FTC Telemarketing Sales Rule, B2B calls, and AI voice in 2024

Last updated 2026-07-09

What does the FTC Telemarketing Sales Rule actually cover?

The Telemarketing Sales Rule (TSR) is an FTC regulation under the Telemarketing and Consumer Fraud and Abuse Prevention Act of 1994 ^[1]. It sets baseline rules for outbound sales calls: when you can call, what you must disclose, what you cannot say, and what triggers liability. The FTC enforces it, not the FCC. That distinction matters, because the two agencies regulate overlapping but distinct slices of phone-based selling.

The TSR applies to "telemarketing," which the rule defines as a plan, program, or campaign to sell goods or services through interstate telephone calls ^[1]. That definition is broad. It catches most outbound sales operations, including B2B ones, as long as money is changing hands or a commercial transaction is the goal.

One thing teams get wrong: they treat the TSR and the TCPA as the same law. They aren't. The TCPA (47 U.S.C. § 227) is enforced by the FCC and through private lawsuits, and it has its own consent and autodialer rules. The two overlap on the Do Not Call list. But the TSR also governs disclosures, deceptive tactics, and now AI voice identification in ways the TCPA does not. You have to track both. Learn the basics of cold calling compliance in our cold calling overview.

What changed in the FTC's 2024 TSR amendments?

The FTC published its final 2024 TSR amendments in the Federal Register on March 7, 2024, with most provisions taking effect in August 2024 ^[2]. The rulemaking had been in progress since 2022. The final rule touched several areas, but the one generating the most compliance questions is the new AI-voice disclosure requirement.

Here is the core new text, quoted from the amended rule: the TSR now prohibits telemarketers from failing "to disclose promptly and in a clear and conspicuous manner" that the call uses "an artificial or prerecorded voice" ^[2]. "Promptly" means at the outset of the call. Not buried in minute three.

Other 2024 changes worth knowing:

• Expanded recordkeeping. Sellers and telemarketers must keep records that document compliance with the AI disclosure requirement, including call logs and scripts, for 24 months ^[2].
• Stronger prohibition on misrepresentation. The amendments made clear that impersonating a government agency or a real person using AI voice is an unfair or deceptive act, whether or not the caller made an express false statement ^[2].
• No blanket exemption for informational calls. Some teams assumed that "informational" AI calls (scheduling reminders, appointment confirmations) dodge the TSR. They don't, if those calls are part of a selling campaign ^[1].

The practical effect is blunt. If your outbound team uses any AI voice synthesis, voice cloning, or AI-generated robocall technology, you have to tell the person on the other end right away.

Are B2B calls exempt from the Telemarketing Sales Rule?

This is where small teams make expensive assumptions. The TSR has a B2B exemption, but it is much narrower than the TCPA's treatment of business calls.

Under 16 C.F.R. § 310.6(b)(7), the TSR exempts calls between a telemarketer and any business for the purpose of inducing the purchase of goods or services by that business ^[3]. Read that slowly. It exempts calls where the purchaser is a business entity buying for business use. Sell SaaS seats to a procurement manager and you're probably inside the exemption. Sell the same product to a sole proprietor on a personal cell phone in a home office, and you may not be.

The exemption does not cover:

• Calls to individuals who happen to work at a company but are being solicited as consumers.
• Calls to small businesses where the line between personal and business use is blurry.
• Any call that involves a prize promotion or charitable solicitation, even if the target is a business contact.

The 2024 amendments made the FTC's position on AI voice explicit. Even inside the B2B exemption, using AI-generated voice without disclosure can still be a deceptive or unfair practice under Section 5 of the FTC Act, which has no carve-out for business-to-business conduct ^[10]. The exemption reduces TSR procedural requirements. It does not immunize deception.

Here's the short version. The B2B exemption might remove your obligation to check the National DNC Registry for a covered B2B call. It does not remove your obligation to disclose AI voice. Treat those as two separate questions, always.

What exactly counts as an 'AI-generated voice' under the 2024 rule?

The amended TSR does not publish a technical spec with a list of approved or banned tools. It uses the phrase "artificial or prerecorded voice" ^[2], which is deliberately technology-neutral.

In its 2024 rulemaking commentary, the FTC signaled that this covers text-to-speech synthesis, voice cloning (where a model replicates a real person's voice), and fully synthetic AI voices generated by large language model systems. It also covers traditional prerecorded robocalls, which were already regulated. The 2024 additions specifically address the newer category: AI-cloned or AI-synthesized voices that sound indistinguishable from a live agent.

Human agents who use AI-generated talking points, scripts, or real-time coaching tools but speak in their own voice are not covered by this provision. The disclosure requirement attaches to the voice itself, not the back-end tools helping the human. If an AI generates the entire spoken content and the human just triggers playback, though, the FTC would almost certainly treat that as a prerecorded or AI voice call.

For AI cold calling tools specifically, the safe operating assumption is simple. If the voice the prospect hears was generated or substantially synthesized by a machine, disclose it. Do not let a vendor's marketing about "natural-sounding AI" talk you out of the disclosure.

How does the TSR AI disclosure requirement work in practice?

Simple in principle, occasionally awkward in execution. At the start of the call, before any sales pitch, the caller has to tell the prospect they are speaking with or hearing an artificial or prerecorded voice.

The FTC has not mandated script language, but the disclosure has to be clear and conspicuous. Something like: "This call uses an AI-generated voice. You're being contacted by [Company Name] about [product/service]." That works. What doesn't: burying the disclosure after a two-minute product intro, putting it only in a follow-up email, or having the AI say something fuzzy like "Hi, this is an automated system" and then launching into a pitch that sounds custom-written for the listener.

A few operational points:

1. Your call recording and logging system should capture the disclosure portion of every call so you can prove compliance during an FTC investigation. The 24-month record retention rule applies here ^[2]. 2. If a human dials and then hands off to an AI system mid-call, the disclosure obligation likely attaches when the AI voice takes over. The 2024 rule text doesn't settle this explicitly, but the spirit of the requirement points that way. 3. Your cold calling scripts and IVR flows need an audit against this requirement before deployment.

Teams using vendors for AI outreach should check their contracts. Under the TSR, both the seller and the telemarketer can be liable, and "my vendor handles compliance" is not a defense ^[1].

What are the TSR penalties, and how does the FTC actually enforce them?

Each TSR violation carries a civil penalty of up to $51,744 as of 2024 (the FTC adjusts this figure annually for inflation under 16 C.F.R. § 1.98) ^[4]. Each call is a separate violation. A campaign that makes 10,000 non-compliant AI calls without disclosure is not a $51,744 problem. It is a potential $517 million problem, before any state-level multipliers.

The FTC has pushed hard on AI-related enforcement around the 2024 amendments. In 2024, the Commission brought actions tied to AI impersonation and voice cloning, using both TSR and Section 5 FTC Act authority ^[5]. The agency does not need a consumer complaint to open an investigation. It can act on its own.

State attorneys general can enforce the TSR independently ^[1], and many have their own telemarketing statutes running alongside it. Florida has the Florida Telemarketing Act. Texas regulates telephone solicitations under its Business and Commerce Code. A TSR violation often trips state-level liability at the same time.

Here's the enforcement reality for a small team. The FTC tends to chase larger, systematic violators first, but it does go after small operations when the conduct is egregious or the harm is obvious. AI impersonation, especially making an AI sound like a real named person or a government official, is exactly the kind of thing that draws fast attention.

How does the TSR interact with the TCPA for B2B AI calls?

The TSR and the TCPA are parallel frameworks. They overlap a lot, but they are not duplicates ^[1][8]. For B2B AI calls, the gap between them is where teams get hurt.

The TCPA (47 U.S.C. § 227) bars using an autodialer or prerecorded voice to call a cell phone without prior express consent, with limited exceptions. Its B2B treatment is messy. The TCPA does not explicitly exempt B2B calls, but the FCC has read the statute to allow somewhat more flexibility for calls to business lines. The variable that decides everything is whether the number is a personal cell phone used for business or a dedicated business line.

The TSR, by contrast, has an explicit B2B exemption in the rule text (§ 310.6(b)(7)) ^[3]. But as noted above, it's narrower than most people think, and it does not cover AI voice deception.

Here is where they collide. Run a B2B AI voice campaign and you may need to satisfy both:

• TSR: disclose the AI voice at the start of every call, no matter whether the B2B exemption applies to other TSR provisions.
• TCPA: if you are calling cell phones (which is nearly every business contact in 2024), you need a lawful basis, which may require consent.

The FCC issued guidance in 2024 finding that AI voice synthesis meets the definition of "artificial or prerecorded voice" under 47 U.S.C. § 227(b)(1) ^[8]. That means TCPA consent requirements likely apply to AI voice B2B calls to cell phones, even where the TSR B2B exemption would otherwise cut your TSR obligations. Two layers, not one.

What B2B call scenarios are actually covered versus exempt under the TSR?

Let's get concrete. Here is how the analysis runs across common scenarios.

Scenario 1: AI voice call to a Fortune 500 procurement manager's desk phone to sell enterprise software. TSR B2B exemption likely applies for DNC and calling-hours provisions. AI voice disclosure is still required. TCPA risk is lower on a landline business line.

Scenario 2: AI voice call to a sole proprietor's personal cell phone listed on their business website. TSR B2B exemption is uncertain here; the person is both the business and the consumer. AI voice disclosure required. TCPA risk is high because it's a cell phone and likely needs consent.

Scenario 3: AI voice robocall to a purchased list of "small business owners" that includes many home-office consumers. TSR B2B exemption does not reliably apply when the list composition is uncertain. AI voice disclosure required. The FTC would likely see this as a consumer-facing campaign with weak protections.

Scenario 4: AI voice scheduling reminder to an existing B2B customer to confirm a sales meeting. If it's part of the selling campaign, the TSR may apply. If it's pure account management with no selling element, it may fall outside the TSR's "telemarketing" definition. AI voice disclosure is the safe move either way.

The safest posture: apply the AI voice disclosure on every call, universally, and treat the B2B exemption as covering only the calling-hours and DNC Registry provisions. Never the disclosure or anti-deception requirements.

What records do you need to keep for TSR compliance on AI B2B calls?

The 2024 TSR amendments reinforced existing recordkeeping rules and added new ones tied to AI use ^[2]. You have to keep the following for 24 months:

• Advertising and promotional materials, including scripts used in AI voice campaigns.
• Records of prize recipients, if applicable.
• Sales records, including the seller's identity, the goods or services sold, the date, and the amount.
• Employee and independent contractor records for anyone involved in telemarketing.
• Compliance procedures and call monitoring records.
• For AI voice specifically: documentation showing the AI voice disclosure was in the call flow, ideally call recordings or verified script audits.

The 24-month window is the FTC's standard. Some state laws require longer. If you operate in California, Texas, or Florida, check those state telemarketing statutes on their own terms.

A practical compliance kit should include a call script template with the AI disclosure at the top, a log format that captures call date, phone number, whether AI voice was used, and the disclosure confirmation, plus a quarterly audit checklist for your vendor's call flow. LeadCompliant's compliance kit has templates built around these exact requirements if you want a starting point to customize.

One hard rule: don't store recordings only on your AI vendor's platform. If the relationship ends or the vendor has a data incident, you need independent access to prove your compliance posture.

How should you rewrite your B2B call scripts and IVR flows to comply?

Your cold call script or IVR opening needs to do three things in the first ten seconds: identify the caller, disclose the AI voice, and give the prospect a clear path to opt out or reach a human.

A compliant opening might sound like: "This is an automated call using an AI-generated voice from [Company Name]. If you'd like to be removed from our call list, press 2 now. Otherwise, stay on the line to hear about [specific offer]."

What that script gets right:

• AI voice disclosed immediately.
• Company name given before any pitch.
• Opt-out offered up front (the TSR requires easy opt-out mechanisms for sales calls ^[1]).

What common scripts still botch:

• Opening with a human-sounding "Hey, is this John?" before disclosing the AI voice.
• Disclosing the AI voice only when the prospect asks.
• Offering opt-out only at the end, after the full pitch.

If you run a hybrid model where an AI qualifies the lead and then transfers to a human rep, the AI-stage script still has to carry the disclosure. When the human picks up, they don't need to re-disclose the prior AI interaction, but they should confirm who they are and what company they represent, per the TSR's caller ID requirements.

What should you do right now if your team runs B2B AI voice campaigns?

The August 2024 effective date for the 2024 TSR amendments has passed. If you've been running AI voice B2B campaigns without the disclosure, you're already out of compliance. Here is a practical remediation sequence.

First, audit every active AI voice call flow. Pull the opening script or recording for every campaign. Flag any that lack a clear AI voice disclosure in the first two sentences.

Second, contact your AI call vendor in writing and get confirmation that the disclosure language is on all active campaigns. Keep that correspondence. If the vendor can't confirm, pause the campaign.

Third, update your internal DNC procedures to flag any numbers where contacts have asked for no further contact. The TSR's DNC rules still apply to any TSR-covered B2B calls, and honoring opt-outs is non-negotiable ^[1].

Fourth, verify your recordkeeping captures call recordings or script version histories with timestamps. You want to show the FTC, if asked, exactly when your disclosure went live.

Fifth, run a legal review with outside counsel who knows FTC enforcement, not only TCPA litigators. The TSR and FTC Act enforcement posture differs from TCPA class action defense, and you want someone who knows the difference.

LeadCompliant's free TSR compliance checker can help you spot gaps in your script and call flow before the next campaign. It's a useful first pass, not a substitute for counsel, but it catches the most common mechanical failures fast.

Frequently asked questions

Does the FTC Telemarketing Sales Rule apply to all B2B calls?

Not entirely. The TSR has an explicit B2B exemption at 16 C.F.R. § 310.6(b)(7) that removes some obligations, like checking the National DNC Registry, for genuine business-to-business calls. But the exemption does not cover the 2024 AI voice disclosure requirement or the TSR's anti-deception provisions. If you're calling sole proprietors or mixed consumer/business lists, the exemption may not apply at all.

When did the 2024 FTC TSR AI call amendments take effect?

The FTC finalized the 2024 TSR amendments in March 2024 and published them in the Federal Register on March 7, 2024. The AI voice disclosure provisions took effect in August 2024. If your team ran AI voice B2B campaigns without disclosure before August 2024, the prior rule's general prohibition on deceptive practices still applied, so you weren't off the hook before the effective date either.

What exactly do you have to say to disclose an AI voice on a sales call?

The FTC has not prescribed exact script language, but the disclosure has to be clear, conspicuous, and at the outset of the call. Something like "This call uses an AI-generated voice from [Company Name]" satisfies the standard. It has to come before any pitch content. Hiding it at the end of the call or in fine print does not comply. Pair it with your company name and an opt-out mechanism for a complete compliant opening.

Is using a prerecorded human voice (not AI) still covered by the TSR?

Yes. The TSR has long covered "artificial or prerecorded voice" calls, which includes traditional prerecorded human voice messages. The 2024 amendments did not remove that existing coverage. They extended and clarified how the rule applies to AI-synthesized and AI-cloned voices specifically. Any prerecorded or AI voice used in telemarketing requires disclosure.

Can the FTC fine you for a single non-compliant AI call?

Technically yes. The TSR penalty is up to $51,744 per violation, and each call is a separate violation. The FTC tends to focus on systematic violators rather than one-off errors, but if your campaign made thousands of calls without disclosure, each is separately actionable. State attorneys general can add their own penalties on top of FTC enforcement.

Do you still need to check the National DNC Registry for B2B AI calls?

For calls that qualify under the TSR's B2B exemption (16 C.F.R. § 310.6(b)(7)), you are not required to check the National DNC Registry. But the exemption is narrow. Calls to sole proprietors, calls to cell phones used for personal and business purposes, and calls where the product is intended for personal use may not qualify. When in doubt, check the registry anyway. A registry subscription costs little next to enforcement exposure.

How does the FCC's 2024 AI voice ruling affect B2B callers on top of the FTC TSR?

The FCC issued guidance in 2024 finding that AI-synthesized voice meets the definition of artificial or prerecorded voice under the TCPA (47 U.S.C. § 227), which means TCPA consent requirements apply to AI voice calls to cell phones. The FTC TSR and FCC TCPA are separate frameworks, but both now cover AI voice. B2B callers using AI voice to reach cell phones need to satisfy both at once.

What records do I need to keep to prove TSR compliance for AI B2B calls?

The TSR requires 24 months of records including call scripts, promotional materials, sales records, and compliance procedures. For AI voice calls, you also need records showing the disclosure was in the call flow, such as call recordings or audited script logs with timestamps. Keep these records independently of your AI vendor's platform in case the vendor relationship ends or their records become unavailable.

My vendor says our AI call tool is compliant. Is that enough?

No. Under the TSR, both the seller and the telemarketer can be held liable for violations. Your vendor calling their tool compliant does not transfer your liability to them. You need to verify the actual call flow, get the compliance representations in writing, and audit the output yourself. FTC enforcement actions regularly name both the company running the campaign and the service provider if the provider had actual knowledge of the violations.

Are AI voice calls that only leave voicemails covered by the TSR?

Voicemail drops, often called ringless voicemails, are a contested area. The FTC has signaled that prerecorded messages left as voicemails as part of a selling campaign can fall within TSR coverage because they are part of the telemarketing plan. The FCC has similarly found ringless voicemails can implicate the TCPA. Treat voicemail drops with the same disclosure and consent care you'd apply to live-answer calls.

Does the TSR apply to outbound texts or only to calls?

The TSR, as currently written, covers telephone calls. It does not expressly cover SMS or text messages. The TCPA covers text messages separately. But the FTC has broad Section 5 FTC Act authority over deceptive practices in any medium, so AI-generated texts that impersonate humans or hide their nature could still draw FTC action even if the TSR text does not literally reach them.

What is the difference between the TSR and the TCPA for outbound sales teams?

The TSR is an FTC rule covering what you say and do on a sales call: disclosures, deceptive practices, DNC compliance, recordkeeping. The TCPA is an FCC statute covering how you reach someone: autodialer use, prerecorded voice calls to cell phones, and consent requirements. Both can apply to the same call. The TCPA allows private lawsuits; the TSR is enforced by the FTC and state AGs. You need to track both.

How do I know if my outbound campaign qualifies for the TSR's B2B exemption?

Ask three questions. Is the person you're calling buying on behalf of a business entity, not themselves personally? Is the product or service for business use, not personal use? Is the number a business line, not a personal cell phone used for mixed purposes? If all three answers are yes, the B2B exemption likely applies to DNC and calling-hours provisions. It never applies to the AI voice disclosure requirement or anti-deception provisions.
