Get Started with WhatsApp Voice Calling and WhatsApp Voice Chatbot

Conversations Just Got Real — Introducing WhatsApp Voice by MSG91

Let’s face it — when things get complicated, nothing beats a quick voice call. While WhatsApp has transformed business messaging, voice support was the missing piece.

Now, MSG91 is bringing WhatsApp Voice Calling to the table — but not just as another feature. It's thoughtfully designed to meet real business needs, making customer support faster, more personal, and more efficient.

WhatsApp Voice Calling is a feature that allows users to make voice calls over the internet using WhatsApp, rather than using traditional phone networks.

What’s New with WhatsApp Voice Calling? And Why Does It Matter?

Picture this: a customer is trying to explain a technical issue or a product defect. Messages are going back and forth, but it’s taking way too long. They just want to talk to someone — right now.

With WhatsApp Voice via MSG91, they can.

Customers can now place a voice call directly from their WhatsApp chat window — and your agents/ customer support executives gets the call on your Hello Application. No app switching, no delays. Just faster resolutions and smoother conversations.

Here’s how it works, and why it’s built for businesses like yours:

How Can I Start Using WhatsApp Voice Calling with MSG91?

To use WhatsApp Voice Calling for your business, you need to meet just three basic conditions:

1. Your WhatsApp Number Must Be on MSG91 and Your Number Must Be Approved for 1000+ Messages Per Day

This is the starting point. To activate WhatsApp Voice, your number needs to be:

• Your number must be connected to MSG91’s WhatsApp Business API.

• Approved by WhatsApp (Meta) to send at least 1,000 messages per day.

2. Customers Must Message You First to Unlock the Call Option

Calls aren’t open to everyone. The call option only appears for the customer after they’ve sent you a message on WhatsApp.

Why? Because this keeps the experience respectful. It puts control in the customer’s hands. No spammy outbound calls. No awkward cold calls. Just a smooth escalation from chat to call — when the customer decides it’s necessary.

Step to Enable WhatsApp Voice Calling Button:

1. Once all the above conditions are met -Enable the WhatsApp Voice Call Button on your WhatsApp Business Number with the help of this API: https://docs.msg91.com/whatsapp/whatsapp-voice-call

The button will be shown in 15 minutes on your number..

Now you have WhatsApp Inbound/Outbound Calls

On WhatsApp, inbound and outbound calling are both possible.

Customers must call you first — only then can you call them back(outbound).

This means you cannot initiate outbound calls on your own.

The control stays with your customers, ensuring calls happen only when relevant.

Your team, in turn, stays ready to respond instantly.
