WhatsApp voice calls have made customer communication more seamless, enabling businesses and customers to connect in real-time from anywhere in the world. But how can businesses make the most of this feature? This blog breaks down everything you need to know about WhatsApp voice calls, its benefits, key use cases and how to access the new WhatsApp Business Calling API.

## What Is a WhatsApp Voice Call?

WhatsApp voice call is a feature that allows customers and businesses to make high-quality audio calls over WhatsApp, eliminating traditional phone call charges. Unlike regular phone calls, WhatsApp voice calls rely on an internet connection, offering flexibility, cost efficiency and more.

WhatsApp Calling delivers voice over the internet like [traditional VoIP,](https://respond.io/blog/voip-crm-integration) but it works directly inside WhatsApp where conversations already happen. There is no complex setup, no switching between tools and no cost for inbound calls.

## Everything You Need to Know About WhatsApp Voice Calls

In this section, we’ll detail everything you need to know about making calls on both the Business App and API.

### On the WhatsApp Business App

Making calls using the WhatsApp Business App is straightforward. You can call any number in your contact list without any costs. All you need is an internet connection and you’re good to go.

For businesses using the WhatsApp Business App to communicate with customers, making a voice call is easy. All you have to do is click on the call icon at the top right corner of the chat inbox to call customers and customers can do the same on their WhatsApp App. There are no restrictions or limitations involved, unlike the API.

### On WhatsApp Business API

Businesses can have access to this feature only through a few selected WhatsApp Business Solution Providers like respond.io. 

To make calls using the WhatsApp API, there are 3 main things you should know: The type of calls, the availability of WhatsApp business calling API in your region and how calls are charged. Let’s dive into each of them.

#### WhatsApp Business Calling API: Types of Calls

The WhatsApp business calling API supports two types of calls:

* **Outbound Calls (Business-Initiated)**: Calls initiated by the business, which require user permission beforehand.
* **Inbound Calls (User-Initiate**d): Calls initiated by the customers to a business.

Now, let’s look at how these calls work.

##### **How WhatsApp Voice Calls Work: Business-Initiated Calls**

To initiate a call, businesses must send a permission request during an active Marketing, Utility, Authentication, Service or Free Entry Point conversation.

![This image shows how WhatsApp business calling's business-initiated calls work](https://assets2-proxy.respond.io/ph8r57dk1q9w/1FexeX41wTJtAGWrVS9ccy/791ca11080993b160352e7f55717d757/WhatsApp_Calling_Announcement_-_Image_1.png?fm=jpg&q=80&w=640) 
* A business can send up to one permission request within 24 hours and two permission requests over seven days.
* These limits reset once a call between the business and the customer is successfully connected.
* After the contact grants permission, the business must make the call within 72 hours.

##### **How WhatsApp Voice Calls Work: User-Initiated Calls**

![This image shows how WhatsApp business calling's user-initiated calls work](https://assets2-proxy.respond.io/ph8r57dk1q9w/14rTb5zZd0KHXZI7kmOzqR/742e3573d17b9ff6416a86823018733c/WhatsApp_Calling_Announcement_-_Image_2.png?fm=jpg&q=80&w=640) 

User-initiated calls are straightforward. Customers can start a call by clicking the call button in their WhatsApp app, through deep links embedded on business websites, apps or QR codes or via [interactive messages](https://respond.io/blog/whatsapp-interactive-message) with a click-to-call action. Businesses can choose to accept or decline these calls.

#### Who can use WhatsApp Business Calling API?

Starting from July 15, WhatsApp Business Calling API is globally available. Businesses already using WhatsApp messaging with at least one verified sender/number can now enhance their communication capabilities by adding voice calls. 

To leverage this feature effectively, businesses should have clear inbound and outbound calling use cases, such as:

* Resolving customer service escalations
* Conducting complex sales or marketing calls
* Utility calls for last-mile communication, such as customers calling delivery drivers to confirm or adjust orders.

#### WhatsApp Business Calling API Pricing

Calls via the API are charged based on various factors. Here’s a breakdown:

* **Call Type**: The charges vary based on the type of call, business-initiated or user-initiated. **User-initiated calls are free**, whereas business-initiated calls aren't.
* **Region**: Costs vary depending on the country code of the customer calling or being called.
* **Usage-Based Rates**: Rates are time-based and calculated per second.

Next, let's explore how you can use WhatsApp voice calls.

## WhatsApp Voice Call Use Cases

WhatsApp voice calls can be used in various scenarios to enhance business operations and customer interactions. Below are some of the key ways businesses can use WhatsApp calls effectively.

![This image shows the use cases of WhatsApp voice calls](https://assets2-proxy.respond.io/ph8r57dk1q9w/4339U96y0Y1VW076Q24yzj/9b01b4064713ff743e607ff5ba4ebe21/WhatsApp_Voice_Call_-_Image_2.png?fm=jpg&q=80&w=640) 

### Lead Generation and Nurturing

WhatsApp voice calls enable businesses to connect with potential customers when their interest is at its peak. When a prospect reaches out or shows curiosity about a product or service, a quick call can help businesses capture their attention, clarify questions and establish trust. This immediate engagement ensures leads don't lose interest or move on to competitors.

If a lead needs more time to decide, businesses can schedule follow-up calls to provide additional guidance, build trust and nurture the relationship through the sales funnel. As a result, businesses can enhance lead confidence and increase the likelihood of conversion.

### Sales and Consultations

For businesses offering products or services that require personalized consultations, WhatsApp voice calls enable seamless one-on-one engagement. Sales teams can provide tailored product recommendations, address specific customer needs and resolve objections in real time.

This immediacy accelerates the decision-making process, allowing leads to move confidently toward conversion. At the same time, businesses can foster trust and rapport, creating stronger relationships and driving higher success rates in closing deals.

### After-Sales Service

Enhancing customer loyalty goes beyond the point of sale. With WhatsApp voice calls, businesses can offer seamless after-sales support, such as troubleshooting, maintenance scheduling or feedback collection. This level of service strengthens customer relationships and encourages repeat business and positive word-of-mouth referrals.

### How can I activate voice calling?

### Can I record and transcribe my teams’ or agents’ phone calls?

Yes, simply use a call system that includes recording and transcription features for desktop and mobile apps.
