One of the most effective tools inside JustCall’s sales toolkit is its power dialer. Whether you’re managing outbound sales teams, running cold call lists, or conducting follow-up campaigns, this feature helps you reduce idle time, scale outreach, and boost rep efficiency.
If you want your team to make more calls, faster, and with better tracking, learning how to set up a power dialer campaign is a must. Below is a simple step-by-step guide to launching call campaigns using JustCall’s Single Line or Predictive Dialer, along with pro tips to improve conversion outcomes.
Why Use JustCall’s Power Dialer for Outbound Calling?
Traditional manual dialing slows down reps. JustCall’s power dialer automates outbound calls, allowing agents to dial through a list with minimal delay between calls. This means more conversations per hour and fewer missed opportunities.
With features like voicemail drops, call wrap-up time, and CRM integration, your team can work smarter, not harder, when prospecting or re-engaging leads.

Step 1: Upload or Sync Your Call List
Before launching a campaign, you’ll need your list of contacts. JustCall allows you to either upload a CSV file with contact details or sync directly from your CRM, such as HubSpot, Salesforce, or Pipedrive.
Make sure your list includes:
- Full name
- Phone number
- Company (if applicable)
- Tags or notes (e.g., warm lead, webinar attendee)
A clean, segmented list gives your reps context and helps you personalize conversations.
Step 2: Choose Your Dialing Mode
JustCall offers two dialing options:
Single-Line Dialer: Ideal for smaller teams or high-value accounts where personalized one-on-one interactions are crucial.
Predictive Dialer: Best for larger lists and high-volume outbound efforts. This dialer calls multiple numbers simultaneously and routes answered calls to available agents.
Choose the option that aligns with your campaign goals and team structure.
Step 3: Customize Campaign Settings
Before going live, configure your call campaign settings to match your team’s workflow:
Voicemail Drop: Record and upload a standard voicemail message that can be dropped instantly when no one answers. This saves reps from having to repeat themselves all day.
Wrap-Up Time: Allocate seconds or minutes between calls to allow reps to take notes or categorize the outcome.
Call Cadence: Control how quickly numbers are dialed and redialed, based on the number of available agents and the average call time.
This flexibility ensures your campaign flows smoothly without overwhelming or underutilizing your representatives.
Step 4: Assign Reps or Teams
Once the campaign is configured, assign it to individual reps or entire sales teams. Inside JustCall, each user can access their assigned campaigns from the dashboard, making it easy to stay organized and track performance.
This feature is especially helpful if you’re running multiple outbound campaigns by region, product, or lead type.
Step 5: Launch and Monitor Your Campaign
When your list is uploaded, settings are customized, and reps are assigned, it’s time to hit launch.
Inside JustCall, you can monitor campaign performance in real-time. This includes:
- Number of calls made
- Answer rate
- Call duration
- Voicemails left
- Call outcomes logged by reps
Live analytics let you spot trends, identify underperforming campaigns, and optimize as you go.
Use Tags to Trigger Automation and Segment Leads

As your reps complete calls, encourage them to tag each conversation. Useful tags might include:
- Hot Lead
- Left Voicemail
- Follow-Up Needed
- Not Interested
These tags do more than organize your data. When used in combination with JustCall’s Zapier integration, they can trigger workflows like:
- Adding hot leads to an email nurture sequence
- Sending a follow-up SMS or calendar link
- Updating the CRM stage or pipeline status automatically
Using this tagging strategy enhances personalization, accelerates follow-up, and improves your overall lead management process.
