WhatsApp Business Voice: Everything You Need to Know

What is WhatsApp Business Voice?

WhatsApp Business Voice enables businesses to make voice calls directly through the WhatsApp Business Platform. It extends the traditional text-based interaction on WhatsApp to real-time voice communication, allowing brands to talk to customers personally—without needing a separate phone line or app.

It combines the reliability of WhatsApp with the familiarity of a phone call.

How It Works

WhatsApp Business Calling launched in July 2025 and features the following:

• Agents initiate voice calls via the WhatsApp interface.
• Calls are VoIP-based, using the internet, not traditional telecom lines.
• Customers receive the call through their regular WhatsApp app.
• Audio quality is optimized for low bandwidth settings.

You must have:

• An approved WhatsApp Business API account.
• A verified phone number.
• A voice-enabled setup via a provider or BSP (Business Solution Provider) like HelloDuty
