AI voice agents can answer calls, return missed calls and follow up with leads. They also sit inside one of the most litigated areas of US consumer law: the Telephone Consumer Protection Act (TCPA). Before you let an AI agent place outbound calls, it helps to understand the basic rules.
This article is general information, not legal advice. Rules change, and the details depend on your business, your call types and the states you call into. Please work with qualified counsel before launching outbound calling.
What the TCPA is
The TCPA is a federal law passed in 1991 to limit unwanted telemarketing and automated calls. The Federal Communications Commission (FCC) writes and interprets the rules under it. Among other things, the TCPA and FCC rules restrict:
- Calls made with an “artificial or prerecorded voice”
- Calls made with certain automated dialing equipment
- Telemarketing calls to numbers on the National Do Not Call Registry
- Calls outside permitted hours
The law allows private lawsuits with statutory damages per violation, which is why TCPA class actions are common.
The FCC’s February 2024 ruling on AI voices
In February 2024, the FCC issued a declaratory ruling confirming that calls using AI-generated voices, including voice cloning, fall under the TCPA’s restrictions on “artificial” voices. In plain terms: an AI voice is treated like a prerecorded or artificial voice for TCPA purposes.
That matters because artificial-voice calls carry stricter consent requirements than calls placed by a live person dialing manually. Many businesses assumed a conversational AI agent was more like a live caller. The FCC made clear that it is not, at least for this purpose.
Consent: the core question
For calls that use an artificial or AI voice, the general framework looks like this:
| Call type | General consent expectation |
|---|---|
| Informational call to a mobile number (for example, an appointment reminder) | Prior express consent |
| Telemarketing or advertising call to a mobile number | Prior express written consent |
| Telemarketing or advertising call to a residential landline | Prior express written consent, with limited exceptions |
| Emergency calls | Generally exempt |
Prior express written consent usually means a signed agreement (electronic signatures can qualify) that clearly authorizes the business to deliver marketing calls using an artificial or prerecorded voice to a specific number, and that makes clear consent is not a condition of purchase.
A few practical implications:
- A lead form that collects a phone number is not automatically consent to AI marketing calls. The consent language matters.
- Consent should identify your business specifically.
- Keep records: the exact wording, time, source page and the number provided.
Inbound vs. outbound calls
When a customer calls you and an AI receptionist answers, the TCPA’s outbound calling restrictions are generally not the main concern. The bigger questions there are disclosure, call recording consent and accurate information.
Outbound is different. If your AI agent calls leads, past customers or anyone else, consent and call purpose become central. A returned call to someone who just asked you to call them back is a very different situation from a cold marketing call.
Disclosure and identification
FCC rules require artificial or prerecorded voice messages to identify the business responsible at the beginning of the call and to provide a phone number during or after the message. For telemarketing calls using an artificial voice, an automated opt-out mechanism is also required.
Beyond the legal minimum, honest disclosure is good practice. We recommend that every AI agent:
- States early in the call that it is an AI assistant
- Names the business it represents
- Offers a way to reach a person
- Ends the call politely if the person asks not to be contacted, and records the request
Opt-outs and Do Not Call
Your system should:
- Honor do-not-call requests across every channel, including texts and human callers
- Check marketing calls against the National Do Not Call Registry and your internal list
- Respect calling-hour limits based on the recipient’s local time
- Stop all automated outreach to a number once the person revokes consent
State laws add more rules
Several states have their own telemarketing laws, often called “mini-TCPAs.” Some, such as Florida’s Telephone Solicitation Act, add their own consent definitions, calling hours, call-frequency limits or private rights of action. Other states regulate call recording, requiring consent from all parties. Some have also passed laws addressing AI disclosure or synthetic voices.
Because these rules vary and change, map out which states you call into and review them with counsel.
A practical pre-launch checklist
- Counsel has reviewed your outbound call types and consent language
- Each call type is classified as informational or marketing
- Consent wording names your business and covers AI or artificial-voice calls where needed
- Consent records are stored with time, source and wording
- The agent discloses it is AI and names your business at the start
- A callback number and opt-out path are provided on every call
- Opt-outs sync to your CRM and stop all channels
- Do Not Call registry scrubbing is in place for marketing calls
- Calling hours are enforced by recipient time zone
- State-specific rules are documented for the states you call
- Call recording disclosures meet the strictest applicable state rules
A hypothetical example
Consider a dental practice that wants an AI agent to call patients who requested a callback through the website. The callback request form includes clear language that the practice may call using an AI assistant. The agent introduces itself as the practice’s AI assistant, confirms the request and books a visit. If the patient says “please do not call me again,” the request is logged and every channel stops. That structure is easier to defend than an agent that dials an old list with unclear consent.
FAQ
Does the TCPA apply if a human supervises the AI agent?
Supervision alone does not change the fact that the voice the caller hears is AI-generated. Under the FCC’s 2024 ruling, AI-generated voices are treated as artificial voices, so the related consent rules apply. Ask counsel how your specific setup is classified.
Can an AI agent return a missed call from a customer?
Returning a call someone just placed to you is generally lower risk than unsolicited outreach, but the content and purpose of the call still matter. Keep the callback informational and relevant to their inquiry, and confirm the approach with counsel.
Do Canadian rules work the same way?
No. Canada has its own framework, including the CRTC’s Unsolicited Telecommunications Rules and the National Do Not Call List, plus CASL for electronic messages. Businesses calling into both countries need to plan for both.
