WhatsApp Voice Call: All You Need to Know in 2025

WhatsApp has been the messaging app of choice for numerous people globally for years. It has grown to be an everyday platform that people use to share information through secure, easy, and intuitive means.

Although its text messaging capabilities made it popular and there was a voice call facility on WhatsApp, it was not available in the WhatsApp Business Platform. So, you would have to use an external WhatsApp API provider that supports voice calling functionality. 

But by adding voice call functionality to its Business Platform, WhatsApp is enabling you to connect with customers in an ultra-personalized fashion. And with WhatsApp being an online application, it can let you shift away from regular calls towards a VoIP alternative.

Optimized for real-time engagement, WhatsApp Business voice calls can be an excellent means by which you can offer customer and sales support to maximize your communication. That being said, in this blog post, I will discuss what the WhatsApp Business voice call option is and if you should consider using it to drive your business forward.

What is WhatsApp Business voice calling?

WhatsApp voice call is a beta service that leverages the messaging system on WhatsApp to enable brands to make voice calls using an internet connection rather than the cellular network. It employs VoIP (Voice over Internet Protocol) technology to send your voice through data either on your mobile data or through Wi-Fi.

Originally launched in 2015 for personal use, this feature has evolved significantly. So much so, that in 2024, WhatsApp released it in a private beta by partnering up with various WhatsApp Service Providers to enable businesses to utilize it to make real-time communication from an interface familiar to everyone.

What are the benefits of using WhatsApp voice calls?

WhatsApp voice calls provide an enterprise-grade communication channel that competes with standalone calling and meeting apps with the familiar WhatsApp UI. Whether you're reaching out to a customer for support, arranging a demo, or jumping on an impromptu sales call, these improved capabilities enable you to provide a stable and easy-to-use experience.

No need for extra tools

The greatest benefit to using WhatsApp voice calls is that it is within an existing framework that your customers are already utilizing and comfortable with. It is beneficial to you as well in that you don't need to buy external tools to make VoIP calls to customers.

Seamless support & conversions

Using both WhatsApp messages and voice calls helps your customer-facing reps to better engage with your customers. For example, if a customer is having an issue understanding a certain feature or product capability, a support agent can send a video explaining the said feature and connect via a voice call to provide a more personalized walkthrough. 

This aspect of voice calls allows you to promptly close support tickets or handle common sales objections to convert leads quickly. 

Simplified conversations 

If you own a business, chances are you know about WhatsApp marketing or are probably using it to connect with your target audience already. You can operate all your WhatsApp interactions from one single platform by integrating WhatsApp voice calls into your company. Also, most WhatsApp tools offer a centralized inbox that enables you to handle chats from one place with complete ease.

A safe channel of communication

Carrying the same standard of security as WhatsApp messages, WhatsApp voice calls are secured with end-to-end encryption to protect sensitive data from external threats. WhatsApp follows strict safety protocols so you and your customers can chat without worrying about WhatsApp or other sources listening in on your conversations.

How to use WhatsApp Business voice calls for your business?

To incorporate WhatsApp voice calls into your marketing and support environment, you need to access the WhatsApp Business Calling API. Using this API your customers can simply tap the call option in the WhatsApp App or by clicking on the button in the message they received. 

The business-initiated calling is available in India, Mexico, and Brazil but you will need to get customer consent. To acquire this contest, you can send a call request through WhatsApp when a currently used promotional, authentication, utility, or service request is open. 

You can send 1 call request in 24 hours and 2 requests within a week. Once a user accepts your request, you can call them once within 74 hours after receiving consent. These guidelines are subject to change in the future. 

You can take advantage of the WhatsApp Business Calling API to connect with international customers cost-efficiently and without any delays. Plus, the call UI shows your customers your business name and the Green Tick verification mark to tell them they are talking to a legitimate business. 

The Calling API uses the internet to connect calls. This feature is similar to other video or voice calling software like Viber or Skype. Since you are conversing over the Internet, you don’t have to worry about the duration of the call or the per-minute cost. If you are on a Wi-Fi connection, your network carriers will not charge you for the WhatsApp calls.
