The short answer
Cold calling software is a dialer: it places your calls, logs each one to your CRM and lets a rep talk to more people per hour. For B2B teams, Orum, Nooks, Salesfinity and Skipcall dial several numbers at once, Kixie, PhoneBurner, Aircall, JustCall, CloudTalk and Dialpad offer power dialing, and Close builds a dialer into its CRM. On published plans, a power dialer starts at about $40 to $50 a user a month billed annually, and parallel dialers run from $70 a month to quote-only (vendor pages, read November 10, 2026).
Every dialer needs numbers that reach people. Add direct dials and mobiles to your list on find phone numbers, and check the numbers you already hold with the phone validator.
The numbers to call: Cleanlist AI (our product).
Disclosure. We make Cleanlist AI. Its 98% verified email and 85% direct dial figures come from our own 500-lead benchmark, which named no other vendor.
Cleanlist AI is not a dialer and places no calls. It finds the people you want to call and their verified phone numbers, direct dials and mobiles, and you load them into whichever dialer below you pick. It runs waterfall enrichment across 25+ data providers in sequence and stops at the first deliverable result, at 10 credits per phone number, and a missed number costs nothing.
Facts checked November 10, 2026. Every price and feature below was read on the vendor's own page that day, and every rule on the FTC's or FCC's own page. We did not test these dialers, so nothing here is a measured result about any of them.

Calling inside HubSpot, Salesforce, Salesloft and Outreach (unranked)
Many teams already pay for calling inside their CRM or sales engagement platform. Check what you have before you buy a dialer. All four were read on their own pages on November 10, 2026.
- HubSpot. Calling comes with Sales Hub and Service Hub on Starter, Professional and Enterprise, with 500, 3,000 and 12,000 minutes per account a month. Calls are recorded and logged on the contact record, a calling queue lines up the day's calls, and dialers such as Aircall and RingCentral connect through HubSpot's App Marketplace.
- Salesforce. Sales Dialer is an add-on license for Sales Cloud and Service Cloud, from Essentials to Unlimited. Salesforce's help page says Sales Dialer is scheduled for retirement and recommends Salesforce Voice for calling inside Salesforce, and most dialers on this list sync with Salesforce.
- Salesloft. The dialer is part of the Salesloft platform, with one-click calling, LocalDial, which calls from a number with the prospect's area code, voicemail drop and one-to-one texting. Flat-rate talk and text plans are sold through its sales team.
- Outreach. Outreach Voice places calls inside Outreach, and its sequential dialing works through call tasks on its own: when a number goes unanswered, it logs the call and dials the prospect's next number.
What is an automated cold calling system?
An automated cold calling system is a dialer that takes manual dialing off the rep. It loads a call list, dials the numbers, skips or logs the ones nobody answers, and writes every outcome to the CRM, so the rep's time goes on conversations. "Auto dialer" is the umbrella term, and it covers several dialing modes.
| Dialer type | How it dials | Who it fits | What to watch |
|---|---|---|---|
| Click-to-call | The rep clicks a number and the software dials and logs it | Few calls a day, each one researched | The slowest mode |
| Preview | Shows the record first, and the rep chooses to dial | Complex accounts and senior buyers | Reps can stall on research |
| Power (progressive) | Dials the next number as soon as the last call ends, one line at a time | Most B2B reps making calls every day | One conversation per dial at best |
| Parallel (multi-line) | Dials several numbers at once and connects the first person who answers | SDR teams working large lists | The other calls that answer are dropped |
| Predictive | Paces dials to when it expects an agent to be free | Call centers with many agents | Abandoned calls, covered by FTC rules where they apply |
| AI voice agent | Software holds the conversation in a generated voice | Inbound calls and people who agreed to be called | FCC rules on AI-generated voices |
For a B2B team, our rule of thumb is to start with power dialing and move to parallel dialing once reps spend most of each hour waiting for someone to answer. Two vendor facts show the range: Kixie's multi-line plan dials up to 4 lines, and CloudTalk's parallel add-on and JustCall's predictive dialer up to 10.
Parallel and predictive dialing raise one rule to know. Where the FTC's Telemarketing Sales Rule applies, a call counts as abandoned when the person who answers is not connected to a sales representative within two seconds of finishing their greeting, so the answers a parallel dialer drops can count as abandoned calls. The next section covers the limits.
Dialer rules: what the FTC and FCC say about automated calls
This section is general information from the FTC's and FCC's own pages, read November 10, 2026. It is not legal advice. State laws add rules of their own, so ask your counsel about your own calls. Our cold calling lists guide covers the Do Not Call Registry, its fees and the business exemption in full. This section covers the rules that bear on how a dialer dials.
Calls to businesses. The FTC's Q&A for telemarketers says most calls to a business made to solicit sales from that business "are exempt from the Do Not Call provisions" (edited September 2026), and its guide to the Telemarketing Sales Rule says most calls between a telemarketer and a business are exempt from the rule. The guide names two limits: calls selling nondurable office or cleaning supplies, and calls to business lines that ask employees to buy for their own use.
Abandoned calls and predictive dialers. Where the rule applies, the FTC's safe harbor asks for four things. Abandon no more than 3% of calls answered by a live person, measured over each 30-day period, or over the whole campaign if it runs less than 30 days. Let unanswered calls ring for 15 seconds or four rings. Play a recorded message with the seller's name and phone number when no rep is free. And keep records that show all three.
Hours and caller ID. Where the rule applies, it bars calls outside 8 a.m. to 9 p.m. local time at the place called unless the person agreed, and it requires the caller's number, and name when available, to show on caller ID. The FCC's consumer guide, last updated February 27, 2026, says telemarketing calls to homes are prohibited before 8 a.m. and after 9 p.m., and that telemarketers must honor a do-not-call request made during a call at once.
Mobiles and automated calls. The same FCC guide says callers need oral or written consent before an autodialed or prerecorded call or text to a wireless number, and prior written consent before a prerecorded telemarketing call to a home or wireless number. The FTC's business exemption belongs to the FTC's rule, and the FCC's consent rules are separate, so the mobiles on a B2B list need care. One common approach, explained in the cold calling lists guide, is to keep mobiles in their own queue and dial them by hand.
AI voices. The FCC guide also says AI-generated voice calls are illegal unless the consumer agreed to receive them or the caller is exempt. Several vendors above sell AI voice agents, so read that line before you point one at a cold list.
Where the numbers come from
A dialer dials whatever list you load. If half the rows are switchboards, old numbers or missing, the fastest dialer still connects reps to no one. Three of our own tests show how much phone coverage varies by source:
- The Cleanlist AI 500-Lead Enrichment Benchmark, our own test run on a 500-lead sample: Cleanlist AI returned 98% verified work emails and 85% phone numbers.
- Our 100-lead test: Apollo returned a verified email for about 80% of leads and a phone number for about 45%.
- Our 1,000-lead test in March 2026: ZoomInfo matched 67% of mobile numbers against Apollo's 41%, with no Cleanlist AI arm.
The benchmark write-up has the method for the first two, and our Apollo vs ZoomInfo test has the third. The lesson for anyone buying dialer seats: run 50 to 100 of your own target contacts through your phone data source first, and count how many come back with a direct dial or mobile.
Which number you load matters too. A direct dial or mobile reaches the person, and a switchboard reaches a receptionist. Our guide to direct dial phone numbers explains the line types and what a number costs by vendor, our phone validation tools comparison covers checking numbers in bulk, and the cold calling glossary entry covers the practice itself.
How to choose cold calling software
| Your situation | Start with | Why |
|---|---|---|
| 1 to 3 reps who call part of the day | Close Growth, JustCall Pro, Aircall Professional or CloudTalk with the power dialer | A published price and a power dialer on a standard plan |
| An SDR team calling most of the day | Orum, Nooks, Salesfinity or Skipcall | Parallel dialing raises conversations per hour |
| Your team lives in HubSpot | HubSpot's included minutes first, then Kixie, Aircall or CloudTalk | All three name HubSpot integrations on their plans |
| Your team sequences in Salesloft or Outreach | The built-in dialer first, then Nooks or JustCall SalesPro | Both name Salesloft and Outreach integrations |
| You call outside the US | Skipcall, Orum or Salesfinity | Numbers or calling in 120+ to 160+ countries, by each vendor's count |
| You want the CRM and the dialer in one bill | Close | Calling, email, texting and the CRM on one plan |
This table is our rule of thumb from the vendor facts above. If calls are one step in a sequence with email and LinkedIn, our sales sequences guide shows where the call steps go. Before you sign, ask each vendor six questions: how many lines it dials at once, what happens when two people answer, how it protects your numbers from spam labels, which CRM fields it writes back, how it handles do-not-call requests, and whether minutes are unlimited or billed per minute.
Load your dialer with verified numbers: Cleanlist AI (our product), step by step
Cleanlist AI finds the people and their phone numbers. The calls happen in your dialer. The outbound use case shows the whole workflow around it.
- Describe who you call. Tell Clu, Cleanlist AI's GTM agent, who you sell to in a sentence, or set filters in People Search, such as job title, seniority, location, industry and headcount. It searches 1B+ profiles, and searching costs 0 credits.
- Keep 2 or 3 people per account. Pick the buyer and the user at each company so a rep has a second way in.
- Add phone numbers. Choose phone numbers on the list, or upload a CSV of the people you already have on find phone numbers. Each person runs through 25+ data providers until one returns a deliverable result. A phone number is 10 credits, a verified work email 1, and a lookup that finds nothing costs nothing.
- Check the numbers you already hold. The phone validator page explains the format and numbering-plan checks that catch bad rows, and validation inside a workspace costs half a credit a number.
- Send the list to your dialer. Export it as a CSV for any dialer above, or on Pro sync it to HubSpot or Salesforce, where most of these dialers read it.
What it costs: every new workspace starts with a 14-day Pro trial with up to 3 seats and 250 credits, enough for 25 phone numbers, plus 100 more credits when you register with a work email, and a card is required. After that, a Starter seat at $49 a month adds 750 credits, which is 75 phone numbers, a Pro seat at $89 adds 1,500, which is 150, and the Free plan keeps 50 credits a month.
Frequently asked questions
Is there free cold calling software?
None of the 11 dialers here has a free plan with a power dialer. HubSpot includes calling minutes with its paid Sales Hub and Service Hub plans, and several vendors offer trials: 7 days on Kixie, 14 days on JustCall, CloudTalk and Close, and 500 dials on Orum. Calls cost money too, through a plan with unlimited minutes or a per-minute rate.
Is there an AI to practice cold calling?
Yes. Several dialers now include practice calls with an AI buyer. Orum sells AI roleplay agents in its AI Coaching add-on, Nooks lists AI roleplay scenarios in its coaching product, and Salesfinity includes AI practice calls on both of its plans (each vendor's page, read November 10, 2026).
What is local presence dialing?
Local presence dialing calls each prospect from a number with their own area code, on the idea that people answer local numbers more often. Salesloft calls its version LocalDial, and Dialpad includes local presence dialing on Dialpad Sell Advanced. Each local number is one more number your team rents, so ask how a vendor bills for them.
What is voicemail drop?
Voicemail drop leaves a message the rep recorded in advance when a call reaches voicemail, so the rep can move to the next number without reading the same script again. Orum, Kixie, PhoneBurner, Close from Growth, Dialpad Sell Advanced and Salesloft all list it.
What is the difference between a sales dialer and contact center software?
A sales dialer is built for reps calling prospects, with CRM sync, voicemail drop and local presence. Contact center software adds queues, routing and predictive dialing for many agents, often for inbound support too. Some vendors sell both: Dialpad puts its power dialer on its contact center plans, and Aircall and CloudTalk serve sales and support from one phone system.
Does Cleanlist AI include a dialer?
No. Cleanlist AI has no built-in dialer and places no calls. It finds verified emails and phone numbers for the people you choose, and you call them from the dialer of your choice.
