Auto dialer
In computer telephony, an automatic dialler (shortened to an auto-dialler or more simply in context just a dialler, and also known as an outbound dialler) is a computer system that makes outgoing calls from a call centre to customers from call agents based upon a loaded list of contacts. Whereas automatic call distribution (ACD) distributes inbound calls to a call centre amongst its agents, an auto dialler makes outbound calls and comes in several forms.
