With a WhatsApp Cloud inbox you can receive and place voice calls directly from HellouOne, nothing to install: audio runs through your browser.
Requirements
- WhatsApp inbox connected through WhatsApp Cloud (Meta's official API).
- Calling enabled for your account and for the inbox (see Configure calling on your inbox).
- Microphone access allowed in the browser (Chrome or Edge recommended).
Receive a call
- When a customer calls, a floating window shows their name/number.
- Click Answer. The call opens inside the contact's conversation.
- When you're done, click Hang up. The call is logged in the conversation with its duration.
Call a customer
- Open the contact's conversation and click the phone icon.
- If the customer hasn't authorized calls yet, WhatsApp sends them a permission request; once they accept, you can call.
Calls can only be started with customers who already have an active WhatsApp conversation with you.
