Viber Business Calls: Complete Guide for Businesses
Published: Feb 3, 2026

Viber is a messaging application with over 1 billion users across the globe.
It has a significant user base across Eastern Europe, the Middle East, and Southeast Asia.
Rakuten Viber launched a new feature called Viber Business Calls in January 2024.
The feature enables businesses to communicate better with their customers.
This guide covers everything you need to know about Viber Business Calls and how Viber can help your business communicate better with your customers.
What Are Viber Business Calls?
Viber Business Calls enables Viber users to call businesses directly through the Viber app.
The calls are free for users but incur a per-minute cost for businesses.
This service aligns with Viber’s vision of becoming a super app that includes a range of services like messaging, chatbots, advertisements, and voice calls.
The key points are as follows:
- Free calls: Viber users will not incur any charges, anywhere in the world, including international calls.
- Business-funded calls: Businesses will incur a flat rate per minute.
- In-app calls: Viber Business Calls will allow users to make calls within the Viber app.
- Special business numbers: Businesses will have a Viber voice number with 3-10 digits instead of a regular phone number.
How Viber Business Calls Work
Understanding the Viber Business Calls mechanism will allow businesses to determine if it is the right medium for their support services.
From the Customer’s Point of View
There are various ways for the customer to initiate the call to the business.
Some of the ways are as follows:
- Business Profile
- Within the Chat
- Call Links
- Business Directory
All of these are initiated within the Viber app.
Customers are able to see the business’s profile, including the business’s name and logo, before the call is initiated.
This call is initiated directly to the call center of the business.
From the Business’s Point of View
There are four steps for businesses to set up the Viber Business Call.
They are as follows:
- Add the Business Call button to the business’s profile within the Viber Business Account.
- Choose a Viber Number, or use the call center’s existing phone number.
- Connect the VoIP solution with the Viber setup.
- Customers are able to call the call center from anywhere, without the need for the call to be made within the Viber app, nor will the call cost the customer any additional money.

Viber Business Calls vs. Viber Business Messages
Knowing when to use voice or messaging will help you plan a good multi-touch communication strategy.

When to use voice: For complicated problems that require explanation, for sensitive problems where a personal touch is required, for urgent problems where quick help is required, and for sales pitches where building rapport is necessary.
When to use messaging: For simple queries, for sharing documents or images, for communicating across time zones, and for conveying information that can be referenced later.
The best way to use both voice and messaging is to give the customer a choice between both and to allow them to easily switch between both.
