Thus, auto dialers are segmented into different categories:

  • Preview dialer
  • Progressive dialer
  • Predictive dialer 

What is a preview dialer?

A Preview dialer provides a facility to agents to choose whether they want to attend a call or not. It shows a “preview” of lead records and product information before dialing a number. In some cases, the preview dialer shows the customer preview after dialing a call. If the agent skips the call, it is transferred to another agent in the list. This assists to improve sales calls and guarantees agents are completely ready prior to engaging with prospects. This auto dialer is excellent for small call centers running telesales and telemarketing campaigns.

What is a progressive dialer?

It automatically places a call only if an agent is free to take the next call. Thus, when an agent is on a call, it halts placing calls until the agent finishes the call and shows availability. Progressive dialer facilitates more customer-centric communications between agents and clients.

What is a predictive dialer?

It predicts when an agent will be free after completing an ongoing call and how many numbers need to be dialed to connect to a real human. Based on the predictive value, the predictive dialer autonomously dials phone numbers concurrently and connects the agent to the customer/prospect that attended the call. It employs an algorithm that slows down and speeds up the dialing rate to decrease the call drop rate and boost agent talk time. It is an effective approach to reach all leads in the shortest time. The predictive dialer is perfect to run large-volume telemarketing campaigns, sales calls, political calls, etc.
