Master Cold Calling with the Top Dialer Software In 2026

The strongest cold calling dialers in 2026 are Voiso, CloudTalk, Five9, JustCall, Kixie, PhoneBurner, Aircall, RingCentral, Salesloft, HubSpot Sales Hub, Orum and Trellus. They are not interchangeable, and the thing that separates them is narrower than most comparisons suggest: which dialing modes each one actually publishes, whether it is built for a sales team or a contact center floor, and what it costs once the minimum seat count is applied.

This guide compares all twelve on those terms, sets out the abandonment rules you configure against before the first campaign runs, and ends with how to pick between them. Every capability below was read on the vendor’s own website in October 2026.

The Shortlist at a Glance

Prices were read on the vendors’ own pricing pages on 12 October 2026 and change frequently, so treat them as a starting point rather than a quote.

How This List Was Built, and What It Is Not

Every capability attributed to a platform here was read on that company’s own website, not taken from a review site or another comparison article. Where a vendor does not publish a particular dialing mode, the table above leaves it out rather than asserting the product cannot do it, because an unpublished feature and an absent feature are different things and only the vendor knows which applies. Nothing here is scored, because a score invented by the company at the top of the list would tell you nothing.

What that means in practice: use this to narrow a shortlist and to understand the categories, then confirm anything decisive directly with the vendor. Several of these platforms publish no pricing at all, and several publish seat minimums that matter more than the headline rate.

The Twelve, Compared

1. Voiso

Voiso is a cloud contact center platform built around outbound calling, founded in 2018 and now running from six offices across Amsterdam, Larnaca, Limassol, Dubai, Singapore and Manila.

It publishes four dialing modes by name: predictive, power, preview and progressive, which is the widest published range on this list alongside Five9. Answering machine detection screens voicemail before the call reaches an agent, and local caller ID presents numbers local to the contact, with local numbers published in over 120 countries. Speech analytics covers transcription, call summaries and conversation scoring in ten or more languages.

The compliance position is unusually specific for this category. Voiso publishes ISO 27001 and ISO 9001 certification, states that it complies with PCI DSS and GDPR requirements, and runs six data centers with flexible storage regions supporting data residency, which matters when your campaigns cross borders.

• Integrations: HubSpot, Salesforce, Zoho, Bitrix24, Pipedrive, Freshdesk, Zendesk, Zapier, Make.com, Leverate, Doktor365.
• Pricing: not published; quoted by requirement.
• Best for: outbound teams, BPOs, collections and lead generation, particularly where certifications and data residency have to be evidenced.

2. Five9

Five9 publishes the most complete set of named dialing modes of any platform here: predictive, progressive, power, preview and a manual touch mode, alongside Certified Caller for STIR/SHAKEN attestation.

Usefully, it also publishes guidance on which mode suits which team size, putting predictive dialing with teams above ten active agents, progressive with teams below ten, power dialing with small teams handling large volumes, and preview dialing where reps personalise from CRM history. That is more candid than most vendors manage.

• Integrations: Salesforce, Microsoft Dynamics 365, ServiceNow, Oracle Service Cloud, Oracle NetSuite, Zendesk.
• Pricing: Digital at $119 per seat monthly and Core at $159; higher tiers are quoted. A 50-seat minimum applies and usage-based pricing may be added.
• Best for: established contact centers at genuine scale. The seat floor puts it out of reach for most sales teams.

3. CloudTalk

CloudTalk positions itself as call center software connected to your business tools, and sells its dialing capability in parts rather than as one bundle.

Power dialing, parallel dialing, a smart dialer and click-to-call are each published by name, with power and parallel dialing sold as priced add-ons on top of the base license. Its integration catalogue is the longest on this list by a wide margin, covering well over forty named tools.

• Integrations: HubSpot, Salesforce, Zoho CRM, Microsoft Dynamics 365, Pipedrive, Zendesk, Freshdesk, Intercom, Outreach, Gong, Shopify, monday.com, Microsoft Teams, Zapier and Make, among many others.
• Pricing: Lite from €19 per user monthly billed annually, rising through Starter, Essential and Expert at €49. Power dialing adds €15 per user, parallel dialing €39, and conversation intelligence €9.
• Best for: small and midsize teams that want to pay for dialing capability only where they use it, and that lean heavily on integrations.

4. JustCall

JustCall sells a sales dialer aimed squarely at revenue teams rather than at support operations.

Four modes appear by name, auto, predictive, dynamic and power, plus a multi-line dialer that it also describes as parallel dialing. Its predictive dialer publishes a specific ceiling, dialing up to ten numbers at once while filtering voicemails, unanswered calls and dead numbers, and the line count is configurable per campaign. A published ceiling is rarer than it should be in this category.

• Integrations: HubSpot, Salesforce, Pipedrive, Zoho CRM, ActiveCampaign, Zendesk, Freshdesk, Copper, Outreach, Apollo.io, Intercom, Slack, Zapier, with more than a hundred others listed.
• Pricing: Team from $29 per user monthly billed annually with a two-seat minimum, then Pro at $49 and Pro Plus at $89. The predictive dialer sits in a higher tier that is custom priced by team size and volume.
• Best for: sales teams wanting multi-line dialing without a contact center price tag, provided the predictive tier quote lands acceptably.

5. RingCentral

RingCentral approaches outbound through RingCX, its contact center product, rather than through the business phone system it is better known for.

Predictive, progressive, preview and voice broadcast dialing are published by name, as is call blending, which runs outbound campaigns during quiet periods and switches agents to inbound as volume rises. That last capability is genuinely distinctive and suits teams whose people handle both directions.

• Integrations: Salesforce, HubSpot, Zendesk, Microsoft Teams, Oracle and Google among more than fifty connected tools.
• Pricing: RingCX is published as starting at $65 per user monthly with unlimited minutes; individual plan names and tier prices are not published.
• Best for: organizations that want contact center and unified communications from one vendor, and teams whose agents switch between inbound and outbound through the day.

6. PhoneBurner

PhoneBurner has stayed deliberately narrow, publishing power dialing and nothing beyond it, and building around answer rates instead of line counts.

Its distinguishing feature is ARMOR, a dedicated spam protection and answer rate service sold alongside the dialer. Where your numbers are being labelled as spam by carriers, that problem costs more than any pacing setting will recover, and few competitors address it as an explicit product.

• Integrations: Salesforce, HubSpot, Zoho CRM, GoHighLevel, SugarCRM, monday.com, with over 150 listed.
• Pricing: Standard at $140 per user monthly billed annually, Professional at $165 and Premium at $183, among the highest entry points here.
• Best for: relationship-led outbound in financial services, mortgage, insurance, political and solar, where conversation quality outweighs raw dial volume.

7. Kixie

Kixie builds around a multi-line PowerDialer paired with AI voice detection, and lives inside the CRM rather than beside it.

The product is aimed at sales development and account executive teams, with role-specific material for inside sales, business development, revenue operations and support. Add-ons published alongside the dialer include ConnectionBoost, conversation intelligence and do-not-call list compliance, the last of which is worth noting because DNC handling is more often buried than sold.

• Integrations: Salesforce, HubSpot, Pipedrive, Zoho, Copper, Insightly, Freshworks, monday.com, HighLevel, Close, Zapier and Make.
• Pricing: none published. Plans are selected by calling volume and feature requirements, with a seven-day trial offered without a card.
• Best for: sales development teams working primarily inside a CRM who want multi-line dialing and are comfortable going through sales for a quote.

8. Aircall

Aircall is a cloud phone system for sales and support teams, with a power dialer that auto-dials from the CRM and logs every call without manual entry.

It detects numbers on a web page and works through them in sequence, which suits prospecting from lists that live outside a formal CRM record. Click-to-dial is published separately. Deployment speed is the recurring theme in its material, and the integration count is substantial.

• Integrations: HubSpot, Salesforce, Zendesk, Pipedrive, Microsoft Teams, Bullhorn, monday.com, Shopify, with more than 250 native connections published.
• Pricing: Essentials at $30 per license monthly and Professional at $50, both with a three-license minimum; Enterprise is custom with a 25-seat minimum. Annual payment carries a published discount.
• Best for: smaller sales and support teams wanting a phone system first and a dialer second, with setup measured in days.

9. Orum

Orum is a parallel dialer built specifically for sales development, and it addresses the problem that makes parallel dialing uncomfortable.

Dialing several lines at once risks the rep arriving mid-greeting or landing on a phone tree. Orum’s Operator component handles screeners and phone trees and connects the rep only once a person is actually present, and where two people answer at once the rep is connected to whoever picked up first while the other number is saved for later. It publishes no line count.

• Integrations: not named on the pages read.
• Pricing: none published. Plans are named Launch and Ascend, priced per user and billed annually, with a nine-seat minimum and add-ons for lighter users, AI coaching and webhooks.
• Best for: SDR and BDR teams of nine or more running high-volume prospecting where the opening moment of the call matters.

10. Trellus

Trellus takes a different shape again, running as a copilot inside the sales platform your reps already use rather than replacing it.

It is the only platform here publishing a specific parallel line count, dialing up to five lines at once, alongside automated voicemail drops and real-time coaching in the same tab. Self-service is part of the positioning, with licenses available immediately and no sales call required.

• Integrations: works inside the sales engagement platform rather than integrating separately.
• Pricing: Power and Power plus Parallel are published with two figures each, $99.99 and $149.99 alongside a lower $34.99 figure, without labelling which is standing and which is promotional. The business tier is custom.
• Best for: individual reps and small teams wanting parallel dialing layered onto existing tooling without changing platforms.

11. Salesloft

Salesloft is a sales engagement platform where calling is one component of a broader cadence, rather than a dialer that gained a workflow.

It publishes no dialing mode in the power, predictive, progressive, preview or parallel vocabulary at all. What it does publish is calling features: LocalDial, intelligent call pass through, pre-recorded voicemail drop, one-to-one SMS, and Live Call Studio, which lets managers listen in, whisper advice or join a live call. For teams whose calls sit inside multi-touch sequences, that integration matters more than pacing does.

• Integrations: a partner marketplace is referenced, though no third-party tool is named on its own calling pages.
• Pricing: none published; plans are unnamed and routed to sales.
• Best for: SDR teams running coordinated email and phone cadences who want calling inside the sequence rather than beside it.

12. HubSpot Sales Hub

For teams already standardized on HubSpot, the calling question is often answered by the CRM itself.

Calls are placed from the browser and tracked natively in the Smart CRM, with a sales power dialer published in beta that queues calls from the CRM and can drop voicemails. The calling notetaker produces real-time transcription and summaries, and call tracking, conversation intelligence and analytics sit in the same editions. No other dialing mode is published.

• Integrations: native to HubSpot Smart CRM; no third-party calling integration is named on the calling pages.
• Pricing: calling is bundled into Sales Hub editions rather than priced separately. Sales Hub Starter begins at $10 per seat monthly, Professional at $100 and Enterprise at $150, with a free tier available.
• Best for: teams whose pipeline already lives in HubSpot and whose call volumes do not justify a separate platform.

Which Dialing Mode You Actually Need

The platform matters less than the mode, and the mode follows from your connect rate rather than from your headcount. The six dialing modes differ in how many numbers go out per free rep.

Predictive dialing is oversold and preview dialing is undersold. Predictive earns its complexity where only a small share of numbers answer, because the gap it fills is large. Where half your list picks up, progressive or power delivers most of the throughput without the abandoned calls, and an abandoned call on a cold campaign costs twice over, in regulatory exposure and in teaching the market to stop answering your numbers.

Parallel dialing is the newest arrival and carries the same exposure as predictive, with an added failure mode: a rep landing mid-sentence or on a phone tree. Ask any parallel vendor how it handles the connection moment before you judge it on line count.

What the Rules Require Before You Dial

Cold calling is lawful in most markets and specifically constrained in all of them, so the question is never whether you may call but under what conditions. Business-to-business calling is generally treated more permissively than consumer calling, though not universally.

In the United States, two rules set the pacing limits. The FTC’s Telemarketing Sales Rule at 16 CFR 310.4 prohibits abandoning outbound telemarketing calls and provides a safe harbour for sellers whose technology keeps abandonment to no more than three percent of calls answered by a person, measured over a single campaign of under 30 days or separately across each successive 30-day period. The same rule treats a call as abandoned where the telemarketer fails to connect it to a sales representative within two seconds of the person’s completed greeting, and requires letting an unanswered line ring for at least fifteen seconds or four rings.

The FCC’s parallel provision at 47 CFR 64.1200 sets three percent as the limit itself over a 30-day period per campaign, applying the same two-second test. Both compute per campaign rather than across your whole operation, so a well-paced campaign cannot absorb a badly paced one.

Consent is the other half. The Commission’s telemarketing guidance explains that its rules cover calls using an automatic telephone dialing system, and that in 2012 it revised those rules to require callers to obtain prior express written consent before making telemarketing robocalls. What counts as an autodialer has been litigated in federal court and the rules have been amended more than once, so take current advice rather than treating this as settled.

Three things follow for your configuration. Measure abandonment per campaign and watch it while the campaign runs. Keep consent and opt-out records at the contact level, since a suppression list you cannot evidence is not a defence. And treat all of the above as United States rules only, because dialing into the United Kingdom, the European Union or elsewhere brings different pacing, consent and caller presentation requirements that follow the destination rather than your head office.

How to Choose Between Them

Four questions narrow twelve options to two quite quickly.

What is your actual connect rate? Below roughly a fifth, predictive or parallel dialing earns its keep. Above that, power or progressive gets you most of the throughput with far less exposure, and the simpler platforms become viable.

How many people dial simultaneously? Predictive pacing needs enough concurrent reps to forecast against. Below a handful calling at once there is too little to predict, and you get idle reps or abandoned calls. Several platforms here publish seat minimums of nine, twenty-five or fifty, which settles the question before features do.

Where does your pipeline live? Where everything already sits in one CRM, a native dialer removes an integration project. Where you run genuine campaign volume, a contact center platform gives you pacing controls and per-campaign reporting the CRM-native options do not publish.

Who changes the pacing? If adjusting a dial ratio needs a support ticket, your pacing will be wrong for weeks at a time. Ask to see it changed during the demo.

Then pilot on real lists with real reps for long enough to see a bad week. A platform reps quietly work around, by keeping a side spreadsheet or dispositioning everything the same way, produces excellent reports and no information.

What to Test During the Pilot

Demos are built to succeed, so the pilot is where the decision actually gets made. Four things are worth deliberately provoking.

Run it on a genuinely poor list as well as a good one. Predictive and parallel pacing both degrade when the data is stale, because the algorithm is forecasting against connect rates that keep moving, and you want to see how the platform behaves and what it reports when that happens rather than discovering it in month three.

Watch a supervisor fix a pacing problem live. Ask for abandonment to be pushed up deliberately and then brought back down, and time how long the round trip takes. If it involves a support ticket, you have learned something more useful than any feature list.

Check what reaches the CRM, on your own instance with your own fields. Call logged is not the same as outcome written, recording attached and the record updated, and the difference becomes a data problem six months later rather than a calling problem next week.

Finally, ask the reps. A platform people quietly work around, by keeping a side spreadsheet or dispositioning everything the same way, produces excellent reports and no information at all.

Frequently Asked Questions

What is the best dialer for cold calling?

It depends on your connect rate, your team size and where the pipeline already lives, which is why this guide compares twelve platforms rather than naming one. Voiso suits outbound teams needing several dialing modes alongside published certifications and data residency. Five9 fits large floors, subject to a fifty-seat minimum. CloudTalk, JustCall and Aircall serve smaller sales teams at lower entry prices, while Orum and Trellus specialise in parallel dialing for prospecting at volume.

What is the difference between a power dialer and a predictive dialer?

Power dialing places a fixed number of calls for each available rep, a multiple you configure yourself, so pacing stays predictable and easy to tune. Predictive dialing forecasts when reps will become free and varies the dialing rate continuously, producing higher throughput and carrying more abandonment risk, since calls go out before anybody is available to take them. Power gives you control over the ratio, predictive gives you volume and asks you to monitor the consequences.

Is B2B cold calling illegal?

No, though it is specifically regulated and the conditions differ by market and by the type of line dialed. United States rules cap abandoned telemarketing calls at three percent per campaign, require connection within two seconds of the greeting, and impose consent requirements for automated calls to mobile numbers. Other markets apply their own consent, screening and caller presentation rules. Business numbers are generally treated more permissively than consumer numbers, but not everywhere, so take advice per market.

Is a parallel dialer better than a predictive dialer?

They solve the same problem differently and carry comparable exposure. Parallel dialing places several calls per rep simultaneously, while predictive dialing forecasts availability across the whole team and paces accordingly. The deciding question for parallel dialing is what happens at the connection moment, since a rep arriving mid-greeting or landing on a phone tree wastes the connection the dialing bought. Ask how screeners and automated menus are handled before comparing line counts.

How much does a cold calling dialer cost?

Published entry prices among these twelve ranged from $10 per seat monthly for HubSpot Sales Hub Starter to $140 for PhoneBurner Standard when read in October 2026, with several publishing nothing at all. Headline rates mislead, though: seat minimums of nine, twenty-five and fifty apply at various platforms, dialing capability is sometimes a paid add-on rather than included, and the modes most useful for cold calling frequently sit in quote-only tiers.

Which dialer suits a small sales team?

Smaller teams usually do better with power or progressive dialing and tight CRM integration than with predictive dialing, which needs enough concurrent reps for forecasting to work. Watch the minimums: several platforms on this list require nine, twenty-five or fifty seats before you can buy at all. Prioritise what writes back to the CRM, whether a non-technical manager can adjust pacing, and whether the dialing mode you need sits in the entry tier or a higher one.

Talk Through the Pacing Before You Commit

Most underperforming outbound campaigns turn out to be a pacing or list problem wearing a tooling problem’s clothes, and both become visible within a week once abandonment, connect rate and conversations per rep sit in one view.
