Best Auto Dialer Software for Call Centers

An auto dialer automatically places outbound calls according to the selected dialing mode, eliminating manual dialing while maintaining TCPA compliance. Auto dialers detect and filter out unanswered calls, disconnected numbers, or busy signals to ensure agents are only connected to live leads. Outbound auto dialers make lead list penetration much more efficient, dramatically decrease agent burnout, and provide a variety of campaign management features that increase conversions.

This post explains the most popular auto dialer modes, introduces you to top auto dialer providers, and highlights key auto dialer features and benefits.

Our Review of Top Auto Dialer Software

We evaluated each provider’s pricing and plans, use cases, available features, scalability, and more to choose the best auto dialer software on the market today.

Based on our criteria, the best auto dialers are:

• Five9
• NICE CXone
• Talkdesk
• Genesys
• Dialpad
• Convoso
• Aircall
• RingCentral

Five9

Five9 is a voice-only and omnichannel enterprise contact solution with multiple outbound auto dialing modes and extensive Five9 Genius AI workflow automation. All voice plans include agent scripting, AI Agent Assist, voicemail drop, post-call summaries, AMD, and dynamic local caller ID to increase the likelihood of customer pick-ups.

Each Five9 voice plan has automated TCPA and STIR/SHAKEN compliance, a manual touch mode, time-zone dialing rules, and real-time DNC list management with third-party number management integration.

Pricing+Plans

Five9 has 5 total plans, but only 4 include the Five9 Dialer. The Core plan (from $119/user/month with a 36-month contract) is a voice-only solution. The Premium plan (quote-based) is a true omnichannel CCaaS tool that adds basic quality management. The Optimum plan adds advanced quality management and basic WFM, while the top-tier ultimate plan adds advanced WFM solutions.

See our Five9 pricing guide for additional information.

Top Features

• Dialing Modes: Five9 is one of the few providers on this list that offers predictive, power, progressive, and preview dialing modes. Individual agents or agent groups can be assigned specific skills, and the dialing speed can be automatically or manually adjusted.
• Vertical and List Penetration Dialing Modes: Five9 is the only provider to offer list penetration and vertical dialing modes. List penetration mode dials only one phone number per contact (the first listed for each contact), and moves onto the next name on the list if there’s no answer. Once the first phone numbers for each contact on the list have been dialed, Five9 then dials every contact’s second listed phone number, then each contact’s third phone number, etc. Vertical dialing mode increases the likelihood of reaching each contact, as it dials all phone numbers listed for each contact before moving onto the next number.
• Web Callback: Five9’s web callback feature is ideal for fast lead follow-up, as it calls numbers that leads have entered into your website’s contract request form. Admins can configure the dialer to automatically return calls to hot leads, and schedule callbacks for additional leads at another time.

Best For

Five9 is best for enterprise-level contact centers that primarily generate leads through outbound cold calling or contact request follow-ups. Ideal Five9 users have a high daily call volume, and prioritize fast lead list penetration–meaning they often use multiple dialing modes throughout the day to ensure they reach out to the highest possible number of leads. Businesses looking for a basic or standalone auto dialer should look for Five9 alternatives.

NICE CXone

NICE CXone is a feature-rich, AI-powered omnichannel customer experience solution with outbound progressive, preview, and predictive autodialers included in all CXone plans except for their digital-only platform.

Agents can view integrated CRM and knowledge base data, current customer CSAT scores, and recent survey responses when placing outbound calls. Lead filtering, deal scoring, and automated TCPA compliance are included. NICE’s auto dialer integrates with over 140 third-party platforms.

Pricing+Plans

The NICE auto dialer is included in 6 CXone mPower plans from $94-$249/user/month.

The most affordable plan includes only voice calling, while all others are omnichannel. Agent screen recording and real-time agent coaching are available to Essential Suite ($135/agent/month) users and above, while Complete Suite ($209/agent/month) users also get access to customer surveys and conversational analytics. The top-tier Ultimate Suite ($249/agent/month) adds industry-specific AI and end-to-end customer service automation.

For additional details, see our NICE CXone pricing guide.

Top Features

• CXone Personal Connection: NICE’s Personal Connection dialer takes a “no pause” approach to outbound dialing by proactively connecting agents to the call during the AMD process. This eliminates the “pause” that causes many live leads to hang up, ensuring quality leads aren’t lost.
• EnlightenAI for Sales Effectiveness: EnlightenAI analyzes agent sales skills across 100% of interactions in real-time and post-call. Admins can review agent performance analytics, see which topics and agent behaviors generate the most sales, monitor customer sentiment throughout the sales process, and track competitor mentions. They can also review agent rankings by highest and lowest sales percentage. NICE automatically scores how likely each lead is to convert, crosstalk, objection handling, agent empathy and ownership, and more in real time.
• CXone mPower Proactive AI Agent: NICE has one of the strongest IVA voicebots on this list, anticipating customer needs and proactively calling them before they contact your business. NICE’s AI Agents are designed to automate entire outbound interactions, not transfer callers to the best available live agent. Industry-specific automations with built-in guardrails support businesses in the healthcare, education, security, government, service provider, and financial sectors.

Best For

NICE CXone is best for enterprises that have enough agents to manage high outbound daily call volumes, but are struggling to convert leads and upsell customers due to sluggish agent performance. NICE helps managers and agents alike understand the specific behaviors and sentiments that make sales successful or unsuccessful, and offers automated real-time and post-call coaching to optimize agent performance. Those that don’t need advanced AI performance and lead scoring, but instead prioritize lead list penetration and shorter sales cycles, should seek NICE CXone alternatives.

Talkdesk

The Talkdesk auto dialer includes power, predictive, and preview dialing modes, plus a pre-built Talkdesk Dialer for Salesforce. Admins can set specific caller IDs, maximum dialing rations, adjust dialer pacing, and allowable outbound calls by time zone.

Agents can set custom disposition codes, add call notes, and send out proactive SMS reminders or voicemail message reminders. AI-driven AMD, TCPA compliance, branded/verified calling, and simultaneous campaigns are also included.

Pricing+Plans

Talkdesk auto dialers are only included with Cloud CX Elevate plans, which cost $145/user/month. However, Elevate users must select Proactive Engagement as their included add-on. All other Talkdesk Cloud CX plans, which range in price from $85-$115/user/month, offer auto dialing only as a paid add-on. The 5 quote-based Experience Clouds also only offer auto dialers as potentially included add-ons, but Experience Cloud users can choose two included add-ons with their plans.

For more information, see our Talkdesk pricing guide.

Top Features

• Talkdesk Dialer for Salesforce: Available directly in Salesforce, the Talkdesk Dialer integration lets admins filter dialing lists by contacts, leads, accounts, cases, and opportunities. Admins can also specify which campaigns are priorities, set campaign start and end dates, and assign specific dialing modes to individual campaigns.
• Talkdesk Feedback: Create template-based or custom surveys and assign them to auto dialer call lists. Talkdesk analyzes customer feedback in real time and lets admins review raw data provided directly by customers. Survey analytics show CSAT score trends, NPS scores, answer rates, and more.
• Campaign Priority: Admins can set specific campaign priorities for agents that are assigned to multiple campaigns.

Best For

Talkdesk is best for businesses looking for industry-specific auto dialers for the healthcare, insurance, banking, retail, and government sectors. The Experience Clouds integrate with industry-specific software and comply with industry-specific regulations like HIPAA and FedRAMP. However, only top-tier Talkdesk plans include outbound dialing–and even then, customers must choose it as their included add-on. Teams looking for advanced campaign management features and progressive dialing should explore Talkdesk alternatives.

Genesys

Genesys Cloud CX includes a dialing system with predictive, preview, and manual dialing. Build a multichannel outbound IVA that interacts with customers via not only voice but SMS, mobile web chat, and email–with automated alert messaging, notifications, and call follow-ups.

The dialer quickly distinguishes between live calls, voicemails, and busy signals–taking the appropriate next response with advanced skills-based routing capabilities. Once the agent is connected, the Genesys CXone offers an omnichannel interface, with a customer profile and preview dialing informed by CRM and business database analytics.

Pricing+Plans

All Genesys Cloud CX plans ($75-$155/user/month) include outbound dialing modes. The most affordable plan is a voice-only solution, the mid-tier plan is an omnichannel platform with built-in quality assurance, and the top-tier plan adds forecasting and conversational analytics. Additional details are available on the Genesys pricing page.

Top Features

• Customer Opt-Ins: Genesys monitors and automates customer opt-in requests to ensure call centers remain in compliance with TCPA and DNC regulations
• Scripting Design Tools: Genesys has one of the best script design tools on this list, allowing admins to create and customize script templates, assign call flows to scripts, and use scripts to create internal knowledge base data.
• Multichannel Outbound IVR: The automated system connects with recipients via an advanced multichannel IVR menu. Provide customers with DTMF options to hear an announcement, reach a live agent, or take action–such as receiving a text notification.

Best For

Genesys is best for enterprise call centers that need to optimize agent scripts and better manage customer opt-in requests.  Because Genesys limits performance management and forecasting to its top-tier plan, those seeking built-in WFM tools should look for Genesys alternatives. Genesys also requires all users to pay add-on fees to access CRM integrations, meaning it’s not right for teams with a large existing tech stack.

Dialpad

Real-time agent assistance provides on-screen prompts, keyword tracking, and live coaching suggestions, while voicemail drop lets agents leave pre-recorded messages, reducing repetitive tasks and increasing call volume efficiency.

Pricing+Plans

Dialpad offers business phone system and contact center solutions, but only Dialpad Sell–an outbound sales platform–includes auto dialing.

Best For

Dialpad is best for outbound-only call centers looking for a user-friendly outbound dialer with basic coaching and call monitoring tools in addition to internal video meetings. Because Dialpad’s auto dialer is only available in Dialpad Sell plans, businesses looking for an omnichannel contact center or basic call center solution with a built-in outbound dialer should seek Dialpad alternatives.

Convoso

It includes campaign management tools that help track performance and improve outbound calling. Speed-to-lead monitoring reduces delays in reaching new prospects, while dynamic scripting provides agents with prompts and responses during calls.

Best For

Convoso is best for teams with extensive security and compliance needs. It’s also a good fit for newer outbound call centers that want a standalone outbound dialer, not a complete contact center. Those seeking inbound call center solutions or omnichannel contact centers should choose Convoso alternatives.

The power dialer integrates with 20 applications, allows for ring groups, has a shared call inbox, and leverages call whisper for supervisor-led agent coaching.

What Is An Auto Dialer?

An auto dialer is an essential call center feature that automatically dials the next phone number on a list of existing customers or leads, only connecting live agents when the recipient answers.

Admins can choose from several different outbound dialing modes to ensure maximum efficiency, and assign agents to specific call lists according to their skillsets. Auto dialers can dial multiple phone numbers simultaneously and drop pre-recorded voicemail messages if calls are unanswered. They automatically filter out busy or disconnected numbers, as well as numbers on company and nation-wide Do Not Call lists. They also require agents to manually press a single button to initiate each outbound call, ensuring TCPA compliance.

The most common outbound dialing modes are predictive dialing, preview dialing, power dialing, and progressive dialing. Auto dialers are available as standalone tools or as built-in contact or call center features.

Key auto dialer features include outbound IVR, voicemail drop, lead list generation and scrubbing, DNC compliance, lead scoring, automatic dispositions, campaign management tools and analytics, agent scripting, in-call agent assist, CRM integrations, and post-call summaries. Common auto dialer use cases include telemarketing and sales calls, appointment reminders, follow-up calls, emergency notifications, customer surveys, political campaigning, debt collections, and subscription renewal reminders.

Dialing Modes: Power, Predictive, Progressive, and Preview Auto Dialers

The four main dialing modes are power, predictive, progressive, and preview auto dialers. Most providers offer several or all of these dialing modes in addition to standard manual dialing. In addition to switching between dialing modes as needed, admins can customize the length between calls, the number of rings before the call is ended, whether or not the agent can adjust the dialing speed or skip numbers on a list.

Predictive Dialers

Predictive dialers use a machine-learning algorithm to determine when to dial recipients automatically, and how many recipients to dial at once. The predictive AI algorithm determines this information based on shifting metrics: how many and which agents are available, how long their calls usually last, the probability of each dialed call connecting, and how long the phone is expected to ring before the recipient answers.

Factored together, these metrics inform the predictive dialer’s “pacing algorithm,” which seeks to time calls so that all agents transition immediately from one to the next, without pauses between calls.

Power Dialers

A power dialer automatically dials phone numbers in immediate succession according to the uploaded call list, transferring answered calls to a live agent. Unlike predictive dialers, which make multiple automated calls simultaneously while an agent is on the phone, power dialers only make one call after another and don’t place simultaneous calls.

Compared to predictive dialing, power dialers eliminate the risk of connecting too soon while the agent is still on the previous call, and they provide the option for the agent to leave a voicemail or hang up.

Progressive Dialers

Progressive dialers move through your contact database one at a time, dialing new contacts only as agents become available–thus avoiding the risk of getting a customer on the line with no agent available–leading to a hangup and annoyed customer. Unlike predictive dialers, which dial multiple numbers simultaneously based on algorithmic pacing, progressive dialers ensure that a live agent is always available when a call is connected.

Preview Dialers

A preview dialer gives the agent a dashboard preview of the contact’s profile and key data before placing the call. Agents can review customer/lead contact information, account history and value, previous orders, integrated CRM data, notes from other agents, and complete conversation history. This allows the agent to prepare and make necessary adjustments before proceeding, instead of getting thrown into a call without preparation.

Key Auto Dialer Software Features

In addition to the above dialing modes, the most essential auto dialer features are:

• TCPA Compliance: Auto dialers automate TCPA compliance to ensure your call center isn’t in violation of the Telephone Consumer Protection Act. Auto dialers integrate with public and company-facing DNC lists, automatically removing customers who have opted out via lead list scrubbing. They also automate the opt-in process to ensure you’re only contacting people who have consented to hear from you.
• Call Monitoring and Recording: Auto dialers offer real-time call monitoring, automated and manual call recording, call transcriptions, and call whisper for in-conversation agent coaching and post-call quality management.
• Agent Scripting: Auto dialers help optimize the script creation process, even using transcripts of successful calls to improve current scripts. Drag-and-drop script design, dynamic scripting, and automated script personalization make the process easier than ever.
• AMD and Voicemail Drop: Answering Machine Detection (AMD) automatically skips over unanswered phone numbers after a preset number of seconds or rings (or when an answering machine is reached.) Admins can automatically send out bulk (voicemail broadcasting) or individual (voicemail drop) pre-recorded messages if calls aren’t answered.
• Outbound IVR/IVAs: Outbound Interactive Virtual Response (IVR) and Intelligent Virtual Agents (IVAs) let customers respond to pre-recorded call prompts, automatically routing them to the best available agent or answering basic support questions using Natural Language Processing. This is especially valuable for lead qualification, outbound appointment reminders (customers can confirm their appointment by saying “yes” into the phone), and customer surveys. Outbound IVAs can also automate customer data collection, freeing up live agents to focus on selling and providing personalized service.
• Agent Groups and Skill Assignment: Admins can create groups of agents with similar schedules or skill sets, then assign them to specific campaigns accordingly. Admins can rank agent skills to let agents from different departments assist one another during peak call times.
• Post-Call Summaries and Dispositioning: Auto dialers can automate the call dispositioning process according to customizable tags and categories, but post-call summaries take things a step further. These AI-powered summaries identify the main conversation topics, outcomes, key moments, and potential next steps. They often also include insights about agent performance and customer satisfaction.
• Campaign Management: Campaign management tools create lead lists from integrated sources, rate the success of individual campaigns, and determine the most effective call scripts. This makes it easier to identify which campaigns to focus on and provides real-time and historical campaign insights to optimize the sames process.
• Lead Qualification: Auto dialers evaluate each lead’s potential interest via dispositioning, survey responses, integrated CRM data, and even AI-powered conversation analytics that monitor customer sentiment and intent. Predictive analytics help you determine the best time to contact leads, prioritize hot leads, and even score leads according to custom metrics.
• Third-Party Integrations: Auto dialers integrate with popular third-party tools like CRM systems, helpdesk solutions, and marketing apps to give agents real-time access to essential customer information, knowledge base data, and call scripts.
• Coaching and Performance Management: In addition to standard call monitoring and recording tools, most auto dialers include real-time and post-call agent coaching tools. Admins can create custom agent scoresheets, automate agent performance scoring, and enable push notifications that alert supervisors to major changes in SLAs and KPIs. Admins can add notes to agent evaluations, assign relevant training modules, coach agents during active calls via chat messaging, and more. AI Agent Assist gives automated in-call next-best-action suggestions to agents based on integrated CRM and knowledge base data.

• Increased Lead Conversion: Auto dialers can increase lead conversion rates by 17%.[*] Compared to manual dialing, auto dialers increase contact rates by up to 50% and boost hourly agent talk time by up to 400%.[*] In addition to higher lead conversions, auto dialers also increase existing customer spending by identifying more upselling and cross-selling opportunities.
• Increased Agent Retention: Call centers have one of the highest agent turnover rates of any industry at roughly 38%, with many agents citing repetitive tasks, high stress, and aggressive customers as top reasons for leaving.[*] Auto dialers automate the dialing process, only connect agents to interested prospects to cut down on customer abuse, and provide dynamic scripting and in-call coaching tools to boost agent engagement and performance.
• More Successful Campaigns: AI-powered auto dialer analytics leverage conversational insights and monitor live/historical KPIs to identify the most effective campaign scripts, top-performing agents, and even the best times to contact new leads or existing customers.
• Increased Productivity: Auto dialers can increase outbound call productivity by up to 100% while lowering operating costs by up to 40%.[*]
• Higher Dial, Connection, and Contact Rates: Auto dialers improve the three most important outbound call center KPIs: Dial rate, connection rate, and contact rate. The dial rate measures the total number of calls dialed during a given time period. The connection rate measures the percentage of answered outbound calls. The contact rate measures the percentage of live agent contact with the recipients.
