Important: You must have WhatsApp enabled to access the voice calling options (WhatsApp Calling). If WhatsApp is enabled for your account, these options will be available automatically. Check your plan to verify whether this feature is included.

It is now possible to make voice calls in Customer Service, allowing companies to place calls directly through conversation flows.

Receive a WhatsApp Call

To receive a WhatsApp call from your customer:

  1. Go to Zenvia Customer Cloud > Customer Service > Inbox.
  2. In an open conversation, click the phone icon on the right side and select Receive a WhatsApp call.

A message called Send invitation to call will be displayed. If you are ready, click Confirm. Otherwise, click Cancel.

After clicking Confirm, the customer receives the following WhatsApp message:

“We can provide this service through a voice call. Click the button below whenever you want to start the call.”

Along with the Start Call button.

You will then see the message Receiving a WhatsApp voice call, where you can:

  • Answer the call (green phone icon);
  • Decline the call (red phone icon);
  • Mute the call or hang up at any time.

💡 Tips:  A company can send a maximum of:

  • 1 permission request every 24 hours;
  • 2 permission requests within a 7-day period.

This limit is reset whenever a connected call takes place between the company and the customer.

The permission request expires in the following situations:

  • After a connected call between the company and the customer;
  • When the customer grants permission;
  • 72 hours after the permission has been accepted or declined;
  • 72 hours after the request is sent if the customer does not respond.

Done! Now you know how to enable WhatsApp voice calls in Customer Service.
