The above listed open source solutions are great but they do require some setup. Not everyone you wish to call might be using the above software, so here are some free ones you can use.
- Hangouts is one of my favorites when it comes to quickly making a video call. It allows for up to 10 people on a group call which is more than sufficient for me in most cases. Also, hangouts has chat messaging and support for screen sharing.
- Viber is another app that allows video, audio, and text-based chat for its users. It is available on most platforms and has a strong user base.
- Discord has mostly been associated with gaming. However, it offers a great way to chat with multiple groups and people. Discord has support for video calls and screen sharing as well. But its voice chat is something that has received maximum appreciation.
