What is an Auto Dialer?

As the term suggests, it is an automatic calling software or tool that eliminates the need for manual call dialing, thus easing the life of call center agents. An automatic dialer systematically dials phone numbers from a list of leads and connects the answered calls with available agents.

Before launching a campaign, the agent needs to upload a list of prospects in the auto-dialer software. Then the ‘Dial Rate Per Agent’ is manually set up like 1:1 or 3:1 which means 1 number per agent and 3 numbers per agent. Then the phone numbers are dialed sequentially by the software and it connects the answered calls with the available agent. Auto dialers are capable of detecting disconnected numbers, busy signals, voicemails, and unanswered phone calls. 

What is Predictive Dialer?

It is a type of auto-dialer that primarily aims at a higher calling rate by connecting with the maximum number of leads. A predictive dialer achieves this by initiating multiple calls simultaneously and directing answered calls to the available agents. 

This type of dialer makes use of Artificial Intelligence (AI) to predict the availability of the agent based on the number of available agents, the average duration of the calls, the call abandonment rate, and various other real-time stats.

Predictive dialers automatically dial a phone number even before the current call gets completed. This means that the agent can immediately move from one call to another, without wasting any time in-between. These dialers are a more evolved and sophisticated version of the traditional dialers as they make use of AI for their work. 

Just like an auto dialer, the predictive dialer can also detect disconnected numbers, voicemails, answering machines, busy signals, and unanswered numbers.

Predictive dialers offer all the benefits provided by auto dialers. However, it offers some additional benefits also. Let’s go through the main benefits of the predictive dialer:

Improved Agent Productivity

Dialing one number at a time keeps agents utilized for around 40 minutes per hour, while predictive dialing can increase utilization to 57 minutes per hour. Source

Predictive dialers primarily focus on optimizing the dialing pace, reducing idle time for agents in between calls. Agents spend more time conversing with the clients to resolve their issues. Consequently, agents are able to handle a larger volume of support tickets, improving their overall productivity. This is highly useful in handling customer support in call centers. 

Higher Connection Rates

A predictive dialer takes into consideration the historical data and the current availability of the agent to optimize call pace. The system dials phone numbers only when the agents are likely to finish their ongoing calls. This results in a constant stream of answered calls leading to higher connection rates. 


During dynamic marketing campaigns, a predictive dialer adjusts the dialing rate automatically. During peak, the dialer accelerates the dialing pace to ensure that agents are consistently engaged with potential clients. Likewise, during slow periods, it reduces the dialing pace to maintain smooth operations. 

Cost Savings

Predictive dialers make it easy to monitor outbound calling campaigns. It provides different useful metrics related to outbound calls such as the number of calls generated, the average call duration, etc. These insights help supervisors in monitoring the performance of the campaigns as well as the agents. 

Weaknesses of a Predictive Dialer

  • Agents must have the ability to promptly handle the calls one after the other
  • In case the customer representative takes too much time to connect then it may lead to abandonment of the call. 
  • Its efficiency increases in larger campaigns because of the availability of more data for the algorithm to learn better. 
  • It’s highly dependent on the algorithm. So if the algorithm malfunctions, then it may create serious risks for the business. 

Auto Dialer vs Predictive Dialer: Ideal Use Cases

Automatic Dialer Use Case

1. Conducting Customer Surveys

Suppose a market research firm makes use of an autodialer to execute a customer satisfaction survey. The auto dialer software system dials the numbers from the list and prompts the customers to participate in the survey. This streamlines the process of data collection along with a higher number of completed surveys within a shorter timeframe. 

2. Appointment Reminders

A healthcare provider can send appointment reminders to patients using an auto dialer. The software system can automatically call patients to remind them about the upcoming appointment schedule. This leads to reduced no-show rates and adds efficiency to the overall scheduling process. 

Predictive Dialer Use Case

1. Subscription Renewals and Upselling

A subscription-based service provider can use a predictive dialer to remind customers about renewals and upsell its services. As the dialer optimizes the productivity of the agents, they can engage with the clients more effectively. 

2. Fundraising Campaign

Suppose a non-profit organization uses a predictive dialer for its fundraising campaign. The dialer dynamically connects the calls with available agents. It also optimizes the call pace, thus maximizing the engagement of the donors, resulting in increased donations.

Otherwise, the chances of facing dropped calls would be high.

Some industries and businesses that can find significant advantages by using predictive dialers include sales and telemarketing companies, customer support centers, Market Research Companies, and Appointment-based businesses. 

Which Businesses Benefit Most From Auto Dialers?
