What is a Parallel Dialer?

A Parallel Dialer is software that enables multiple outbound calls to be made at the same time. It is ideal for sales teams who need to make many calls as it distributes them evenly among agents. The objective is to enhance productivity and efficiency in the sales process.

How Parallel Dialing Works

Parallel dialing refers to software that initiates multiple outbound calls to prospects simultaneously. In contrast to manually calling one number at a time via telephone, parallel dialing software enables users to call up to ten phone numbers at the same time.

Step One: Research

To get started with parallel dialing, the first step is researching and creating a list of phone numbers to call. Using efficient software that can handle multiple calls simultaneously will save time and improve productivity. Remember to consider factors like call volume, quality, and customer experience for successful parallel dialing.

Step Two: Parallel Dialing

Maximize sales rep efficiency and connection rates with parallel dialing. This method makes simultaneous outbound calls, skipping voicemails and busy signals for optimal outreach. Choose the best option for your business needs between parallel and power dialers.

Top Parallel Dialers

In today's hyper-competitive market, it's crucial to have the right tools for outbound calling that will streamline your process and maximize efficiency. Among these tools, parallel dialers and power dialers have proven themselves game-changers. Parallel dialers can provide a noteworthy edge, and the following brands effectively demonstrate its benefits:

With's intelligent sorting feature, prioritization of calls becomes effortless, ensuring that high-potential leads are reached faster. Similarly, Orum's AI-powered voicemail skip feature cuts down on time spent on unanswered calls, a feature that isn't as optimized in power dialers.

MonsterConnect takes this a step further with its Team Dialing functionality. It enables multiple leads to be dialed simultaneously, but it uniquely provides a collaborative environment where sales reps can work together, maximizing the use of time and energy. Also, MonsterConnect's comprehensive analytics feature allows sales leaders to dissect their team's performance and identify areas for improvement, thereby improving sales strategies.

Comparison of Parallel and Power Dialers

Power dialers dial one number at a time and only move to the next once the current call is finished. While this sequential approach might seem methodical, it doesn't parallel (no pun intended) the efficiency of parallel dialers in high-volume calling situations.

However, these prominent brands offer robust solutions for outbound calling:

Dialpad and PhoneBurner both offer excellent call tracking and recording features, but the time efficiency might be compromised when compared to parallel dialers. JustCall's power dialer, for instance, excels in individual call handling, but might not offer the same level of productivity as MonsterConnect's parallel dialer when dealing with large call volumes.

Key Differences of Power and Parallel Dialers

Power dialers enhance call volume with automatic call distribution and screen for voicemails and busy signals. However, they operate sequentially, dialing one number at a time and moving to the next once the current call is completed. On the other hand, parallel dialers bolster productivity with simultaneous dialing, connecting reps only when a live person answers. This minimizes time spent on unproductive calls. Although this approach may bypass potential opportunities such as voicemails, it allows reps to prioritize live interactions with leads.

Frequently Asked Questions

What are the types of dialer?

There are two main types of dialers: parallel and power. While parallel dialers connect agents with the first person who answers multiple calls simultaneously, power dialers make sequential calls and only connect agents to live answers, boosting productivity. Other dialer options include predictive, preview, and progressive.

How do I choose a good parallel dialer?

When selecting a parallel dialer, consider the features that align with your business requirements and team size. Check if the dialer integrates with your existing software and read reviews before investing. Price comparisons can also help in making an informed decision.


In conclusion, the decision between parallel and power dialers hinges on your business needs. While power dialers offer methodical outreach, parallel dialers prioritize efficiency in high-volume calling scenarios. Brands like, Orum, and MonsterConnect have revolutionized parallel dialing with features that maximize productivity. Power dialers like JustCall, PhoneBurner, and Dialpad provide solid alternatives with robust tracking features. However, for quicker connections with live prospects, parallel dialers often hold the upper hand. Consider your unique business needs, explore your options, and select the dialer that best suits your sales team.
