An automatic dialer is an electronic device or software system that calls customer telephone numbers automatically from a database of leads. It has the ability to target customers and connect them to an agent or an interactive voice response (IVR).

An auto dialer, also known as a predictive dialer, is a type of automated dialing system commonly used in call centers and sales organizations to automate high-volume outbound calling.

An auto-dialer is a contact center tool that makes the agent's life easier by removing the need for manual dialing. It systematically dials phone numbers and connects the call to the agent if someone picks up their phone.
