How to Create WhatsApp Voice Call Campaigns
If you've been looking for a way to automatically call your customers at scale through WhatsApp, DoubleTick's new Voice Call Campaign feature is exactly what you need. This guide walks you through the entire setup — from uploading your customer list to confirming and launching your campaign.
Step 1: Upload Your Customer Data
Before creating a campaign, you need your customer list ready in DoubleTick.
Go to the Customer section and click on Import. Your spreadsheet should have at minimum two columns — Name and Phone Number. During the import, you'll be asked to map fields like custom fields, WhatsApp mapping, agent mapping, and tags.
Once uploaded, your list will appear and be ready to use as a segment in your campaign.
Step 2: Create a New Voice Campaign
Navigate to the Voice Calls section and click Create Campaign. A "New voice campaign" dialog will open where you fill in all the key settings.
Campaign Name
Give your campaign a clear, descriptive name — something like "AI Voice – Jewelry Customers – 25 May" so you can easily identify it later.
Calling Method
Currently, WhatsApp Calling is the only available method. It uses free voice calls over a WhatsApp channel. More calling methods are coming soon.
Segment
Select the customer list you want to call. This can be a newly uploaded list or any previously created segment in DoubleTick.
AI Voice Agent
Choose which AI voice agent will be handling these calls. This is the bot that will speak to your customers when they pick up.
Calling Window
Set the time range during which the system is allowed to make and retry calls — for example, 10:00 to 19:00. All call attempts, including retries, will strictly happen within this window.
This matters for two reasons:
Compliance — Many industries have regulations around when customers can be contacted.
Business hours — You don't want automated calls going out outside your working hours.
Parallel Calls
This controls how many calls can be dialed simultaneously at any given moment. You can choose from preset values — 1, 5, 10, 25, or 50 — or set a custom number using the + and – buttons.
⚠️ Important: Parallel calls (concurrency) is fixed at the time you create the campaign and cannot be changed later. Choose this number carefully.
Here's a simple way to think about it: if you have 1 lakh (100,000) contacts and a 9-hour calling window, you need to dial roughly 11,000 calls per hour. If the average call lasts about 2 minutes, you'd need around 4,000 concurrent channels. The larger your list and the shorter your window, the higher you'll want to set this number.

Select which WhatsApp number or channel the calls should go out from
Once all fields are filled, click Review to proceed.
Step 3: Review and Confirm
The Review and confirm screen gives you a full summary of your campaign before it goes live. You'll see four tiles:
Voice Agent — the AI agent assigned to the campaign
Calling Method — WhatsApp Calling and the channel selected
Calling Window — the time range you set, shown in local time
Parallel Calls — the concurrency number, with a reminder that it's fixed at create time
Take a moment to double-check everything here. If something looks wrong, click Back to go and fix it.
Step 4: Choose When to Send
At the bottom of the review screen, you'll see the option "Send this campaign from" with two choices:
Start now — The campaign begins immediately after you confirm.
Schedule for later — A date and time picker appears where you can set a future launch date and time. The Confirm and start button will remain greyed out until you pick a valid date and time.
Once you're happy with everything, click Confirm and start to launch your campaign.
