Skype is a proprietary voice over Internet application that allows you to call other Skype users or real telephone lines. If you happen to use Skype for business or some other important calls that you might want to record, you will need additional software.

There are several ways to record inbound and outbound audio in Linux, but Skype Call Recorder (SCR) is specifically designed for Skype. It is a free and open-source application with which you can record calls in MP3, Ogg Vorbis, or WAV format. It supports manual and automatic recording, which can be configured for specific callers.
