One caveat to all this is for business users, and that's because working with any video streaming service can be tricky over a corporate network. While basic setup is enough to get one session running, be sure to work with your IT staffers to test what happens when multiple streams are open. You're looking for artifacts or excessive buffering that disrupts the stream which can happen if the video stresses the bandwidth limits of your network or your Internet connection. Also, if you have remote users that connect to the Internet using a virtual private network (VPN), be aware that these services often also cause bandwidth problems that can affect video streaming performance.
Signal Private Messenger is one of the most popular privacy chat apps. It features end-to-end encryption for all messages, voice calls, and video chats between two Signal users. It focuses a lot on individual chats. There are group chat features, but it's mostly for personal use. This is one of the biggest differences between it and rival privacy chat app Telegram. Video calls worked fine in our testing so we have no trouble recommending them. It's a neat way to get some encrypted chats as well. The app is also completely free and open source. You can't really go wrong with it, but there are better video chat apps if you need group video chats.
