What is a Predictive Dialer?

What is a predictive dialer
and how it boosts call center productivity?

Voiptime cloud-based predictive dialing system automates the dialing flow, by using an intelligent algorithm to dramatically increase dialing rate and improve call center performance.

Predictive dialer calls multiple numbers from a contact list simultaneously. Due to the ability to skip over busy signals, disconnected numbers, unanswered calls, and voicemails, it increases the outbound call center efficiency. Our intelligent outbound call center software evaluates the agent’s availability and adjusts the dialing pace accordingly, that allows keeping the balance between the required agent workload and the allowed abandon call rate.

What is the difference
between predictive and progressive dialers?

Both dialing modes can be called autodialers, however, a professional will always be able to separate between them.

Automatically and simultaneously initiates multiple outgoing calls from the contact list and routes the answered calls to the agents;

Uses a statistical algorithm to determine the agent availability, minimize the agent idle time while constantly controlling the required dialing rate to reduce the likelihood of lost calls;

Usually used for B2C calling processes.

The number of calls depends on the call receiving capability of the agents;

Makes outgoing calls sequentially when the agent is available ready to handle the next call;

Usually used for B2B calling processes.

How does a predictive dialer work?

The principles behind predictive dialing logic are the following:


The dialer software starts by dialing a number from the list. Based on statistics (average handle time, after-call work, percentage of answered calls, abandon call rate, etc.), it predicts how many entries should be dialed per operator to maximize their workload.


The dialer recognizes no answers, busy signals, answering machines, filters them out, and connects agents with live calls. All unsuccessful dialing attempts will be processed by the system automatically according to the preset redialing intervals.


Using the algorithm and collected statistics on previous call attempts, the dialer predicts the approximate time when an agent becomes available and dials the next number.


Based on the collected statistics, contact rate and percentage of abandoned calls, it calculates the required dialing rate.

Predictive dialer implementation

There are several critical factors to consider when implementing predictive dialing software in a call center.

Predictive Dialer Complete Guide | Voiptime Cloud


Prior to purchasing an auto dialer, make sure it is compatible with your existing systems. It also must have integration capabilities. Discuss your integration requirements with our managers, and we will offer you the best option for their implementation.

Predictive Dialer Complete Guide | Voiptime Cloud


This factor is essential if you run a seasonal business or if you plan to expand your company in the future. Prior to making a purchase, check out how a dialer handles large call volumes, behaves after modifications, and easily and quickly allows you to add new operators.

Predictive Dialer Complete Guide | Voiptime Cloud

Contact lists and contact center size

For businesses, this is a critical factor when choosing dialing modes of call center software. Predictive dialing mode works even for a small team, for example, with 5+ agents, thus helping to reduce agent downtime. This mode is the preferred choice for improving agent efficiency in mid-sized call centers, when working with large campaigns. Moreover, predictive dialing should not be used for high ticket size deals & high-value prospects as those scenarios call for more personalized outreach.

Predictive Dialer Complete Guide | Voiptime Cloud

Type of the target audience (B2B or B2C)

Usually, B2B call centers requires a sophisticated sales approach to get ahead of the competition, and moving to a progressive dialer would be a good choice. Predictive mode works best in B2C campaigns. They should not be used for high ticket size deals & high-value prospects as those scenarios call for more personalized outreach.

Current calling process

It is necessary to implement different types of dialer software for all processes for outbound telemarketing. With a low number of calls for tracking hot leads to close deals or a high-profile process for gathering information, predictive dialing will be most appropriate.

Predictive dialers KPI metrics

An efficient autodialer influences key performance indicators (KPI) of a call center. Below are the performance metrics that can be improved with the implementation of the dialing software.

Predictive Dialer Complete Guide | Voiptime Cloud

ACR (Abandoned Call Ratio)

ACR is an arithmetic estimation of the number of lost calls (abandoned by the prospect) while waiting for a connection with an agent in the queue. The abandoned call ratio is regulated by law, and typically, should not exceed 3% for every 30 days (5% for Canada). The predictive dialer monitors the maximum abandoned call rate and reduces call pacing rate if necessary.

Predictive Dialer Complete Guide | Voiptime Cloud

AAD (Average Answer Delay)

AAD is the average amount of time that a prospect waits before hanging up when there’s no answer from an agent during an outbound call. Provided that you have enough agents, this dialer will connect prospects with agents immediately, which will significantly minimize delays.

Predictive Dialer Complete Guide | Voiptime Cloud

ASR (Average Seizure Ratio)

This is a percentage of successfully answered calls from total dialing attempts (“seizures”). To calculate ASR, divide successfully answered calls by the total number of dialing attempts and multiply by 100. High ASR (60% and above) indicates a reliable network and high-quality customer service.

Predictive Dialer Complete Guide | Voiptime Cloud

ACD (Average Call Duration)

ACD is the length of an actual conversation between an agent and the customer. It is the talking time without pre-call preparation or post-call documentation. To calculate ACD, divide the duration of all answered calls by the total number of answered calls.

Predictive Dialer Complete Guide | Voiptime Cloud

User Occupancy

User occupancy or agent occupancy is the percentage of time an agent spends handling calls versus waiting for calls to arrive (idle time). User occupancy is calculated by dividing actual working hours by staff hours. Predictive dialer reduces the wait time between calls, which increases agent occupancy up to 80%.

Predictive Dialer Complete Guide | Voiptime Cloud

Average Wait Time

This is the amount of time a customer waits in a queue until one’s issue is addressed by a contact center representative. Average wait time in outbound campaigns is considered an important dialing optimization factor used to minimize the agent’s idle time between calls and reduce answer delays. This metric is also regulated by law; typically, it should not exceed 2 seconds.

How does a predictive dialer know the difference between a human voice and an answering machine?-

The technology that underlies the predictive dialing algorithm is answering machine detection (AMD).

To tell a human from an answering machine, the predictive software uses the following voice recognition techniques:

  • detecting a real person by hearing “Hello” followed by a short pause;
  • detecting a long sequence of words without pauses, e.g. “Hello, I’m not at home right now, please leave a message…”.

This technology is not perfect. It can make mistakes and disconnect a live call. To avoid a possible increase in abandoned calls, some vendors enable agents to switch off the AMD feature and let them decide whether they are talking to an answering machine or a real person. However, this approach is not generally practiced in outbound call center dialers as it decreases the overall efficiency.

Can predictive dialers work with skype?+

Some vendors offer dialers that utilize the outbound calling features of Skype. Although it is possible to use Skype for predictive dialing, it is not generally recommended since such dialer solutions work best with VOIP protocols. The main disadvantages of Skype predictive dialing are long initial response time and low audio quality.

What is a smart predictive dialer?+

These are regular dialers with extra functionality. Smart predictive dialers play pre-recorded voice messages to all callees from the list, automatically receive input from a called person, and continue based on their actions without human intervention.

Such dialers call the numbers from the uploaded list, play a short, pre-recorded message to each person, and ask them to press a particular key if they wish to speak to a live agent to learn more. This approach to sales is more targeted. It is based on the “pull” rather than “push” strategy, which can potentially lead to better results.

Is it possible to make a predictive outbound dialer in-house?+

You can build your own custom-made predictive dialing solution provided you possess the narrow industry-specific knowledge, have vast experience working with IP telephony, employ several talented software engineers, and have the necessary hardware. However, this process has its drawbacks:

  • coding, testing and making updates is a timely process;
  • testing requires large volumes of data, and not every company is able to provide that;
  • support can be carried out only by highly skilled specialists, etc.

In most cases, it is much faster and more affordable to seek expert help or purchase a ready-made solution.

Disadvantages of predictive dialing+

  • Many countries impose strict legal regulations on outbound calling. If a chosen dialing software does not have corresponding features, it is strongly recommended to consult an attorney regarding the rules and regulations in a particular region and plan outbound campaigns accordingly.
  • In some cases, the short call delay in 1-2 seconds occurs between the moment when the callee picks up the phone and the connection with the agent. It’s important to watch these indicators because the abandoned call rate is also regulated by law. Voiptime Contact Center solution allows attaching the pre-recorded message that should be played to the contact if the call was put into a call queue (according to UK Ofcom regulations).
  • A predictive dialer doesn’t allow your agents to prioritize leads. They see information on the lead only when a connection is established. It is not enough when a salesperson needs more time to get familiar with this information - for instance, when they sell high-ticket items.
  • This dialer is less efficient for small teams. At least 5+ agents are needed for the predictive algorithm to function properly and accurately.
  • It is recommended not to mix campaigns in different dialing modes for one group of agents. In that case, a predictive dialing system will keep the appropriate workload for your agents.
