Open-source predictive dialer for your call center save time and free up your agents to handle a larger volume of calls and engage with potential leads that much faster.

An example of such technological advancement is predictive dialing. Predictive dialer help in improving the productivity of your call center by increasing the utilization of the agents’ idle time by 92% which in turn shoots up the productivity by 200-300%.

What is a Predictive Dialer?

A predictive dialer is sort of an auto dialer that uses statistical analysis to predict and place calls even before a sales agent is free to make the call. It is unlike other auto dialer that place calls only once the agent is free. 

In other words, an auto dialer simply places calls one after the other. A predictive dialer, on the other hand, uses algorithms and even machine learning techniques to reduce agent downtime. It dials multiple numbers at a time and connects the agent to the call that has been answered. In this way, agents do not have to waste time while waiting for a call to be answered. Instead, they already have an active call queued up for them as they conclude the current call.

For instance, the predictive dialer system detects that only 40% of calls are being answered by leads on a particular day and the average time of agents on each call is 300 seconds. Now if the customers are taking 10 seconds on an average to pick up calls, then the system automatically dials numbers for an agent at the 290-second mark to save 10 seconds of the agent’s time.

How Do Predictive Dialer Work?

As the name suggests, predictive dialer software uses algorithms and formulas to predict when the agent will be able to receive the next customer on call. The predictive dialer software also dials phone numbers on the agent’s behalf to save the time that agents would otherwise spend dialing numbers manually.

The dialer makes these assumptions based on the patterns observed in previous calls such as how long it takes on an average for a customer to answer a call, typical call duration, etc. In this way, agents have a steady stream of calls for them. 

A basic predictive dialer has the following components – 

  1. List management software (often integrated with a CRM solution) to determine which numbers to call 
  2. Admin software that helps in managing agents
  3. Software to determine how the call progresses (For example, no answer, a busy signal, etc.)
  4. Algorithm to determine how much to dial and when to dial
  5. Inbuilt reporting

The predictive dialer goes through the list of contacts to determine how many calls should be assigned per agent. This is called the Concurrent Call Ratio. Some of the metrics used to determine this ratio are real-time hit rate, number of available agents, average time per call, number of contacts, etc. 

Who Uses Predictive Dialers?

Predictive dialer were initially used for debt collection or to increase customer engagement. Predictive dialer systems started off as a hardware solution but later evolved into open-source software solutions which are offered by many vendors today.

Many companies prefer open-source predictive dialer to minimize infrastructure and upfront costs. Some of these predictive dialer software programs even come integrated with CRM software. They provide insights based on various call metrics. 

Currently, many companies use open-source predictive dialer for market research, telemarketing, customer service follow-ups, etc. Some companies also use these dialer to maximize the time spent on the phone for nurturing leads. 

How Effective Are Predictive Dialers?

Since predictive dialer help you save a lot of time, they are very effective. For instance, let’s say that typing a number manually takes 30 seconds per agent and each agent has a target of 100 calls per day. Each call takes about 3 minutes. Based on these numbers, each agent spends about 50 minutes each day just typing numbers. The predictive dialer can help save this time for better agent utilization. 

This helps increase the overall efficiency of the call center thereby improving customer experience. With the help of a predictive dialer, you will also be using your resources to their maximum potential.

The only downside of open-source predictive dialer is that they don’t leave any time gap for agents to research the leads between calls. Hence, they may not be as effective for companies selling high-value items or companies looking to create a stellar customer experience.
