Top auto dialer tools with compliance safeguards (2026 guide)

Last updated 2026-07-09

What makes an auto dialer 'compliant' under TCPA?

Compliance is not a toggle. It is a set of behaviors that lower the odds a call triggers liability under the Telephone Consumer Protection Act, 47 U.S.C. § 227 ^[1]. The law restricts any 'automatic telephone dialing system,' or ATDS, from calling cell phones without prior express written consent. The FCC's One-to-One Consent rule, effective January 27, 2025, tightened that further by requiring consent be specific to a single seller instead of bundled across a marketing ecosystem ^[9].

A dialer earns the 'compliance-grade' label when it does four things well. It stores and timestamps consent records tied to each phone number. It scrubs against the National Do Not Call Registry on a schedule that meets the FCC's 31-day maximum staleness rule ^[10]. It enforces calling-hour windows on its own: 8 a.m. to 9 p.m. local time for residential numbers under federal rules, and often tighter under state law. And it hands you an audit trail you can export when a plaintiff's attorney asks for it.

ATDS itself is contested. The Supreme Court's 2021 ruling in Facebook v. Duguid held that a system must use a random or sequential number generator to qualify ^[4]. Predictive dialers that dial from a fixed list may fall outside that definition, but the FCC and many plaintiffs still argue otherwise in certain configurations. If your dialer uses any randomization in number selection or call pacing, you are in murkier water. Ask vendors for a written statement on how they characterize their dialing mode.

Consent management, DNC scrubbing, hour enforcement, ATDS transparency, exportable logs. Those are the safeguards. Everything else is marketing.

How do you evaluate whether a dialer's DNC scrubbing is actually reliable?

Check when the scrub happens, which lists it covers, and whether you can prove it after the fact. The FTC maintains the National Do Not Call Registry, and FCC rules require telemarketers access it no more than 31 days before a call ^[10]. That sounds simple. Vendors handle it very differently.

Some dialers scrub only at upload, meaning the moment you import your list. Import a list three weeks ago and never re-upload, and you are dialing stale data for anyone who registered since. Worse, some platforms scrub only the federal registry and skip state lists. Texas, Indiana, and Wyoming run their own DNC registries with separate registration fees and access processes ^[10].

Ask every vendor these:

• Does scrubbing happen at upload, at dial time, or both?
• Which lists do you check: federal DNC, state DNC, internal suppression?
• How recent is your copy of the federal registry, and can I see a timestamp?
• Can I upload my own suppression file of prior opt-outs and revocations?

A dialer that scrubs only at upload and only against the federal list is not doing enough. The best platforms scrub at dial time against federal DNC, state DNC where it applies, your own suppression file, and litigator lists (numbers tied to known TCPA plaintiffs and 'tester' attorneys). Litigator scrubbing is not required by law. It is practical risk management.

For high-volume teams, find a vendor that shows scrub logs per campaign. If a claim ever lands, being able to produce a log that says 'this number was scrubbed at 10:04 a.m. on date X and was clean' is material to your defense.

Which auto dialers are best for TCPA compliance in 2026?

Seven platforms have real compliance infrastructure, and they split cleanly between human-initiated dialers with lower ATDS exposure and configurable enterprise systems built for volume. Pricing below is indicative, based on published rates and industry reporting as of mid-2026. Exact quotes vary by seat count and contract length.

Platform	Dialer Type	DNC Scrubbing	Consent Storage	ATDS Architecture	Approx. Starting Price
PhoneBurner	Power/Preview	Federal + custom lists	Manual upload, CRM sync	Non-ATDS (human-initiated)	~$127/user/mo [6]
Kixie	Power + Predictive	Federal + litigator lists	Built-in log	Non-ATDS mode available	~$35/user/mo
Five9	Predictive/Progressive	Federal + state + custom	Full audit trail	ATDS-capable, configurable	~$175/user/mo [7]
NICE CXone	Predictive/Blended	Federal + state + custom	Enterprise consent mgmt	ATDS-capable, configurable	Custom enterprise pricing
Convoso	Predictive/Preview	Federal + litigator + state	Consent timestamp logs	ATDS-capable, configurable	~$150/agent/mo
Readymode	Predictive	Federal + custom	DNC log export	ATDS-capable	~$100/agent/mo
Orum	AI Power Dialer	Federal + custom	CRM-based	Non-ATDS (human-initiated)	~$300/user/mo

A few things stand out. PhoneBurner and Orum market themselves as non-ATDS because a human triggers every call. That choice cuts TCPA exposure a lot, even after Facebook v. Duguid, because there is no randomization or sequential generation involved. If your compliance team wants the clearest legal footing, a power dialer where every call is manually launched is the most defensible position you can take.

Five9 and NICE CXone are enterprise-grade and cost more, but their consent modules log opt-in source, timestamp, and method. For high-volume teams with dedicated compliance staff, that depth pays off. Both also run internal DNC scrubbing at the campaign level, so a number your company already got an opt-out from will not get called again even if it fell off your master suppression list by mistake.

Convoso deserves a mention for lead generation teams because it was early to build litigator scrubbing into the default workflow. A small group of serial plaintiffs and 'tester' attorneys files a large share of TCPA suits, so that feature removes real risk.

None of these tools make you compliant. They give you infrastructure. Compliance comes from how you use it.

What consent records does a dialer need to store to survive a TCPA lawsuit?

You need enough to prove who consented, to what, when, and for which company. The FCC's One-to-One Consent rule, at 47 C.F.R. § 64.1200, requires prior express written consent be obtained separately for each seller ^[9]. A lead form that says 'I consent to be contacted by our marketing partners' no longer covers you if you bought that lead from a third party. The consent has to name you.

For every number you dial, you should be able to produce: 1. The exact consent language the consumer saw or heard. 2. The date, time, and IP address (or a call recording) at the moment consent was given. 3. The specific phone number consented to. 4. The seller name the consent named. 5. Where consent happened: a web form URL, a verbal recording reference, a signed document ID.

Most dialers store none of this natively. They log that a call happened, not how consent for that call was obtained. That gap is where TCPA liability lives. The platforms that close it are the ones wired tightly to consent-capture tools or a CRM that holds the original lead record.

If you capture consent by SMS or a web opt-in, sms double opt-in workflows build a timestamped trail that ties a specific number to a confirmed consent event. That is the record you want behind every number in your dialer. For the disclosure language those forms need, the sms opt-in form guide covers it in detail.

One practical step before you go live: have your dialer export a sample consent record for a test contact. If the export cannot answer all five points above, close that gap before you dial at scale.

Does your auto dialer make you an ATDS user even if you don't want it to?

Not automatically, and this is one of the most common misunderstandings in outbound compliance. Buying a 'predictive dialer' does not mean you are legally an ATDS user. Buying a 'power dialer' does not mean you are safe. What matters is how the machine picks and dials numbers.

The Supreme Court in Facebook, Inc. v. Duguid, 592 U.S. 395 (2021), held that an ATDS must "use a random or sequential number generator to either store or produce telephone numbers" ^[4]. The majority read the statute narrowly. A dialer that only calls numbers from a pre-uploaded list, with no randomization in selection, arguably falls outside that definition.

Four complications remain. The FCC has not fully updated its rules to match Duguid and has signaled it may read ATDS broadly in future rulemaking. Some state laws, notably Florida's Telephone Solicitation Act (effective 2021), carry their own ATDS-like definitions that are arguably broader than the federal one ^[5]. If your predictive dialer paces calls using anything resembling sequential number generation, even internally, some plaintiffs' attorneys will argue Duguid does not save you. And the circuit courts still disagree on edge cases.

Ask every vendor one question and get it in writing: 'Does your system ever generate or select numbers using any algorithm other than sequential retrieval from a user-uploaded list?' If they cannot answer cleanly, treat the product as ATDS-capable and get prior express written consent for every cell number in your list.

For how these rules cross over into texting, the tcpa sms compliance overview explains the overlap. That matters more every year, since many dialers now fire follow-up SMS as part of a call cadence.

What calling-hour enforcement features should a compliant dialer have?

Automatic time-zone detection based on the called party's location, state-specific hour overrides, and a buffer at the edges. Federal TCPA rules under 47 U.S.C. § 227(c) and 47 C.F.R. § 64.1200(c)(1) prohibit calls to residential numbers before 8 a.m. or after 9 p.m. in the called party's local time ^[1]. The operative word is 'local.' If your team sits in Phoenix and you call New York numbers, the recipient's time zone controls.

Every serious compliance dialer enforces time zones automatically, ideally with a ZIP-to-timezone lookup rather than area code alone. Area code is imprecise because number portability means a 212 number might belong to someone living in California. ZIP-based lookup is more accurate. Some vendors pull current location from CNAM or carrier data.

State rules run tighter than federal in several places. Florida's statute limits calls to 8 a.m. to 8 p.m. ^[5]. Some states restrict weekend calling. A dialer that only enforces the federal 8-to-9 window will still dial into prohibited hours in those states.

What to look for:

• Automatic time-zone detection, ZIP or area-code based, updated regularly.
• State-specific hour overrides you can set per campaign.
• A safe-harbor buffer, say 8:05 a.m. to 8:55 p.m. local, so a call that connects one minute past the window does not become a violation.
• Holiday suppression, which matters if you call consumers who observe federal or religious holidays.

Teams that set hours manually at launch and forget about them are the ones who get caught. Enforcement that an individual agent cannot override is the right design.

How much does a TCPA violation actually cost, and does your dialer affect that?

TCPA statutory damages are $500 per call for a standard violation and $1,500 per call if a court finds the violation willful or knowing ^[1]. There is no per-plaintiff cap, and class actions aggregate thousands of calls. Reported TCPA class action settlements in recent years have clustered in the $5 million to $12 million range, based on WebRecon complaint tracking and public settlement records, though the real spread runs from small five-figure nuisance deals to nine-figure outcomes in large cases ^[8].

Your dialer moves this number in two ways. A tool with weak or missing consent logging makes it hard to show you had permission for a specific call. That turns an uncertain case into a likely loss. And a dialer that keeps calling after a consumer said 'stop' and logged that revocation is manufacturing willful violations, which triple damages to $1,500 per call.

The FCC's 2024 revocation rules require opt-outs be honored "within a reasonable time not to exceed ten business days" across all channels ^[9]. A dialer that does not sync opt-outs and revocations from SMS, email, or web forms back into its own suppression list is a liability machine.

For what courts are actually doing lately, the tcpa news today section tracks active cases and FCC orders. The facts that won or lost recent cases tell you where enforcement is pointed, which is more useful than any general rule.

Violation Type	Statutory Damages	With Trebling (Willful)
Single call, standard	$500	$1,500
Class of 10,000 calls, standard	$5,000,000	$15,000,000
Class of 100,000 calls, standard	$50,000,000	$150,000,000

What should you do before your first campaign in a new dialer?

Run a pre-launch compliance check before you dial a single number. This is not overhead. It is the line between a lawsuit and a defense.

Start with consent documentation. For every list you plan to load, answer four questions: where was this number obtained, what consent language did the person see, when did they give it, and who recorded it? If you cannot answer all four for a segment of your list, do not load it.

Test the DNC scrubbing end to end. Add a number you know is on the National DNC Registry (your own, if you registered it) to your list and watch whether the platform suppresses it before the call fires. If it does not, stop and fix that before you dial anyone.

Configure time zones and calling-hour windows before any agent can launch a campaign. Do not rely on agents to police themselves. Set the system to block calls outside permitted hours and confirm it with a test.

Export a sample call log and consent record for one test contact. Confirm the export holds everything your legal team would need in discovery: number, call time, consent source, consent timestamp, agent ID.

Set up the revocation workflow last. Test what happens when a consumer says 'remove me' mid-call. Does the system flag the number, push it to suppression, and block future calls? Run the same test with an SMS 'STOP' reply if your platform handles text follow-ups.

LeadCompliant publishes a free compliance kit with a pre-launch checklist and a consent-record template you can adapt. A structured review like this costs maybe two hours. A TCPA class action costs years.

For the broader consent architecture underneath all of this, the sms opt-in guidance covers the exact language that makes consent defensible.

Are there compliance differences between predictive dialers and power dialers?

Yes, and the gap matters a lot under current law. A predictive dialer uses an algorithm to anticipate agent availability and dials several numbers at once, routing answered calls to whoever is free. Because it dials ahead of agents, there is often a pause or dead air when the called party picks up before an agent joins. The FCC treats that pause as an 'abandoned call' if it runs past two seconds, and rules cap abandoned calls at 3% of answered calls per campaign over any 30-day period ^[10]. Predictive dialers are also easier to paint as an ATDS under aggressive plaintiff theories.

A power dialer (sometimes called progressive) dials one number per agent, only when the agent is ready. The agent triggers each call, directly or through click-to-call. No dead-air problem, and a much cleaner argument that the system is not an ATDS under Facebook v. Duguid, since no calls generate independent of human action.

If your team calls cell phones, a power dialer is the more defensible architecture right now. The infrastructure requirements (DNC scrubbing, hour enforcement, consent logging) are identical across dialer types, but the ATDS exposure is lower with a power dialer.

Some business models need the throughput of a predictive dialer. The fix is not to avoid predictive dialing. It is to hold prior express written consent for every cell number in the list and document it rigorously. Calling landlines with a predictive dialer carries far lower TCPA exposure, because the ATDS restrictions on non-emergency calls apply specifically to cell phones and pagers under 47 U.S.C. § 227(b)(1)(A) ^[1].

What compliance features matter most for real estate and insurance outbound teams?

Both industries live near the top of TCPA complaint volume for one reason: they prospect heavily to cell phones, often from purchased lead lists.

For real estate teams, the pressure points are cell phone consent for property-inquiry leads, calling-hour rules that vary by state (several are tighter than 8-to-9), and 'cold' data like expired-listing contacts who never consented to a call. The real estate text message marketing guide covers how text follow-ups to those same contacts stack a second layer of TCPA exposure.

Insurance runs hotter because lead generation there flows through third-party aggregators. After the One-to-One Consent rule took effect in January 2025, buying a shared lead and dialing it without consent that names your company is no longer defensible under the old 'I got this from a lead vendor' argument ^[9]. Insurance teams need dialers that store the original lead source and consent document, more than the phone number.

Features both verticals should prioritize:

• A consent-source field per contact, richer than a checkbox that says 'consent exists.'
• State-specific calling-hour profiles you assign by campaign geography.
• Real-time DNC re-scrub, more than at list upload.
• Opt-out syncing that reaches into the CRM, so a 'do not call' logged anywhere in the pipeline blocks the dialer.

On lead generation more broadly: the lead generation compliance news tracker helps both verticals, because enforcement actions across 2024 and 2025 have increasingly named the company that made the call rather than the vendor that collected the consent.

What red flags in a dialer vendor's sales pitch should make you walk away?

You can read a vendor's compliance posture straight from what they claim on a sales call, before you sign anything.

Red flag one: 'Our dialer is TCPA compliant.' No dialer is TCPA compliant on its own. Compliance is a function of how you use any tool. A vendor who says the product itself is compliant either does not understand the law or is hoping you do not.

Red flag two: 'You don't need written consent if you have an existing business relationship.' The established business relationship exemption is real under 47 C.F.R. § 64.1200(f)(5), but it applies only to the federal DNC Registry for residential landlines, not to the cell-phone ATDS restriction ^[9]. Using EBR to justify calling cell phones without written consent is a losing argument.

Red flag three: 'We scrub against the DNC list.' Singular. Ask which one. If they cannot name federal plus state plus your own suppression file, that is a gap.

Red flag four: vague answers about ATDS architecture. If a vendor cannot tell you in plain terms how their dialing algorithm works and whether it meets or avoids the ATDS definition after Facebook v. Duguid, ask for their legal position in writing. A confident, well-resourced vendor gives you that. One that cannot is either unsure or does not want to be on record.

Red flag five: no audit-log export, or a log only your customer success manager can pull. In litigation you need to self-serve that data fast. If the export sits behind a support ticket, your ability to answer a discovery demand is impaired.

The vendor you want says: 'Here is how our system works architecturally, here is what it does and does not do automatically, and here is where you still need a policy on your side.' That kind of honesty is the signal.

How do B2B outbound teams and international operations change the compliance picture?

TCPA covers calls and texts to US phone numbers whether the recipient is a consumer or a business. The distinction that matters is not B2B versus B2C. It is whether you are calling a cell phone.

For B2B teams dialing direct mobile numbers, every TCPA rule applies exactly as it would in a consumer context ^[1]. Calling a business's main office landline is lower risk. But if your sequence follows up by texting the direct mobile number you pulled off a LinkedIn profile, you are in full TCPA territory without consent.

For teams with European leads or customers, GDPR adds a separate consent and data-processing layer on top of TCPA. The b2b lead generation platforms gdpr compliance breakdown covers dual-jurisdiction contact records. The useful part: consent records you keep for TCPA also partially satisfy GDPR's lawful-basis requirement, so building consent storage into your dialer is not wasted effort even if your team only cares about US compliance today.

For US teams dialing Canada, the Canadian Anti-Spam Law (CASL) governs commercial electronic messages, including texts. CASL's consent rules are stricter than TCPA in some respects, and the penalties are government-enforced rather than private-action. Most US-focused dialers do not enforce CASL natively, so any Canadian campaign needs a separate review before it runs.

Frequently asked questions

Do I need prior express written consent to use a power dialer to call cell phones?

Yes, if your dialer can be characterized as an ATDS. Even under the narrow post-Facebook v. Duguid definition, best practice is prior express written consent for every cell number you auto-dial. Consent must be in writing, clearly disclose autodialing, and name your company under the FCC's 2025 One-to-One Consent rule. Without it, statutory damages of $500 to $1,500 per call apply.

How often does a dialer need to scrub against the National DNC Registry?

FCC rules require contact lists be checked against the National DNC Registry no more than 31 days before the call. Some vendors scrub only at list upload, which leaves lists older than 31 days stale. The safest setup scrubs at dial time, or re-scrubs uploaded lists automatically before any campaign that has sat idle more than a couple of weeks.

What is the difference between a predictive dialer and a power dialer for TCPA purposes?

A predictive dialer dials autonomously ahead of agent availability and is easier to characterize as an ATDS. A power dialer dials one number per agent on human initiation, which lowers ATDS exposure under Facebook v. Duguid. Both carry the same DNC and calling-hour requirements, but if you are calling cell phones without consent, a predictive dialer carries meaningfully higher TCPA risk.

Can I call cell phones using an auto dialer if I have an established business relationship?

No. The established business relationship exemption under 47 C.F.R. § 64.1200(f)(5) applies only to the National DNC Registry restriction on residential landlines, not to the ATDS-to-cell-phone prohibition in 47 U.S.C. § 227(b)(1)(A). For cell phones you need prior express written consent, regardless of any prior business dealings.

What happens if a consumer revokes consent and my dialer keeps calling them?

Under the FCC's 2024 revocation rules, you must honor opt-outs within a reasonable time, not to exceed ten business days. Calls after a documented revocation are likely willful violations, which raise damages from $500 to $1,500 per call. Dialers that do not sync revocations from all channels (call, SMS, email, web form) into one suppression list stack liability fast.

Does TCPA apply to B2B outbound calls to cell phones?

Yes. TCPA's ATDS restrictions apply to all calls and texts to US cell phones, including calls to business contacts on their mobile numbers. The consumer-versus-business distinction does not change the statute's coverage. If you are dialing a direct mobile number pulled from a LinkedIn profile or a contact database, TCPA applies.

What is a litigator list and should my dialer scrub against it?

A litigator list compiles phone numbers tied to known TCPA serial plaintiffs and attorneys who use tester calls to generate lawsuits. Scrubbing against it is not required by law, but several dialers including Convoso offer it as a default feature. Since a small group of plaintiffs files a disproportionate share of TCPA suits, scrubbing these lists is cheap, practical risk reduction.

Are there state laws that are stricter than federal TCPA for auto dialers?

Yes, several. Florida's Telephone Solicitation Act limits calls to 8 a.m. to 8 p.m. and carries its own ATDS-like definition. Washington, Oklahoma, and others run state DNC registries with separate fees. California's CCPA layers data-handling rules on top of consent. A dialer that only enforces federal TCPA defaults will still produce state-law violations in these places.

How long should I keep consent records in case of a TCPA lawsuit?

No single federal rule sets a retention period for TCPA consent records. TCPA's private right of action carries a four-year statute of limitations under 28 U.S.C. § 1658. Most compliance attorneys recommend keeping consent records at least four to five years from the last call to that number. Store them in a format you can export and search under time pressure.

What does the FCC's 2023 One-to-One Consent rule change about auto dialer compliance?

Effective January 27, 2025, the rule requires TCPA written consent name a single specific seller instead of a blanket group of marketing partners. That invalidates shared-lead consent models where one form opt-in got sold to many companies. If you buy leads, you now need consent documentation that names your company specifically, or you must re-obtain consent before dialing.

Is a click-to-call or preview dialer safer than a predictive dialer under TCPA?

Generally yes. A click-to-call or preview dialer where a human agent manually initiates every call is the most defensible architecture after Facebook v. Duguid, because there is no autonomous number generation or selection. You still need DNC compliance and calling-hour enforcement, but the ATDS classification risk drops sharply. For cell-phone-heavy lists, that architecture can matter more than any consent program.

What records do I need if a TCPA plaintiff sues me over a call my dialer made?

Four things: the call log showing time, date, number dialed, and agent ID; the consent record showing when and how consent was obtained, the language the consumer saw, and your company name in it; the DNC scrub log confirming the number was clean at the time; and any opt-out or revocation records for that number. If your dialer cannot produce all four on short notice, you are at a serious disadvantage.

Can a small outbound team afford enterprise compliance dialers, or are there lower-cost options?

Yes. PhoneBurner starts around $127 per user per month with solid DNC scrubbing and call logging. Kixie has entry tiers near $35 per user. The features you cannot negotiate away are DNC scrubbing, calling-hour enforcement, and call-log export. Free or near-free dialers rarely include these reliably. A $100-per-seat platform is cheap against $500-per-call damages at scale.

How does SMS follow-up from a dialer platform affect TCPA compliance?

Texts sent by a dialer platform carry the same TCPA consent requirements as calls, plus FCC rules under 47 C.F.R. § 64.1200 specific to SMS. If your dialer fires automated follow-up texts after a call attempt, you need prior express written consent for those texts separately from any consent you hold for the call. Many teams miss this and create SMS-specific liability on top of call liability.
