A buyer inquires on a business-for-sale listing at 9 p.m. By the time you call back the next afternoon, they've talked to another broker.
That's the case for AI calling your leads. It dials in seconds, it doesn't forget to follow up, and it never has an off day.
AI can already help you get ready for a call. Research, talking points, notes afterward. That work happens inside your business, and it gets its own post.
But should AI be the one making the call? Should it be the voice your lead hears?
That is AI that talks to the client for the broker, in its most exposed form. On a text or an email, you read the message before it goes out. On a live call, nobody reads anything first. The conversation happens in real time, and all you get afterward is a recording.
To answer that, you have to go back to February 2024. What follows is what I found when I went looking, with the sources named so you can check them yourself.
Did You Hear What Happened in February 2024?
In a ruling adopted on February 2, 2024 and released on February 8, the FCC looked at AI voices on phone calls and ruled that they count as "artificial or prerecorded voice" under the Telephone Consumer Protection Act (TCPA). The ruling also closed the door on one tempting argument. The TCPA gives no "carve out" for technology that claims to be the equivalent of a live agent. Sounding human doesn't change what it is.
As the ruling describes it, these calls need the prior express consent of the called party. If the call is telemarketing, that consent has to be in writing. Footnote 13 of the ruling puts it plainly: "If these robocalls introduce an advertisement or contain telemarketing, the Commission's rules require that the caller obtain the prior express written consent of the called party."
That matters for brokers, because outreach to a list is telemarketing. The general rule is consent. The rule for the calls you would actually make is written consent.
The ruling adds two more requirements. The message must state clearly, at the beginning, the identity of the business or person responsible for initiating the call. And any message that introduces an advertisement or constitutes telemarketing must also offer opt-out methods for the called party to stop the calls.
Marketing calls carry a higher bar. The FCC's rule has required prior express written consent for telemarketing calls with artificial or prerecorded voices. In February 2026, the Fifth Circuit (Texas, Louisiana, Mississippi) held in Bradford v. Sovereign Pest Control that the statute only requires consent, which can be oral or written. Other courts may keep applying the FCC's written-consent rule, and state laws still apply. So written consent still looks like the safer standard.
And Then the FTC Weighed In
The FTC enforces its own Telemarketing Sales Rule (TSR). As the FTC describes it, that rule prohibits calls using prerecorded messages whether or not the number is on the Do Not Call Registry. In March 2024, the FTC said it "affirms the TSR's prohibitions on robocalls using voice cloning technology." That language is about voice cloning.
The same 2024 rule matters for brokers because it reaches business calls. From what I read, the TSR long exempted most business-to-business calls, and the final rule narrowed that exemption so B2B calls must comply with the ban on false and misleading statements. The exemption also covers calls to induce a sale to a business, not calls to individuals employed by it.
Is There a Difference Between the Business and the Owner?
This is an ultra-relevant question because prospecting calls go to owners.
Experts and providers in this space seem to agree that the line matters more than the entity. The technology rules, the ones covering automated dialing and artificial or prerecorded voices, are described as applying to a cell phone whether or not the number is used for business, and B2B is described as a common misconception rather than a blanket exemption. The Do Not Call rules run the other way: they are described as covering residential numbers, which include cell phones but not business landlines. And in Miholich v. Senior Life Insurance Company (S.D. Cal., 2022), a number used for both business and personal purposes was reported to be treated as residential, with the court also noting that calling a residential number while believing it to be a business number still violates the statute.
For a broker that collapses into something simple. Most owners run their business from their own cell phone. Call that number and you are, in practice, calling the person.
How Vendors Talk About Risk
AI calling vendors have their own incentive here: say the risk plainly, and a buyer who sets things up right has reason to trust the product. Retell AI, one such vendor, puts it this way on statutory damages: $500 to $1,500 per call with no aggregate cap, and "Class-action exposure is the bigger risk, not the FCC."
On who carries that exposure, Retell says:
The entity on whose behalf the calls are made bears liability, regardless of which downstream vendor pressed dial.Retell AI
In plain terms, that is a vendor telling you: if you hire us to make the calls and something about a call breaks the rules, the vendor is not who gets sued. You are, because the calls go out in your name and on your behalf. That is how Retell frames its own exposure, and other vendors in this space tend to say something similar, because the underlying statute does not name the dialer. Treat it as the vendor's own interpretation of where it stands, not as a ruling on where you stand.
Then There Are the States
Federal law is not the whole story.
Florida's telephone solicitation law, as I read it, prohibits an unsolicited telephonic sales call that involves an automated system for the selection and dialing of telephone numbers, or the playing of a recorded message, without the called party's prior express written consent. It also lets an aggrieved called party sue, for actual damages or $500, whichever is greater, and up to triple that for a willful or knowing violation. Texas SB 140, as I read it, took effect on September 1, 2025 and extended that state's telephone solicitation law to text messages, adding a private right of action.
Several states are also adding AI-specific rules, such as disclosure at the start of a call. Not all states agree, so make sure you do research to understand the implications in the state.
Wait, Didn't They Fill Out a Form?
Not automatically.
Someone who filled out a valuation form or inquired on a listing is a warm lead. That doesn't mean they agreed to be called by an AI voice. What they agreed to depends on what your form said when they submitted it. Retell's read is that a form submission supports follow-up on that specific inquiry, but not unrelated marketing. Whether a call to a buyer about a listing counts as marketing at all is an open question for your attorney.
The Fifth Circuit case is a useful contrast. There, the customer gave his number and said it could be used to contact him, and that counted as consent. That holds in that circuit.
So the first question for any list is "what did they agree to, and can I prove it?"
Now, About That Cold List
Retell's FAQ says cold dialing without documented consent exposes you to per-call damages, and that "AI cold calling" should mean outreach to consented leads. A purchased list of business owners has no documented consent.
For owner prospecting, the line type matters. Whether the rules differ between a business landline and the personal line of the business owner, you would have to verify. Just remember: most businesses operate using their own personal cell phones.
Buyers and Sellers Don't Get the Same Answer
Buyers who inquired on a listing. Speed is the service, so a fast call can fit. The strongest case is a buyer who asked for information, with documented consent covering this kind of call, and a call limited to confirming interest and gathering qualifying details.
Sellers. The contact itself is what they came for. A seller who hears an AI voice from a firm they were considering trusting with their business learns something about how the rest of the process will go. A call can also land on a business line or a shared phone, which adds a confidentiality risk. Keep sellers out of this.
If a seller reaches out and they do encounter an AI answering the phone, make sure that you frame it as trying to be the most helpful in getting them connected with the right person, or treat it like a smart answering machine.
Before You Turn It On, Ask
- Do I have documented consent for this person, for this kind of call? If you can't produce the record, you don't have it.
- Does the call identify my business and offer an opt-out?
- Is this a buyer or a seller? If a seller, stop.
- What is the AI allowed to say and know? It only knows what you gave it.
- Who listens to the recordings, and how often? There's no approval step during the call, so review is your only check.
Who hears it first? The lead. Can anyone stop it mid-call? No. That's why the work moves to the front: consent, scope, and a narrow job.
General information, not legal advice. Talk to an attorney before you build on any of it.
