Telegram Desktop uses this short tone to confirm that a voice call has ended, making it one of the app's most recognisable interface sounds for desktop users. As Telegram grew into a widely used messaging platform, the tone began appearing in screen recordings, reaction videos and meme edits, where it instantly signals a real call rather than a staged one. It remains popular because it is short, neutral and easy to recognise, so creators can use it to close a scene cleanly without distracting from the joke or dialogue that came before it.
