If you do not mind having a free non-open source Microsoft product on your Linux computer, the latest Skype for Linux release catches up to the Windows and Mac versions, providing most of the features they’ve had for some time. Microsoft rolled out Skype version 18.104.22.168 in mid June. The catch-up release has an updated user interface, some additional features, and lots of bug fixes. The latest Skype for Linux version also got rid of Alsa audio API support. Instead, it supports only Pulse Audio.
