Skype launched in 2003 and became the default app for internet calls and messaging on Windows through the 2000s and 2010s, especially after Microsoft acquired it in 2011. Its voicemail feature used short system tones to signal a recorded message when a contact was unavailable. As editing culture moved to newer apps, sounds like the discord call tone and the familiar Discord notification took over, but the Skype voicemail chime remains shared on soundboards as a nostalgic marker of that earlier era of desktop messaging and missed online calls.
