Parallel Dialer: Reach more prospects in record time
Make 4 times more calls in less time with our easy-to-use parallel dialer. Engage with prospects faster and optimize your call performance.

Elevate your team’s success
Maximize your sales reps’ efficiency with faster prospecting.
Boost pick-up rates
Connect with more leads to close new deals.
Save time while prospecting
Call multiple numbers at once and reach more prospects in less time.

What is a parallel dialer?
A parallel dialer allows an agent to call multiple contacts at once. When a contact answers, the other calls end automatically. This prevents dead air (the silence between when the contact picks up and when the agent is connected) and reduces call abandonment, ensuring a seamless call experience.
Sales teams use parallel dialers to boost efficiency and reach more prospects. This method works best for agents with a set call list and specific goals.
Spend less time dialing and more time connecting with prospects

Connect with more prospects, faster
Stop dialing manually and start connecting instantly. The parallel dialer saves you valuable time by automatically dialing multiple numbers at once, helping you optimize your productivity and minimize your downtime.

Maximize your outreach
With the Ringover parallel dialer, you call up to 4x faster and handle more conversations in less time. By dialing multiple numbers at once and connecting only when a prospect picks up, you improve your pick-up rate and stay focused on closing deals.

Drive team success
The parallel dialer’s intuitive design allows your agents to spend more time creating meaningful conversations and less time performing manual tasks. With streamlined calling, your team is able to connect with more prospects and quickly meet their targets.

What is a parallel dialer?
A parallel dialer (or parallel dialer) is an automatic dialing tool that allows agents to make multiple calls simultaneously to different numbers from a contact list. Unlike other types of automatic dialers, such as a power dialer (which dials one number per agent) or a predictive dialer (which uses algorithms to anticipate agent availability), the parallel dialer dials several numbers at the same time and connects the agent with the first person who answers.
What is parallel calling?
Parallel calling is a dialing strategy used in call centers and sales teams to optimize agents’ time and improve the contact rate with customers. Instead of dialing one number after another sequentially, the system makes multiple calls simultaneously to different contacts. This minimizes wait time between interactions and increases operational efficiency by connecting agents only with calls answered by real people.
This method is especially useful for teams handling large call volumes, as it reduces the number of failed attempts by automatically filtering out busy numbers, voicemails, or unanswered calls. Additionally, some parallel dialing systems include algorithms that dynamically adjust the call pace based on agent availability and customer response rate, ensuring a balance between efficiency and quality in communication.
How to make multiple calls?
To make multiple calls and have several conversations at the same time, the Parallel Dialer functionality from Ringover is an efficient and practical solution. This tool allows agents to make multiple calls simultaneously without the need to manually dial each number. Once a customer answers, the other calls are automatically dropped.
By using a parallel dialer, sales or customer service teams can handle two or more calls at the same time, improving productivity and reducing downtime between interactions. The ability to make multiple calls simultaneously means that agents won’t miss contact opportunities and can manage more customers efficiently.
How do parallel dialers work?
A parallel dialer works by dialing several phone numbers at the same time and connecting an agent with the first recipient who answers. Its goal is to reduce waiting times between calls and improve the productivity of sales and customer service teams.
Unlike other dialing systems, such as power dialers or predictive dialers, the parallel dialer makes multiple calls simultaneously without relying on predictive algorithms, ensuring fast and constant contact. For a parallel dialer to function well, the following steps should be followed:
- Contact list upload – A database with the numbers to call is imported.
- Simultaneous dialing – The system dials multiple numbers at once to maximize connection rates.
- Response detection – When a recipient answers, the rest of the ongoing parallel calls are disconnected.
- Management of failed calls – If a number doesn’t answer, is busy, or goes to voicemail, the system records it and can reschedule another attempt later.
- Interaction logging – Each call is stored in a CRM or database, allowing efficient tracking of customers or prospects.
What is a predictive call?
A predictive call is a call made through a predictive dialer, an automated system that uses algorithms to dial multiple numbers simultaneously and connect agents only with calls answered by a person. Its goal is to reduce waiting times between calls and maximize the productivity of sales or customer service teams.
How does a predictive dialer work?
A predictive dialer works through an automated system that dials multiple numbers simultaneously and uses advanced algorithms to connect agents only with calls answered by a person. Its goal is to reduce waiting time between interactions and increase efficiency in call management. The key steps for proper functioning are:
- Contact database upload – A list of phone numbers is entered into the predictive dialer system.
- Availability analysis and call pattern recognition – The system analyzes historical data, response rates, and the number of available agents to predict when to make calls.
- Simultaneous and batch dialing – Multiple calls are made at the same time, exceeding the number of available agents, based on response probability.
- Automatic filtering of unhelpful calls – The system detects and discards unanswered calls, busy numbers, voicemails, or disconnected lines.
- Routing effective calls to agents – Only calls answered by real people are routed to available agents in real-time.
- Dynamic dialing speed adjustment – The dialer constantly monitors response rates and agent availability to adjust dialing speed and prevent long wait times or unattended calls.
- Data logging and analysis – Statistics are collected on call effectiveness, allowing contact strategies to be optimized and team productivity to improve.
Unlike other dialing systems, such as power dialers or predictive dialers, the parallel dialer makes multiple calls simultaneously without relying on predictive algorithms, ensuring fast and constant contact. For a parallel dialer to function well, the following steps should be followed.
