Features Educate Predictive dialer

Predictive dialer

Use real-time data to increase your outreach by dialing multiple numbers at once.

Predictive dialing is an automated outbound calling method that uses real-time statistics to dial multiple phone numbers simultaneously and connect answered calls to free agents.

The purpose of the predictive dialer is to minimize the time spent waiting between active calls. The method makes it possible to make calls 'in the background' and by that reduce idle time and increase the amount of time agents spend speaking with prospects. The system simply minimizes the gaps between calls, so that the agents spend more time talking and less time preparing for the next call.

The dialer uses algorithms that track average talk time, the number of available agents, the number of missed calls, etc., to predict how many calls are likely to be answered, how long current conversations will last, and when agents will become available.

When a person answers, the system immediately routes the call to a free agent. If no agent is available at that exact moment, the system may briefly hold the call, disconnect it, or schedule it for a later attempt.

Compared to manual dialing, where agents place each call themselves, predictive dialing automates the process entirely. Unlike power/progressive dialing, which typically places one call per available agent at a time, predictive dialing places multiple calls in advance and relies on statistical modeling to maintain a continuous flow of live conversations.

When is predictive dialing useful?

Predictive dialing is particularly useful for high-volume outbound campaigns and is most commonly used in contact centers, fundraising, and sales departments with a streamlined outbound outreach setup.

Because the dialing is based on real-time data, it works better the more agents are on the line. We recommend at least 5 agents online simultaneously to avoid errors and achieve the most effective results.

How to prevent errors when using a predictive dialer

Even though the system uses real-time statistics to predict how many calls are likely to be answered, errors can occur if it is not properly tuned or there are too few agents online.

This may occasionally cause a short delay before an agent begins speaking, or, worse, a call is answered but no agent is available to take it, resulting in so-called dropped calls.

For this reason, its use is regulated in many countries, often with limits on acceptable abandoned call rates, e.g., in Great Britain.

To prevent this, it is ultimately about finding the right balance between streamlining and minimizing dropped calls, even though our predictive dialer constantly adjusts the dial rate based on settings and behavior.

Check local regulations

It is a good idea to check local regulations regarding the number of dropped calls tolerated before activating predictive dialing to ensure compliance.

Anyhow, it is always good practice not to be too aggressive when using predictive dialing and to continuously keep monitoring the outcome of the calls in order to adjust the settings to avoid errors or high drop call rates.

Predictive dial rate 

The dial rate specifies the number of active calls requested per active agent. A dial rate of 1.0 indicates that the system must have the same number of active calls as agents.

The higher the dial rate, the lower the wait time for agents between calls, but at the same time, the number of calls that can't be answered will, inevitably, be higher.

If you experience too many dropped or abandoned calls, you may need to lower the dial rate, especially when making or selling fundraising calls. It may be intimidating for the lead to receive a ghost call. Worst case, you’ll miss an opportunity.

How to analyze your predictive dialing set up

In Adversus, you can track all data parameters that affect the predictive dialer.

By digging into these data, it’s possible to adjust the dialer accordingly, e.g., based on the number of agents currently in an active call, the number of leads being called, the average waiting time, the contact rate, the drop rate, and the number of failed calls. Adversus measures activity within the last 5 minutes. 

Current contact rate
Out of all calls placed, what percentage pick up the phone?

Current AMD rate
Out of all calls placed, what percentage has the Answering Machine Detection discarded?

Current drop rate
Specifies how many calls are dropped, e.g., a lead picks up, but there is no available agent to take the call.

Recently failed calls
Tells you how many calls failed when dialing, e.g., due to an invalid number or incorrect formatting. 

 

Auto dial threshold
The auto dial threshold specifies the maximum dial rate per available agent. This is to ensure that the predictive algorithm does not initiate an unrealistically high number of calls. Normally, we recommend using the decimal range 2, but where to put it also depends on how many agents are online and the outcome.

Instead of adjusting the dial rate threshold, it can sometimes be more useful to adjust the  Intensity dial level: how quickly you want the dialer to react. You can either make it faster or slower, e.g., so the dial rate adjusts upwards faster when there are available agents, but adjusts downwards more slowly when the number of agents decreases, or vice versa.

Avoid dropped calls

Are you struggling with having too many dropped calls? You need to adjust the adaptive drop rate limit that specifies the percentage of dropped calls allowed. You can also adjust the Maximum dial time, which is the maximum number of seconds allowed to pass before a call is dropped if an agent does not answer, typically in situations where there are too few agents online.

Finally, adjusting the Maximum ring time for how long the predictive dialer tries to call a lead before saving it as ‘Not answered’ can help prevent dropped calls, but is more likely to be used if you want to optimize the number of calls pr.

Combining predictive dialing with inbound calling

At Adversus, we’ve made it mandatory to use inbound for all outbound campaigns, not only for compliance reasons, but also because we believe it is best practice to be transparent when calling. It allows the lead to identify the callee because it’s possible to call back any given phone number.
