TCPA AI lead follow-up: which step needs which consent

TCPA AI lead follow-up, step by step: an AI answering a lead makes no call, but the AI callback and drip texts need consent the lead may not have given.

Published: 2026-09-24 · Author: Ahmed Heshmat · 10 min read

In short: For TCPA AI lead follow-up, the first question at every step is who dialled. An AI answering a call the lead placed makes no call, so the Telephone Consumer Protection Act's consent rules do not reach it; the callback, the reminder text and the drip are calls the business makes, and the FCC treats texts as calls. Since the FCC's February 8, 2024 ruling, an AI voice is an "artificial" voice, so an AI callback to a mobile needs the lead's prior express consent, and prior express written consent if it markets anything. Solicitations run from 8 a.m. to 9 p.m. in the lead's time zone (8 p.m. in Massachusetts), a STOP must be honoured within 10 business days, and the rule that one STOP ends every unrelated robocall and robotext is waived until at least January 31, 2027.

Key takeaways

The FCC's AI ruling (FCC 24-17, para 9) applies to "any AI technology that initiates any outbound telephone call." Answering a lead who rang in is outside it.
A number left on an inbound call is permission to be called back about that request. It is not the signed agreement 47 CFR 64.1200(f)(9) requires before an AI voice or an autodialer delivers marketing, but the agent can collect that agreement on the same call: the FCC accepts a voice recording as a signature under the E-SIGN Act.
"Telemarketing" in the rules covers encouraging "the purchase or rental of" property, so a follow-up pushing a showing or a lease is marketing.
Any reasonable opt-out counts, including a reply of "stop", "quit", "end", "revoke", "opt out", "cancel" or "unsubscribe", and it must be honoured within 10 business days (64.1200(a)(10)).
The one-to-one consent rule never took effect; the Eleventh Circuit vacated it on January 24, 2025. What a brokerage needs for its own leads is unchanged.

The answer is outside the rule, the follow-up is inside it

47 U.S.C. 227(b)(1) makes it unlawful "to make any call" with an autodialer or an artificial or prerecorded voice without the called party's prior express consent, and the FCC's rules say "initiate." Both words describe the business dialling out. When a buyer rings a brokerage at 7pm and an AI agent picks up, the buyer made the call, and nothing in section 227(b) is engaged by the answer.

Most of what a search returns is about outbound calling to bought lists, as if the AI receptionist and the AI dialler were one product. Here is an ordinary lead flow.

|---|---|---|---|---|

The hours apply to "telephone solicitation" (64.1200(c)(1)), a call encouraging a purchase or rental. A reminder that only confirms a time the lead booked is not one.

What an AI voice changes

The February 2024 declaratory ruling, released February 8, confirmed that the TCPA's restrictions on an "artificial or prerecorded voice" encompass "current AI technologies that generate human voices." Everything the rules already demanded of a prerecorded message now applies to a conversational agent that dials out.

That means prior express consent to reach a mobile number (64.1200(a)(1)(iii)), and prior express written consent if the call "includes or introduces an advertisement or constitutes telemarketing" ((a)(2)), to a landline as well ((a)(3)). The message has to open with the business's registered name, give a callback number, and, when it markets, offer an automated opt-out within two seconds of that identification ((b)(1) to (b)(3)).

The autodialer question does not rescue an AI call. Facebook v. Duguid (2021) narrowed the autodialer definition to equipment using a random or sequential number generator to store or produce numbers. The artificial-voice rule never depended on the dialler.

Texts are calls

The FCC has treated a text to a mobile as a call since its 2003 order, which said the prohibition "encompasses both voice calls and text calls to wireless numbers" (para 165). The do-not-call rules now say it too: 64.1200(e) applies them to "telephone solicitations or telemarketing calls or text messages to wireless telephone numbers," wording from a December 2023 order that codified the registry's protection of texts, effective March 26, 2024.

After Duguid, many texting platforms are not autodialers. That can take a text outside the consent rule in section 227(b), never outside the do-not-call rules in 227(c): a drip text pushing a showing to a registered number is a solicitation whatever sent it.

What a phone call or a web form gives you

The FCC's reading of prior express consent goes back to 1992: "persons who knowingly release their phone numbers have in effect given their invitation or permission to be called at the number which they have given, absent instructions to the contrary," restated in a 2008 ruling (para 9) that tied the consent to the purpose the number was given for. A lead who leaves a number about a listing has agreed to hear back about that listing.

Prior express written consent is a different document. Under 64.1200(f)(9) it is an agreement bearing the lead's signature, electronic ones included, that authorizes the seller to deliver telemarketing by autodialer or artificial voice to a named number, with a clear disclosure that signing is not a condition of buying anything. A web form built for it can carry that, and so can the call itself. The FCC's 2012 order adopting the rule (para 34) accepts consent obtained under the E-SIGN Act, "including permission obtained via an email, website form, text message, telephone keypress, or voice recording." A bare "sure, text me" still falls short, because it carries none of the disclosures. What works is the agent reading them out (the number, what will be sent and by what means, and that agreeing is not a condition of renting or buying), then recording a clear yes and storing it with the call. The Ontario version of the same step is in the CASL post, where the CRTC accepts oral consent backed by a complete recording.

On one Toronto brokerage line we run, 1,190 answered calls over 102 days, 41.0% of callers were other realtors and 92.8% of them left a callback number, and 41.7% of all callers asked for a named person (the full breakdown). After-hours callers on that line left a number 70.7% of the time, daytime callers 72.5%. Most brokerage follow-up starts from a number volunteered about one request, which is narrower consent than a sales sequence needs. The request covers the callback. Listing alerts sent by an AI voice or an autodialer need the written agreement, collected before the first one goes out, and any listing text still answers to the do-not-call rules.

Quiet hours and the do-not-call lists

A solicitation may not reach a residential subscriber before 8 a.m. or after 9 p.m. local time, or a number on the national registry (64.1200(c)). Two exclusions in (f)(15) matter for a brokerage: a call made with the person's "prior express invitation or permission," and an established business relationship, which (f)(5) sets at three months after an inquiry and 18 months after a transaction. The brokerage's own list, under (d), needs a written policy, and a request on it is honoured within 10 business days and kept five years. Under 227(b)(3) a person can recover actual loss or $500 per unlawful robocall or robotext, whichever is greater. Under 227(c)(5), someone who gets more than one call in breach of the do-not-call rules within 12 months, by or on behalf of the same business, can recover actual loss or up to $500 per violation, whichever is greater. A court can triple either award for a willful or knowing violation.

Revocation, and the date summaries get wrong

The consent-revocation rules took effect on April 11, 2025. The seven words above revoke per se, any reply a reasonable person would read as stop counts, and no single opt-out channel may be made exclusive. One confirmation text is allowed, presumed fine within five minutes, with no marketing in it.

One piece is not in force: a stop sent in reply to one type of message ending every unrelated robocall and robotext from the same business. The FCC waived it to April 11, 2026, then on January 6, 2026 extended the waiver to January 31, 2027 while it reconsiders. Pages written before January 2026 still give April 11, 2026. We build as if it were live, because a lead who typed STOP on a showing reminder will not see the distinction.

The one-to-one rule is gone, and your own leads were never its target

The FCC's 2023 order would have made written consent name one seller at a time, aimed at comparison-shopping sites. It never took effect: on January 24, 2025 the FCC postponed it and the Eleventh Circuit vacated it in Insurance Marketing Coalition v. FCC as conflicting with "the ordinary statutory meaning of 'prior express consent.'" The text left the rules on August 29, 2025.

A brokerage's own form always named one seller, itself, so nothing loosened for it. Since McLaughlin Chiropractic v. McKesson (June 20, 2025), district courts read the TCPA for themselves, "affording appropriate respect to the agency's interpretation." The plain words "artificial voice" already fit a synthesized one, so we would not build on a court disagreeing with the FCC.

What Massachusetts adds

M.G.L. c. 159C s. 3 bars unsolicited telephonic sales calls between 8:00 p.m. and 8:00 a.m., to numbers on the state's no sales solicitation listing (s. 7 folds in the national registry), and "by use of a recorded message device." A call "in response to an express written or verbal request of the consumer" is not unsolicited (s. 1), and neither is one to a customer of the past 24 months, unless that customer has told the caller to stop. Within the first minute of a sales call, and before any talk of payment, the caller has to give the purpose of the call, the telemarketer's name, the seller's name and a full description of what is offered (s. 5A). The Attorney General can seek up to $5,000 per knowing violation, and a consumer who gets more than one unlawful sales call in 12 months from the same business can recover actual loss or up to $5,000 for a knowing violation, whichever is greater (s. 8).

Section 1 defines neither a recorded message device nor whether a text is a sales call, and we would not build on either gap. The practical change is the clock: solicitations stop at 8 p.m. Hence the design rule on our Boston page: consent captured before the first text goes out, and STOP handled on every thread.

The same flow in Ontario

We build this flow under CASL in Ontario, and it does not cross the border unchanged.

| | Ontario | United States and Massachusetts |

|---|---|---|

| Answering an inbound call | Not a message CASL covers | No call made by the business |

| A text replying to that inquiry | Exempt from the consent rule (SOR/2013-221 s.3(b)) | A call the business makes; the consent needed depends on the technology and the purpose |

| Inquiry window | Implied consent for messages, six months | Established business relationship, three months, for do-not-call purposes only |

| AI calling out | CRTC asked in June 2026 whether it is an automated dialer; no answer yet | Artificial voice since February 2024 |

| Solicitation hours | 9:00 a.m. to 9:30 p.m. weekdays, 10 a.m. to 6 p.m. weekends | 8 a.m. to 9 p.m. federally, to 8 p.m. in Massachusetts |

| Opt-out deadline | 10 business days for messages, 14 days for a do-not-call request | 10 business days for both |

The Ontario column reads off CASL, the CRTC's telemarketing rules and the CRTC's June 2026 consultation. The inquiry window is the trap: an Ontario flow texting listings for six months on an inquiry needs signed written consent in Massachusetts once it runs on an autodialer or an AI voice. The intake side is on AI lead intake for brokerages, and the CRM consent fields on Follow Up Boss automation.

What we checked

We read every source linked above on September 24, 2026, the eCFR as current to September 22. Recording rules for the same calls are in our Massachusetts call recording post.

This is an operator's reading, not legal advice. The voice agent we run answers inbound calls on one Toronto brokerage line. We run nothing in the United States yet, so this is the rule set we would build a Massachusetts flow to.

Frequently asked questions

Does the TCPA apply to an AI receptionist answering calls?

It does not apply to the answering. The robocall rules cover a business that makes or initiates a call, and the FCC's 2024 AI ruling speaks of AI that "initiates any outbound telephone call." When a lead calls in, the lead made the call. The rules start with the callback and the texts.

Can a real estate agent text a lead who called in?

Yes, about what the lead asked, since a number given on a call is permission to be contacted about that request. Listing texts sent through an autodialer need prior express written consent, which the agent can collect on that same call, and a solicitation to a registered number needs an exclusion such as an inquiry in the past three months.

Do AI voice calls need written consent?

For marketing, yes. Since February 8, 2024 an AI voice counts as an artificial voice, so an AI call marketing a listing or a showing needs the lead's signed prior express written consent. An informational AI call to a mobile needs prior express consent.

Can an AI agent collect TCPA written consent over the phone?

Yes, if it is done properly. The FCC's 2012 order accepts consent obtained under the E-SIGN Act, including by voice recording. The agent reads the disclosures the rule requires (the number, that marketing calls or texts will come by automated means, and that agreeing is not a condition of renting or buying), records a clear yes, and keeps the recording with the lead. A casual "sure, text me" without those disclosures is not written consent.

What are the calling hours for real estate solicitations in Massachusetts?

Federal rules allow solicitations from 8 a.m. to 9 p.m. local time. Massachusetts bars unsolicited telephonic sales calls from 8:00 p.m. to 8:00 a.m., so a Massachusetts brokerage stops at 8 p.m. A callback the consumer asked for is not unsolicited.

When does the TCPA revoke-all rule take effect?

Not before January 31, 2027. An FCC order of January 6, 2026 (DA 26-12) extended the waiver to that date while the FCC considers changing the rule, so the date can move again. The rest of the revocation rule has applied since April 11, 2025: any reasonable opt-out counts, and it must be honoured within 10 business days.
