Technology is changing the way we communicate. Today, instant messaging is playing a crucial role, offering communication channels that are more effective than email and even replacing the need for traditional landline telephones.
As a result, there’s no shortage of instant messaging solutions for business. But what about internet phone call apps? Thanks to advances in VoIP technology, some instant messaging apps double as apps to make free internet calls.
One thing’s for sure: as business communication becomes increasingly global, security and reliability are top priorities when searching for the best calling app. In fact, 86% of consumers require security from their VoIP service provider, while 85% expect reliability.
Top 10 Best Apps for Making Online Phone Calls
Whether you’re using a PC or an app for your phone calls, calling another dedicated user, or even a landline phone, these are the best online phone call apps.
1. Chatox
Chatox is one of the best apps for free internet phone calls. Is that because it’s powered by Brosix? Of course! But that’s not all. How many other apps for calling offer you unlimited-size file transfers, a native whiteboard solution, and screen-sharing? Go ahead, we’ll wait.
With Chatox, you’ll get high-quality voice and video chat on a free-to-use and user-friendly platform. You also get real-time text chat, group chat rooms, and the rich feature stack we alluded to a bit ago. Better yet, all communications on Chatox, including calls, take place over fully encrypted, peer-to-peer channels.
It makes Chatox a great online calling app and a highly secure solution rich in features and collaboration tools. Check it out!
“Chatox is lesser-known but stands out for its ease of use and modern interface. It simplifies team communication with features designed for quick interactions and collaborations. One major advantage of Chatox is its lightweight and fast performance, even on lower-end devices, which can be a game-changer for global teams with diverse hardware.” — Connor Butterworth, CEO and Owner, Southwestern Rugs Depot

Pros and cons
| Chatox Pros | Chatox Cons |
| Free internet phone calls | Comparatively limited customization |
| High-quality voice and video chat | Occasionally, calls freeze due to connectivity issues. |
| Fully encrypted, peer-to-peer communication channels |
Available on: Windows, macOS, Android, iOS, Linux
2. WhatsApp
WhatsApp is without a doubt one of the most popular internet phone tools.
To get started, you just need to confirm your mobile phone number. WhatsApp then syncs your contacts, so you can see which of your friends are using the app. Once synced, you can call your WhatsApp friends straight from the app, wherever they’re located, using your internet connection instead of your phone plan’s limited voice minutes.
With WhatsApp, you also get the ability to send instant messages, chat in groups, and share your location, videos, photos, and other media. You can also make video calls. There are desktop and mobile versions, but both you and your call recipient need the app to make calls.
Keep in mind that WhatsApp messages backed up on Google Drive aren’t encrypted, and WhatsApp has exhibited major vulnerabilities to malicious spyware. And while you can’t call landlines, with 2 billion monthly active users, WhatsApp’s online calling potential is unrivaled.
“One big perk of WhatsApp is its multimedia sharing. We can quickly send photos, videos, documents, and even voice messages, making our chats lively and effective. Plus, the app’s user-friendly interface is a lifesaver. Even the least tech-savvy on our team got the hang of it fast, which means everyone’s on board without much fuss.” — Laia Quintana, Head of Marketing and Sales, TeamUp

3. Viber
Viber is an increasingly popular platform for making online calls. The free mobile calling app offers desktop and mobile versions and supports seamless calls and communication between the two.
Once synced with your mobile phone number, Viber combs your contacts to find other Viber users. Developed by a former member of Israeli intelligence, Viber offers end-to-end encryption on all calls, texts, and group chats, as well as photos and files sent on the app.
For a fee, Viber Out lets you subscribe to Viber for a local number in various countries that you can use to call non-Viber users and receive calls and texts.
“Viber is known for its strong encryption and free international calls. It provides solid security for sensitive chats. One downside is its lower user base, which might limit its effectiveness for larger teams.” — Cesar Cobo, COO, Webris
Viber pricing: Free; With Viber Out, you can make unlimited calls to 57 countries for €5.99 and try it for a week for free.
Pros and cons
| Viber Pros | Viber Cons |
| Cross-platform availability | Inconsistent call and video quality |
| Easy setup and sign-up process | Limited market reach in certain regions |
| Supports individual and group chats | Group chat is limited to 250 participants. |
| End-to-end encryption for secure communication | Cluttered interface, according to some users |

4. Telegram
Telegram is another internet phone app that’s growing in recognition. Telegram allows you to call other Telegram users for free, as well as send text messages one-on-one and in groups.
Telegram is available in desktop, mobile, and web versions. You can share unlimited photos, videos, and files. Telegram features are available anywhere you log in, and you can even make internet calls through the web. Cloud-based infrastructure lets you sync messages between multiple devices.
Telegram has risen in popularity for a few reasons. For starters, its client-side code is free and open-source. Telegram also offers encryption, but keep in mind that it doesn’t encrypt chats by default. Secret chats and voice calls are encrypted end-to-end, but the former has to be manually turned on. That could lead users to a false sense of security.
If Telegram isn’t for you, the other apps on this list should suit you fine. Or try one of these capable Telegram alternatives.
“For global team communication, Telegram excels because it allows asynchronous and synchronous communication effectively. The app’s notifications and pinned messages help keep everyone on track despite time zone differences. With voice calls that have decent quality and reliability, Telegram integrates well into daily operational workflows.“ — Casey Meraz, CEO, Juris Digital
Telegram pricing: Free; Depending on where you live, Telegram Premium, which includes Telegram Business, varies in price.
Pros and cons
| Telegram Pros | Telegram Cons |
| Unlimited cloud storage for messages | No default end-to-end encryption |
| Supports large group chats | Phone number binding exposes contacts |
| Allows you to send large files up to 2 GB |
Available on: Windows, Windows Phone, macOS, Android, iOS, Linux, Web

5. Vonage
Vonage is one of the best VoIP apps to make online calls. With Vonage, you get reduced rates for international landline phones and mobiles.
Once you sign up you’ll get a Vonage box, which you’ll connect to your router and phone. You’ll then get voicemail, 911, call waiting and forwarding, and even access to weather and traffic information. For a fee, you can add another line or a fax, for instance.
The mobile app syncs your existing contact list, and Vonage users will appear in a dedicated section of the app.
“In my experience, Vonage excels in call quality and affordability. The sound is always crystal clear, and the connection is stable even when calling internationally. I’ve had instances where I had to conduct virtual training sessions with clients in different countries, and Vonage never failed me. The rates are also very competitive, which is a big plus for us since we make a lot of international calls.” — Benedict Ang, Senior Fitness Coach, Total Shape
Vonage pricing: Free trial with $10 in credits for new users; Basic at $13.99 per month; Premium at $20.99 per month; Advanced at $27.99 per month (all prices apply to an annual subscription).

6. Messenger
Facebook began life as a social network to connect students on university campuses in the U.S. Not only has it become the most popular social media platform, but you can also use its Messenger app to make free online calls.
To make a call on Facebook Messenger, both users need the Messenger app. Messenger automatically syncs with your Facebook friends, so it’s easier if you and the other party are friends there. Or you can search for users through the search feature.
Messenger doesn’t support phone calls to landlines, but you can make free internet phone and video calls desktop to desktop, desktop to app (and vice versa), and app to app. Messenger works from any web browser.
Just consider the risks of free instant messengers for team communication. Try a workplace messenger instead. Many workplace messengers, like Brosix, provide the ability to make calls.

There is also an instant message option when you’re on a call. It is a part of Google Workspace, a suite of productivity and collaboration tools by Google.

FAQ
What is Wi-Fi calling?
Wi-Fi calling is a feature that allows users to make phone calls over a Wi-Fi network instead of using a cellular network. It is especially useful when you are in an area with poor cellular coverage but have access to a strong Wi-Fi network. Wi-Fi calling is also a great option for international calls, as it eliminates the need for expensive roaming charges.
What are VoIP calls?
Voice over Internet Protocol (VoIP) calls are phone calls made over the internet instead of using traditional phone lines. Various devices, such as computers, smartphones, and dedicated VoIP phones, can make internet calls, which often cost less than traditional phone calls. They also offer additional features, such as video calling and screen sharing, that are not available on traditional phone lines.
Can I make international calls for free using online calling apps?
Yes. Some apps offer free calling to other app users who have the same app installed, regardless of their location. Other apps allow you to make calls to both landlines and mobile phones in other countries at a fraction of the cost of traditional phone services.
