An autodialer is a software program that automatically dials telephone numbers from a list or a database.
Autodialers may be configured to perform various tasks, including:
- Leaving voice messages.
- Transferring the call to the first available agent.
- Enabling interaction with the called party through voice or keypad response.
A related type of application known as a predictive dialer automatically calls a list of telephone numbers in sequence, screening out no-answers, busy signals, answering machines and disconnected numbers while predicting at what point a human will be available to handle the next call. Both autodialers and predictive dialers are often used in call centers.
An autodialed call that leaves a prerecorded message is sometimes known as a robocall.
