What Is an Outbound Dialer?
An outbound dialer is software that automatically places calls from a contact list and passes the call to an agent once someone answers. It removes manual dialing, skips many unanswered calls and logs each attempt and outcome.
In practice, a manager uploads or syncs a list, sets a calling schedule and chooses a dialing mode. The system dials, detects whether the line was answered by a person, a voicemail greeting or nobody, and routes live answers to the next free agent. After the call, the agent selects a disposition such as "interested", "call back" or "wrong number", and the dialer moves to the next record. Recording, notes, analytics and CRM sync usually run in the background.
The same idea is sold under several names. "Auto dialer", "outbound dialing software", "outbound calling software" and "sales dialer" overlap heavily. What differs is how many calls the system places per available agent, which is the subject of the next section, and which types of auto dialers a vendor supports.
Types of Outbound Dialers
The four common modes sit on a spectrum from agent control to automation. Higher automation means more conversations per hour, and also more risk of a customer answering to silence.
Preview dialer The agent sees the contact's record first and decides when to place the call. It is slower, but it fits complex or high-value conversations such as financial advisory or account recovery. A preview dialer trades volume for preparation, and it carries almost no abandonment risk because a human triggers every call.
Power dialer The system dials one number per available agent and moves to the next as soon as the agent finishes. A power dialer removes manual dialing and the pause between calls, while an agent is always ready when a person answers. It suits small and mid-sized teams, since it needs no pacing algorithm.
Progressive dialer A progressive dialer also places one call per agent, but it dials only when the agent is marked available, and it often shows the contact record while the call rings. Some vendors use "progressive" and "power" interchangeably, while others, such as Five9, describe progressive as pacing that adjusts to campaign performance. Ask each vendor how it defines the term.
Predictive dialer The system dials more numbers than there are agents, using an algorithm that forecasts how many calls will be answered and how many agents will be free. This produces the highest talk time for large teams, and it is the mode that creates abandoned calls when the prediction is wrong. For the trade-offs, power dialer vs. predictive dialer is the decision most buyers face.
A fifth mode, parallel dialing, has become common in sales tools. One rep gets several lines dialed at once, and the first person to answer is connected. It behaves like a predictive dialer for a single seat, so the same abandonment concerns apply.

The 9 Best Outbound Dialers in 2026
Each entry covers what the product is, how its dialing works, key features and pricing as published in October 2026.
1. PhoneBurner
PhoneBurner is a US sales dialer built around the power-dialing model. A rep loads a list, starts a session and the system dials the next contact as soon as the previous call ends, with CRM records updating in the background. It markets itself to sales teams in financial services, mortgage, insurance, political and solar work, and lists integrations with HubSpot, Salesforce, Zoho CRM, GoHighLevel, SugarCRM and Monday.
Its distinguishing features focus on connect rate rather than dialing speed. Connect Scores use carrier signals to rank numbers by their likelihood of being answered and skip those with very low odds, and the ARMOR add-on monitors numbers for spam flags. Calls run on a Tier 1 carrier network, and the company lists SOC 2 Type II certification. Its answer-rate figures are vendor claims, so test them on your own list. Advanced answer-rate analytics need the ARMOR add-on on lower plans, and add-on prices are not listed.
Key features
- Unlimited power dialing with workflow automation after each call
- Connect Scores and ARMOR number monitoring (add-ons)
- Live call monitoring and coaching on Professional and Premium
- Call recording, with 30, 90 days or unlimited storage depending on plan
- SMS on Premium, with 1,000 outbound messages per month and A2P 10DLC registration required
Pricing: Standard $140 per user per month billed annually ($165 monthly); Professional $165 annually ($195 monthly); Premium $183 annually ($215 monthly). Extra outbound SMS costs $15 per 1,000 after the monthly limit.
2. Kixie
Kixie is a sales communication platform that combines a business phone with a PowerDialer and CRM integrations. Its three plans differ mainly in dialing: Professional has no PowerDialer, the Single-Line plan adds a one-line dialer with session management, and the Multi-Line plan dials up to four lines at once. Because multi-line dialing connects the first person to answer, it behaves like a small parallel dialer for one rep.
Kixie is aimed at sales and SDR teams that live inside a CRM. All plans include unlimited calling minutes in the US and Canada, a developer API, voicemail drop, click-to-call and text, automations and live call coaching. Conversation Intelligence and ConnectionBoost, a call-quality feature, are premium add-ons, and Do Not Call registry checks are sold as a compliance add-on. A seven-day free trial without a credit card is offered.
Key features
- Single-line and multi-line (up to four lines) PowerDialer
- Voicemail drop and calling session management
- CRM integration, automations and click-to-call or text
- Live call coaching and AI call analysis (add-on)
- DNC list compliance checks (add-on)
Pricing: Not published on the pricing page; pricing is provided through a demo request. Add-on prices are not listed.
3. CloudTalk
CloudTalk is a cloud phone system and call center platform headquartered in Europe, with outbound dialing built into its plans. The power dialer calls contacts one at a time from an imported list, with campaign scripts, tags, attempt limits and surveys, and the Smart Dialer builds call queues from CRM views or numbers on web pages. Parallel dialing, which rings up to 10 lines at once, is a paid add-on.
It suits small and mid-sized teams that call across borders, since it offers numbers in 160+ countries and integrates with Salesforce, HubSpot and Pipedrive. Recording, transcription, live monitoring, sentiment analysis and voicemail drop are part of the platform, and CloudTalk says its tools support TCPA, GDPR and DNC compliance. Predictive dialing is not listed on its pricing page.
Key features
- Power dialer included in Expert; add-on for Starter and Essential
- Smart Dialer built from CRM views
- Parallel dialing add-on for up to 10 lines
- Live call monitoring, recording and AI conversation intelligence (add-on)
- Numbers in 160+ countries for multi-country campaigns
Pricing: Starter €25 per user per month billed annually (€34 monthly); Essential €29 (€39); Expert €49 (€69, 3-license minimum). Power dialing is €15 per user per month on Starter and Essential, parallel dialing €39, and AI Conversation Intelligence €9. US and Canada customers pay an additional 11% compliance and administrative fee on the subscription, and prices exclude taxes.
4. JustCall
JustCall is a cloud phone and sales engagement platform that sells dialing in tiers. The Pro plan includes a power dialer, and the custom-priced SalesPro plan adds a sales dialer with predictive dialing up to 10 lines, plus power and dynamic dialers. That gives a growing team a path from power dialing to predictive without changing vendors.
It is designed for small teams through mid-market sales and support groups. Every account comes with two phone numbers, and add-ons include local number bundles, SMS bundles, AI Review Assist and an AI voice agent priced down to $0.15 per minute at volume. The pricing page lists Team, Pro and Pro Plus with the note "custom pricing" under the per-user price, so the final quote may differ from the headline number.
Key features
- Power dialer on Pro; predictive dialing up to 10 lines on SalesPro
- CRM integrations and call recording
- Local number bundles for local presence
- AI Review Assist add-on and AI voice agent
- Two phone numbers per account on all plans
Pricing: Team $29, Pro $49, Pro Plus $89 per user per month billed annually, each with a 2-seat minimum. Business (10-seat minimum) and SalesPro are custom quotes. The page does not show monthly rates in the content checked.
5. Orum
Orum is a parallel dialer built for sales development teams. A rep runs a session in which the system places several calls at once, screens out voicemails and no-answers, and connects only live humans. The base plan includes parallel, power and AI dialing, with AI call summaries, objection detection, number temperature and smart lists.
Its audience is teams of at least nine reps that prospect by phone all day. Calling covers the US, Canada and 160+ other countries and regions, with voicemail drop, recordings, live listen, a call library and Slack integration. AI Coaching, which includes AI roleplay agents and scorecards, is an add-on, and the free trial is limited to 500 dials. Because parallel dialing makes the abandonment question sharper, ask the vendor how it handles the 3% rule.
Key features
- Parallel, power and AI dialing in the base plan
- Voicemail drop and sequencing
- AI call summaries, objection detection and smart lists
- Live listen, call library and recordings
- AI Coaching add-on
Pricing: Pricing is not published; it is quoted through a request form and depends on package and number of users. Plans start at a 9-seat minimum, paid plans have no dial cap, and the trial is capped at 500 dials.
6. Convoso
Convoso is an outbound contact center platform powered by predictive dialing and aimed at lead generation, insurance, financial services, home services, solar, legal, real estate and BPO teams. Its pitch is speed to lead: when a new lead arrives, the system dials within seconds, and call classification and answering machine detection keep agents from hearing voicemail greetings.
Beyond the dialer, it offers campaign automation with cadences and retry logic, plus number management that scores number health across carriers and replaces numbers that attract spam labels. A Salesforce integration and partner marketplace handle CRM connections, and a Voice AI Agent is promoted on its site. The compliance page is separate from the product page, so ask for a demo of the controls you need. Results quoted on the site, such as higher contact rates, are the company's own claims.
Key features
- Predictive and power dialing
- Speed-to-lead dialing under five seconds, per the vendor
- Answering machine detection and call classification
- Number health scoring and automated number replacement
- Salesforce integration, API and partner marketplace
Pricing: Contact sales. Quotes depend on seats, features and integrations, annual terms are the main option (the page showed 20% off), telecom carrier fees are billed separately and there is no free trial, though live demos are offered.
7. Five9
Five9 is a cloud contact center platform with a dialer that covers predictive, progressive, power and preview modes. It publishes guidance for each: predictive for more than ten active agents, progressive for fewer than ten, and power for small teams with high call volume. A preview mode shows the contact and CRM history before dialing, and a Manual Touch mode turns automated dialing off.
It targets mid-size and enterprise centers in banking, insurance, education, retail and the public sector, with collections, sales and customer service use cases. Answering machine detection and Certified Caller (STIR/SHAKEN) are included to improve connect rates. The dialer page does not describe abandonment thresholds in detail, so confirm the limits with the vendor. Five9 pricing is per concurrent seat, with SMS usage charged separately.
Key features
- Predictive, progressive, power and preview dialing, plus Manual Touch
- Answering machine detection
- Certified Caller (STIR/SHAKEN) caller ID verification
- CRM-linked customer history
- Staffing alignment to reduce agent idle time
Pricing: Digital $119 per monthly seat and Core $159 per monthly seat (USD), priced per concurrent user with a minimum of 50 seats; Plus, Pro and Enterprise tiers are quoted through sales. Usage-based charges can apply.
8. VICIdial
VICIdial is an open-source contact center suite that handles inbound and outbound calls, email and chat in one web-based agent screen. Its site describes it as enterprise-level, running anywhere from 5 to 500 agents, with skills-based routing and queue prioritization, and the agent screen is available in 16 languages. The Vicidial Group also offers VICIhost, a dedicated hosting service, for teams that do not want to manage servers.
It is best for organizations with Linux and telephony skills, since you configure carriers, servers and dialer settings yourself. The site refers to predictive dialing and auto-dial but does not detail the modes, license terms or prices, so confirm these with the project or a hosting partner before planning a budget.
Key features
- Open-source, web-based contact center software
- Predictive dialing and auto-dial
- Skills-based routing and queue prioritization
- Optional dedicated hosting through VICIhost
- Support for 5 to 500 agents, per the project
Pricing: No software price is published on the site, and hosting is quoted separately. Plan for server, carrier and administration costs on top of any license.
9. Calilio
Calilio is a cloud business phone system for VoIP calls, SMS and virtual numbers, with a Power Dialer built into the same workspace as the phone. Managers import contact lists, build campaigns, track active dialing sessions and capture a call disposition after every call. Calls, texts, voicemail and call history sit in one place, so outbound campaigns do not need a second tool.
It suits small and mid-sized outbound teams that want a dialer, shared numbers and messaging together. Bulk and scheduled SMS and A2P 10DLC registration support follow-up texting, while call recording, call notes and tags, live listen, whisper and barge-in help with coaching. AI Call Reports and sentiment analysis summarize conversations, and integrations cover Pipedrive, HubSpot, Zoho CRM, Salesforce and Pabbly Connect. Every plan includes a free number in the US, Canada or UK and a monthly bundle of free minutes and SMS that applies to calls and texts to or from US and Canada numbers.
Key features
- Power Dialer with list import, campaigns, dispositions and active sessions
- Bulk and scheduled SMS with A2P 10DLC registration
- Call recording, notes, tags and AI Call Reports
- Live listen, whisper and barge-in
- CRM integrations with Pipedrive, HubSpot, Zoho CRM and Salesforce
Pricing: Standard is $12 per user per month billed annually ($15 monthly) and Premium is $28 annually ($35 monthly). After the monthly allowance, usage is deducted from a wallet, and Calilio Hub offers prepaid calling, SMS and combo packs for specific countries.
How to Choose an Outbound Dialer
Start from your team's size and your call volume, because they decide the dialing mode more than any feature list does. Then work through the criteria below with a demo and a short trial.
- Match the mode to headcount: Under ten agents, a power or progressive dialer is usually enough. Predictive dialing pays off once you have enough agents for the algorithm to keep abandoned calls low, and vendors such as Five9 publish a ten-agent threshold.
- Check abandonment controls: If a mode can place more calls than agents, ask how it caps abandoned calls, how it reports the rate per campaign, and whether it plays the required recorded message.
- Confirm CRM sync: Calls, dispositions and notes should write back to your CRM without manual entry. Test with ten real records.
- Look at number health: Caller ID reputation, local presence and spam-label monitoring affect answer rates. Ask what is included and what is an add-on.
- Add up total cost: Include seat minimums, add-ons such as parallel dialing or number monitoring, SMS fees and carrier charges. Compare annual and monthly prices.
- Test on your own list: Run a week with a fixed list and compare answered calls, talk time per hour and conversions against manual dialing.
Compliance Rules for Outbound Dialing in the US
Outbound dialing is regulated, and the rules shape which dialer mode is safe for you. This section is general information, not legal advice, so confirm your obligations with qualified counsel.
- Abandoned calls: Under FCC rules at 47 CFR 64.1200(a)(7), a telemarketer may not abandon more than 3% of calls answered live by a person, measured per campaign over each 30-day period. A call counts as abandoned if it is not connected to a live sales representative within two seconds of the person's completed greeting. When no agent is free, a recorded identification and opt-out message is required. The TCPA autodialer rules go deeper on consent and enforcement.
- Ring time: Rule 64.1200(a)(6) prohibits disconnecting an unanswered telemarketing call before at least 15 seconds or four rings.
- Consent: Autodialed or prerecorded telemarketing calls to the lines covered by the rule require the called party's prior express written consent, and the FCC's text should be checked for the current scope.
- Calling hours: Residential telephone solicitations are restricted before 8 a.m. and after 9 p.m. in the called party's local time.
- National Do Not Call Registry: Telephone solicitations to numbers on the registry are barred unless an exception applies, and registrations stay in force until the consumer removes them.
State laws can be stricter, and some states add their own registration or calling-hour rules. A good dialer scrubs lists against Do Not Call data, enforces calling windows by time zone and reports abandonment per campaign.
Common Mistakes When Buying a Dialer
Most disappointing dialer rollouts share a handful of causes, and each is cheap to avoid.
Buying predictive for a small team With only three or four agents, a predictive algorithm cannot forecast well, so abandoned calls rise without much talk-time gain. A power dialer usually produces nearly the same conversations with less risk.
Ignoring list and number quality A fast dialer cannot fix outdated numbers or a caller ID flagged as spam. Clean the list first and monitor number reputation.
Measuring dials instead of conversations Dials per hour looks impressive on a dashboard, but talk time per hour, conversion rate and connect rate show whether the dialer is working. The call center metrics and KPIs worth tracking for outbound include connect rate, talk time and contacts per hour.
Skipping the add-on math Parallel dialing, number monitoring, AI coaching and SMS are often separate line items, and the headline seat price can double once they are included.
Leaving agents out of the trial Agents live in the tool all day. Let two or three of them run the trial and rate it before you sign an annual contract.
Next step
Ready to Get Started?
Pick the dialing mode first, then the vendor. Small teams can usually get most of the productivity gain from a power dialer with CRM sync, while larger centers with enough agents can justify predictive dialing if they have abandonment controls and a compliance process. Whatever you choose, test it on your own list, add up the add-ons and confirm the rules that apply to your calls.
Calilio's Power Dialer works alongside calls, SMS, recording and AI Call Reports in one phone system, and every plan includes a free number in the US, Canada or UK and a monthly bundle of free minutes and SMS.
Frequently Asked Questions
What is an outbound dialer?
An outbound dialer is software that places calls from a list and connects an agent when a person answers. It replaces manual dialing, logs call outcomes and usually integrates with a CRM. Sales teams, collections groups and appointment-setting teams use it to speak with more people per hour.
What are the types of outbound dialers?
The main types are preview, power, progressive and predictive, with parallel dialing as a newer variant. They differ in how many calls the system places per available agent. Preview leaves dialing to the agent, power and progressive dial one call per agent, and predictive and parallel dial several.
What is the difference between a power dialer and a predictive dialer?
A power dialer dials one number per agent and starts the next call when the agent is done, so an agent is always ready when someone answers. A predictive dialer dials several numbers per agent and uses a forecast to connect answered calls to free agents. Predictive yields more talk time for large teams but can abandon calls.
How does an outbound dialer improve call center productivity?
It removes manual dialing, skips many busy, unanswered and voicemail calls, and shortens the gap between conversations. Agents spend more of each hour talking to people and less typing numbers. Disposition codes and CRM logging also cut after-call administration, and managers get campaign-level reports.
Is an outbound dialer legal?
Yes, but US rules govern how it is used. Autodialed telemarketing calls generally need prior express written consent, abandoned calls are capped at 3% per campaign over 30 days, and the National Do Not Call Registry applies. This is general information, not legal advice, so check your situation with counsel.
How much does an outbound dialer cost?
Published prices in this comparison run from $12 to $215 per user per month for small-team tools, while enterprise contact center platforms quote custom contracts with seat minimums. Add-ons, SMS, carrier fees and number monitoring change the total. Always compare annual and monthly billing and ask for a full quote.
What is the best outbound dialer for a small business?
A power dialer with CRM sync, call recording and simple pricing is usually the best fit for a small team. Look for no large seat minimum, a trial and clear usage fees. PhoneBurner, Kixie, CloudTalk, JustCall and Calilio all offer power dialing at small-team scale. Compare them on your own list.
Do outbound dialers work with a CRM?
Most do. Typical integrations include Salesforce, HubSpot and Zoho CRM, and some tools also connect to Pipedrive or Monday. A good integration pulls contacts into the dialer, logs each call and disposition back to the record and updates lead status automatically.
What is a good connect rate for an outbound dialer?
There is no universal benchmark, because connect rate depends on your list quality, industry, time of day and caller ID reputation. Vendors publish their own figures, which are not independent. Measure your manual baseline for a week, then compare it with the dialer on the same type of list.
Can an outbound dialer help with spam labels?
Some can. Number-health tools monitor whether carriers label your numbers as spam, rotate numbers and support caller ID verification such as STIR/SHAKEN. These features reduce the risk, but they do not guarantee answers, and call volume and complaint rates also influence how carriers treat a number.
