Speaking by voice from a PC, mobile phone or directly from a browser has become so normal like sending a WhatsApp message, whether for online gaming, work meetings, or simply chatting with friends and family. Skype's definitive closure in 2025 has made it clear that the sector has moved towards more modern solutions, with better audio quality, greater security, and many more features.
The problem is that there is now such an avalanche of voice, video, and messaging platforms It's hard to decide which one to choose: from classic apps like WhatsApp or Discord to ultra-secure options like Signal, Wire, or Element, and even enterprise VoIP tools designed for desktop use. In this article, we'll organize all these alternatives and explain what each one offers, what system it runs on, and what limitations they have for voice and video calls.
Best cross-platform voice and video calling apps
There is a group of "all-rounder" applications that work on Windows, mobile, and also via the webDesigned for both leisure and work, they typically combine chat, voice, video, file sharing, and screen sharing, and many have filled the void left by Skype.
Microsoft Teams
Teams is the direct successor to Skype within the Microsoft ecosystemIf you log in with the same account you used on Skype, your contacts, chats, and files are migrated automatically, so the change is almost transparent to the user.
In its free version, Microsoft Teams allows text chats, voice calls, and group video calls of up to 60 minutes.In addition to creating teams and communities, you can share your screen, change your background, record meetings (in paid environments), manage documents, and work seamlessly with Word, Excel, or PowerPoint. It's available on Windows, macOS, web, and mobile devices.
Zoom
Zoom became massively popular during the pandemic Thanks to its stability and good image and sound quality, it's currently marketed as Zoom Workplace, but the core functionality remains the same: cloud-based audio and video meetings with a highly optimized client.
In the free version, you can gather up to 100 people in the same video callWith a standard limit of 40 minutes for group meetings, although there are higher-tier plans that extend both the duration and the number of participants (300, 500 or more). It allows screen sharing with audio, displaying presentations, using virtual backgrounds, creating dynamic presentations, and using reactions.
In terms of security, Zoom has improved a lot.It offers optional end-to-end encryption for certain meetings, although enabling it disables features like transcripts and automatic recording. However, because it's under US jurisdiction, the platform is subject to the Cloud Act, a factor to consider in environments that handle highly sensitive data.
Google Meet
Google Meet has established itself as Google's central video calling service.It completely replaces Google Duo and unifies personal and professional use. It integrates with Gmail, Calendar, and Google Drive, making it much easier to organize meetings and access shared documents.
With a free personal account you can create meetings with up to 100 participants and a duration of 60 minutes.From your browser, mobile device, or desktop app, you can share your screen, blur your background, enable real-time captions, and schedule meetings from your calendar. Users without a Google account can also join via a link.
The connection is encrypted in transit, but it is not pure end-to-end encryption.Therefore, organizations that require the highest level of confidentiality may prefer other, more closed alternatives.

In the free version you can invite up to 4 participants per roomWith a 30-minute limit per meeting and only one active room, it includes chat, group video calls, screen sharing, and the ability to watch YouTube videos within the meeting.

The first stable version of the c-toxcore protocol was released in 2025.It is considered mature, although many user clients are still under community development and have not passed external audits. Clients like Toxygen (desktop) or Antox (Android) cover Windows, macOS, Linux, and mobile, but development is fragmented and not all are equally polished.
Some users report occasional disconnections, loss of messages in offline mode, or some instability in group video calls.Even so, for those who prioritize privacy and can tolerate some usability shortcomings, Tox is a very attractive option.
WhatsApp, Telegram, Messenger and other everyday apps with voice input
Beyond the "serious" video conferencing platforms, many people end up using the usual messaging apps to talk by voice.both on mobile and desktop. They're convenient because almost everyone has them installed.
WhatsApp is the queen of messaging, but also a very practical option for voice and video calls.In addition to text chat, it allows you to send voice notes, share files, use screen sharing, and create huge groups.
Group chats can accommodate up to 1024 members and group video calls support up to 32 participantsMore than enough for most everyday uses. It has apps for Android, iOS, Windows, and macOS, as well as WhatsApp Web in a browser.
The content is end-to-end encrypted, including messages, voice notes, and video calls.The main criticism comes from the metadata that is shared with Meta (contacts, connection information, etc.), something that does not affect the content but does affect profiling.
On desktop, WhatsApp Desktop mirrors your mobile conversations. It allows you to send messages, share files, and make one-on-one voice and video calls. Its main limitation is that group calls and video calls from the desktop are more restricted or simply unavailable on certain systems, and you need the associated mobile app.
Telegram
Telegram has established itself as a robust alternative to WhatsAppwith a strong emphasis on public channels, bots, and cloud storage. For voice and video calls, it offers a good balance of security, flexibility, and performance.
Voice and video calls are end-to-end encrypted when the appropriate modes are used.And there's also a secret chat mode, which encrypts text messages and allows you to set self-destruct timers. It's one of the few apps that lets you block access to the application itself, adding another layer of privacy.
Telegram Desktop is more minimalist than the mobile version, but it allows messaging, calls, and channel management.It syncs all conversations across devices and offers unlimited storage for shared files. It also supports group video calls and persistent conferences that users can freely join and leave.
Facebook Messenger and Instagram

Messenger allows group video calls and Rooms for up to 50 peopleUsers can join even without a Facebook account via a link. Chats sync across mobile, web, and desktop apps, and include stickers, GIFs, voice messages, and file sharing.
Instagram, for its part, offers smaller group video calls, for up to 8 people.focused on social use. For businesses, Messenger integrates with pages, chatbots, and widgets on websites, facilitating customer service and automated campaigns.
On the downside, privacy in the Meta ecosystem often raises concerns.End-to-end encryption in Messenger has been rolled out gradually and may not be available in all contexts, so it's best not to handle highly sensitive information through these platforms.
WeChat is the dominant messaging app in China It combines chat, social networking, mobile payments, and a host of other features. For voice and video, it allows individual and group calls on mobile, web, and desktop.
Group video calls are usually limited to about 15 participantsThe platform includes features such as discovering people nearby, mini-programs, integrated commerce, and much more. For businesses operating in the Chinese market, it's practically indispensable.
Its desktop version replicates the WhatsApp model: it synchronizes chats and allows basic communicationHowever, it doesn't offer all the advanced features of the mobile app, and chat history isn't automatically replicated between devices unless the settings are adjusted.
Discord
Discord was born focused on gamers, but today it is a true hub for communities and teams, widely used for leisure as well as for projects, online classes or remote work.
Its strength lies in persistent voice channels, where you can freely enter and exit. While you play, work, or share your screen. Servers allow you to organize multiple channels and user roles, with different levels of permissions.
Direct group video calls support up to about 25 peopleVoice channels, on the other hand, can group more users simultaneously, combining voice, camera, and screen streaming at different qualities (including HD in Nitro plans).
It is available for Windows, macOS, Linux, iOS, Android, and web browsersoffering a fairly consistent experience. In return, the interface can be somewhat chaotic for those unfamiliar with it, and some advanced features are geared more towards video games than businesses.
Slack and team communication tools on Windows

Slack
Slack structures communication into workspaces and thematic channelswith instant messaging, threads, reactions, and a powerful system of integrations with productivity tools.
In terms of voice and video, Slack allows direct calls and small team video calls.as well as screen sharing. However, the quality is usually lower than that of specialized solutions like Zoom or Discord, and many advanced features are reserved for paid plans.
The desktop version for Windows and macOS is powerful but somewhat confusing.In many cases, the app redirects to the web version, and the experience isn't always as seamless as with simpler tools. However, its integration with services like Google Drive, Salesforce, Dropbox, and Monday makes it a powerful command center for teams.
