Call Center dialers let you scale up your operations, automate mundane tasks, and provide reports that can help you make strategic business decisions. They should be chosen carefully by evaluating your business requirements.

Automation technology makes jobs quicker and simpler. It can improve the efficiency of your call center.

As call center technology evolves, contact center dialers are trying to improve the overall productivity of the call center.

Earlier, agents spent their time on manual processes like sorting the customer numbers, reading their details, and manually dialing the number. That’s a waste of call center agents’ time that can be used to focus on other tasks. A call center dialer helps by automating the calling process in contact centers.

All these tedious and time-consuming processes can be automated using auto-dialers. This article explains everything about call center dialers and auto-dialers.

Let’s get right into it.

What is a Call Center Dialer?

A call center dialer is an outbound dialer software that automates the process of outbound calling or sending out the campaigns such as voice mails, broadcasting, or SMS. Contact center dialer makes the life of call center agents easier by eliminating many manual tasks.

Intelligent call center dialers automate the calling process and bring in the touch of analytics and data, which helps organizations make informed and data-driven decisions for customer service and business communication strategy.

There are many various kinds of auto-dialers available, and you may choose the one that best suits your company’s demands.

Types of Call Center Dialer

Businesses can choose from a wide range of call center dialers in the market with different technologies and functions based on the business needs.

There are 3 types of auto dialers available – predictive, progressive, and preview dialers.

Let’s now look at the features of the three dialers to help you choose the most appropriate dialer based on your company’s specific requirements.

#1. Predictive Dialer

A predictive dialer is an excellent choice for large businesses with high search volumes. Its intelligent algorithm underpins many data such as agents’ average time on the call, agents’ performance, and past trends to predict their availability and the best time to initiate the call.

Predictive dialer dials numbers from the list and transfers the call to the available agent once connected. This dialer also displays the customer connectivity status like call connected, call abandoned, call answered robot, line busy, etc., using the answering machine detection. Only when a person answers the call, is it routed to a live customer service representative.

Predictive dialers start dialing before the agent’s call gets over to reduce the idle time. For instance, if the predictive dialer algorithm predicts that the agent’s current call will end in another 40 seconds, the dialer might start dialing the numbers 10-15 seconds before that.

Predictive dialer effectiveness depends on variance factor, max pacing ratio, agents’ wait time, and call drop ratio.

Dialing ratio, call reporting, ringing strategy, integration capabilities, customization options, time zone-based calling, and skill-based routing are some of the considerations that company owners should keep in mind while setting up the fast dialer in a contact center.

A predictive dialer ensures flawless outbound calling with several other benefits. These include reduced agents’ idle time, maximizing efficiency and productivity, better call connect ratio, more talk time, and fewer unanswered calls.

#2. Progressive Dialer

Progressive dialers dial the customer number only when the agent from the previous call becomes available. Unlike predictive dialer, it doesn’t predict the call time or agent availability time to make calls. It stops calling if the agent is not present.

The progressive dialer is implemented basically to reduce the agent’s manual effort to find and dial the numbers. At the same time, it gives the agent a few seconds between calls to have a break and reduce stress.

A progressive dialer is an inexpensive option compared to other auto-dialers. Its benefits include better customer engagement, increased agent productivity, and a lower call abandonment rate.

This call center auto dialer is ideal for small to mid-call centers, b2c operations, and sales.

#3. Preview Dialer

A preview dialer is a basic outbound auto dialer that reads the existing customer data or numbers in the list to suggest the number to be contacted by the agent.

Preview dialer software also displays all the information regarding the customer, like previous calling data and personal information that helps agents personalize the call.

Preview dialing also gives agents an option to decide whether to call the particular customer or not based on the previous interaction data. Customer interaction history also helps agents personalize their sales pitches and their conversation.

This dialer is primarily used in the b2b sales campaigns as it makes call center agents more efficient.
