The Skype for Linux client used its own variant of the classic Skype calling sounds, with a simpler, more electronic outgoing ring than other versions. While Skype dominated online voice calls in the 2000s and early 2010s, these interface sounds became widely recognized shorthand for internet calling. Even after Skype declined in favor of Discord and other apps, creators kept ripping and reuploading its tones for nostalgia and parody. The Linux outgoing call version remains popular in edits that want an authentic, slightly off-kilter tech feel.
