Predictive dialers are a type of auto-dialing software used in outbound sales to maximize agent productivity. The name is derived from the system’s key ability to predict agent availability and dial the next contact in a queue, even before the previous call ends. 

Originally designed by Douglas Samuelson in the late 1980s, the technology has since moved from analog to digital solutions and become a common feature in VoIP call center systems, sometimes also known as a hosted predictive dialer.

Auto Dialers are an umbrella term for hardware and software systems that allow users to make calls without needing to manually dial phone numbers.

Predictive, power, and smart dialers are all auto dialers.

Predictive dialers are systems that can anticipate call center capacity and initiate multiple calls simultaneously to effectively utilize all available resources.

Sometimes, it can boost successful calls by <400%.

Power dialers make one call at a time for each available agent. They don’t require complex algorithms and are perfect for more controlled outbound campaigns.

They can help you reach 3x more customers in a day.

Smart dialers go beyond the standard capabilities of a predictive dialer and allow you to make customized adaptive call queues with a single click from your browser or CRM.

They can lower call times by <50%.


Easy to use, minimal requirements, improves number of calls made.

Capacity prediction, non-human number filtering, performance tracking.

Pacing management, workflow automation, lower call abandonment

Intelligent call pacing, adaptive algorithms, ensured compliance.


No targeting, no additional workflow automation, can lead to burnout.

Predictive dialers initiate multiple calls from a list/queue of contacts, canceling the ones that don’t get a response in a predefined time frame and routing the ones that do to available agents, which allows businesses to maximize agent productivity at the call center level. 

Meanwhile, it gives agents the time to properly attend each caller without having to worry about repetitive tasks, such as manual dialing and after-call-work (ACW), boosting customer satisfaction and conversion rates in the process.

To achieve this, predictive dialers use a pacing algorithm, which allows them to evaluate the call center’s currently available resources and adapt the number of call attempts and times between them accordingly. Predictive dialers do this based on the following factors:

  • Average Talk/Call Handle Time: How long does a successful call take to conclude?
  • Necessary Call Attempts: How many calls does the system need to make to connect?
  • Abandonment Rate: How many people cancel the call before they connect to a rep?
  • Agent Availability: How many agents are currently available to take an outbound call?
  • AM Detection: Was the phone call picked up by a human or an answering machine? 
  • Do-Not-Call: Is the specific number on a DNC list, or can it be contacted freely?
  • Callback: Will this specific contact attempt require an agent to call back later?

The cost of a predictive dialer largely depends on the provider, the number of users, deployment, and additional features. Due to that, it’s difficult to give a specific number, but you can expect to pay anywhere between a few hundred to a few thousand dollars. On top of that, standalone dialers are fairly rare, so you may have to choose from a limited number of providers and end up paying more than you feel comfortable with. 

So, what should you do?

As mentioned above, predictive and other sales dialers are often bundled with other powerful automation features in VoIP and next-gen business calling solutions, such as CloudTalk. This allows you to get the most bang for your buck, as you can access 100+ features, including both a Power and Smart Dialer, and 35+ market-leading integrations for just $25 per user/month.

Furthermore, CloudTalk’s hosted sales dialer software is quick to deploy (1-7 days) thanks to its no-code architecture, easy to use, and fully remote-friendly. With this in mind, the question is…

If it makes sense for your business and nothing else will do, then absolutely!

But you don’t have to take our word for it. You can see it in action yourself.
