What is an Auto Dialer?

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.

It utilizes predictive algorithms and computerized functions to automatically make calls from a contact list, connect answered calls to available agents or sales reps, and perform other dialing tasks.

Auto dialer systems are primarily used for efficient outbound telemarketing and lead generation, though they can also be used for other communication purposes like customer surveys, payment reminders, event promotions, appointment confirmations, emergency broadcasts, etc.

The main benefit of using an auto dialer manual dialing is the increased agent productivity, cost savings, and faster speed in contacting leads and customers. Studies show predictive auto dialers can improve agent productivity by 30-100% versus manual dialing.

They are designed to integrate seamlessly with your existing contact center infrastructure and CRM software.

Cloud-based auto-dialers make it easy to get started quickly without large capital investments in hardware.

How Do Auto Dialers Work?

Auto dialers provide contact centers with the capability to automatically make outbound calls in a structured, efficient, and compliant manner.

Here is an in-depth overview of how modern predictive dialer systems work:

1. Contact List Upload

The first step is uploading your contact list into the auto-dialer system. Most systems allow list uploads via an easy-to-use web interface, integrations with CRMs like Salesforce, or APIs.

Your contact list will typically include phone numbers and associated lead/customer data like name, company, location, previous activity, etc.

Auto dialers have capabilities to validate, normalize, and prepare uploaded contact lists including:

  • Identifying and removing duplicates
  • Correcting invalid phone number formats
  • Flagging existing “do not call” phone numbers
  • Adding relevant geographic information for number ranges

2. Predictive Algorithm Analysis

At the heart of an autodialer is the predictive dialing algorithm that determines the pace of outbound calls. The algorithm factors in variables such as:

  • Number of available agents/sales reps
  • Average handle time for calls
  • Allowable abandoned call rate threshold
  • The average time between calls
  • Busy signal frequency
  • Schedule adherence goals

By analyzing these factors in real-time, the algorithm predicts how many leads can be dialed at once while minimizing instances where an answered call waits without an agent is available.

As agents log in/out for the day or take breaks, the system adjusts the dialing pace accordingly to stay within optimized ranges.

3. Outbound Call Initiation

Based on the predictive algorithm analysis, the auto-dialer system begins automatically dialing outbound calls using VoIP technology to reach leads from the contact list.

The system dials multiple calls in parallel, anticipating a percentage of calls to not be answered. This allows answered calls to be routed to the next available agent without delay.

4. Call Routing and Analytics

When a call gets answered, the auto-dialer quickly detects this and immediately routes the call to the next available agent.

If no agents are available, the dialer can place the call on hold and play interactive voice response (IVR) messages until an agent becomes free.

As calls take place, the dialer tracks and records data like call outcome, duration, wait times, etc. for reporting and analytics.

5. Ongoing Lead Engagement

Beyond initial outbound calls, auto-dialers provide options to schedule follow-up calls at optimal times and frequencies to leads who previously did not answer.

This helps persistently try contacting hard-to-reach leads.

The system can also automatically drop leads that meet a defined threshold of unsuccessful outreach attempts.

Types of Automatic Dialers

While auto-dialers share common underlying approaches, some variations in specific dialing modes impact how they function:

1. Predictive Dialing

This is the most widely used dialing mode in modern auto dialers. As outlined previously, predictive dialing uses algorithms to estimate when agents will finish their calls and become available to receive the next outbound call.

By tracking real-time metrics and agent states, predictive dialers can initiate multiple parallel calls to minimize agents waiting between conversations.

Predictive dialing focuses on maintaining consistent agent productivity and minimizing abandoned calls. It’s preferred for high-volume call campaigns.

2. Progressive Dialing

Progressive dialing combines both predictive and power dialing approaches. It starts in predictive mode but can switch to power dialing when agents are waiting between calls to avoid idle time.

Once agents become busy again, progressive dialers revert to predictive mode. This hybrid approach balances optimal call pacing with keeping agents productive.

3. Power Dialing

Power dialing focuses on attempting to contact leads in a contact list as quickly as possible with less emphasis on pacing and reconnects.

Power dialers work in a rapid linear sequence, minimizing the gap between consecutive call attempts versus predicting availability. This trades off some potential idle time for faster overall list processing.

Power dialing is well-suited for campaigns focused on lead acquisition with very high contact rates and less need for optimal resource utilization.

4. Preview Dialing

Preview dialers provide agents with on-screen lead/customer data a few seconds before calls get connected. This allows them to review relevant info like previous interactions to enhance the conversation experience.

The dialer connects the outbound call once the agent accepts the previewed lead. Preview dialing results in more informed and productive call conversations.

5. Manual Dialing

Manual dialing gives agents full control over outbound calling. Instead of auto-dialed calls, agents manually click numbers to initiate dials.

While productivity is lower, manual dialing allows full agent discretion. It also helps meet stricter compliance needs in certain highly regulated industries.

Benefits of Auto Dialer Software

Auto Dialers Make Your Contact Center More Efficient

Using auto dialer systems in your outbound contact center operations provides significant efficiency benefits:

Increased Agent Productivity

By minimizing the time that agents spend waiting between calls, auto-dialers allow representatives to handle more calls per shift. Increased calls handled directly translate into higher agent productivity.

Studies have found predictive auto dialers can increase productivity by 30-100% versus manual dialing. Instead of manually dialing and waiting for leads to answer, agents talk almost continuously throughout their shift.

Reduced Idle Time

Idle time, where agents wait between calls, is minimized through predictive algorithms. By initiating multiple parallel outbound calls, answered calls can be immediately routed to agents as they become available.

This keeps agents engaged in conversations versus waiting through periods of silence. Contact rates accelerate with near-continuous agent activity.

More Calls Handled Per Hour

With agents maximized and idle time reduced, call centers can handle exponentially more outbound calls using auto-dialers.

Instead of manually dialing a few dozen calls per hour, agents can engage with hundreds of leads through automation and predictive capabilities.

Improved Lead and Customer Reach

The increased calls per hour enabled by auto-dialers significantly expand customer reach. Large lead lists and contact databases can be processed in a fraction of the time versus manual efforts.

Hard-to-reach customers are engaged through persistent dialing and scheduled follow-up call attempts. More conversations drive better business results.

Faster Campaign Execution

The compound impact of reduced idle time, increased agent productivity, and higher call capacity is that campaigns get completed much faster.

What once took weeks of manual dialing to work through can now be accomplished with an autodialer in days or hours. Campaigns scale efficiently.

Detailed Analytics and Reporting

Auto dialers track extensive real-time telemetry on campaign performance, agent activity, and call outcomes. Detailed monitoring, results reporting, and data exports help optimize your outbound operations.

By analyzing trends in the provided analytics, campaigns can be fine-tuned to increase contacts and desired call outcomes.

Improved Compliance and Governance

Auto dialers provide visibility into adherence with regional calling regulations, DNC lists, and internal governance policies through detailed reporting and analytics.

Oversight capabilities reduce compliance issues and risks that may otherwise occur with purely manual calling.

Enhanced Customer Experiences

The structured pacing, informed agents, and voice prompts enabled by auto-dialers help improve customer call experiences. Predictive algorithms make the conversations feel naturally spaced.
