Auto Dialer

What does auto dialer mean?

An auto dialer is a telephony solution used to automate the process of dialing telephone numbers from a predefined list, often used in outbound call centers. Once a call is answered, the system connects the respondent to a live agent or plays a pre-recorded message. It eliminates manual dialing — in turn reducing agent idle time and optimizing call center operations.   

There are many types of auto-dialers. 

• Preview dialer: Let agents review caller details before deciding to dial. 
• Progressive dialer: Dials the next number automatically after a call ends. 
• Predictive dialer: Dials multiple numbers at once, anticipating when agents will be free. 
• Power dialer: Dials one number at a time, immediately moving to the next after a call. 
• Robo dialer: Sends out pre-recorded messages automatically, without needing an agent. 

Now that you understand what an auto dialer is, let’s jump into how it functions.  

How does a typical auto dialer work?  

Here is a concise and technical breakdown of how an auto dialer works: 

• Number retrieval: Auto dialer software selects numbers from a list, programmed to handle responses like busy signals, live responses or voicemails. 
• Dialing: Systematically dials using VoIP or voice modems to transmit calls. 
• Connection detection: Voice recognition technology identifies whether a live person or voicemail answers. 
• Routing: Live responses are immediately routed to available agents; voicemails may trigger a retry later. 
• Message delivery: For no agent available or specific campaigns, a pre-recorded message is played. 
• Data collection: Collects data on call outcomes, duration and response rates for analysis and optimization.
