them short, and carriers watch that pattern closely. Many routes do not accept it. You need:
- Routes that explicitly accept broadcast or dialer traffic. See dialer traffic on VoIP routes and VoIP traffic types.
- An agreed CPS limit and enough channels for the peak. See VoIP channels and CPS.
- Per second billing, because messages are short. See billing increments.
- Caller IDs you own, attested and registered, so calls are not labeled spam. See spam likely on business calls.
Expect KYC: suppliers ask for your company, use case, sample message and consent process, and they cut routes when undeclared broadcast traffic appears.
How to keep a voice broadcast compliant
- Keep consent records per number, with date and source.
- Identify your business at the start of the message.
- Offer an opt-out in the call and remove opt-outs across all lists.
- Respect calling hours by the contact's time zone.
- Keep campaigns, recordings and results for audits and disputes.

Frequently asked questions
Is voice broadcasting legal?
Voice broadcasting is legal when the calls follow the rules of the country called. In the US, prerecorded calls to mobile numbers need prior express consent, and prerecorded telemarketing needs prior express written consent, with identification and opt-out rules. Emergency alerts and some informational calls have exemptions. Other countries have their own rules, often stricter.
What is the difference between voice broadcasting and robocalls?
Technically they are the same: automated calls that play a recorded or synthetic message. Robocall is the common word, often used for unwanted calls, while voice broadcasting is the industry term for mass notification services. The legal treatment depends on consent and content, not on the name the sender uses.
What is IVR voice broadcast?
It is a broadcast call that adds an interactive menu after the message, such as press 1 to talk to an agent, press 2 to confirm or press 9 to opt out. It lets people respond without a live agent on every call. For US telemarketing broadcasts, an automated opt-out option is required by FCC rules.
Can I use an AI voice for voice broadcasting?
You can, but in the US the FCC ruled in February 2024 that AI-generated voices count as artificial voices under the TCPA. Broadcasts with AI voices therefore need the same consent as prerecorded calls. Cloning a real person's voice without permission can also break other laws. Rules elsewhere differ, so check each country.
