Microsoft Teams is Microsoft's workplace chat and video meeting platform, and its call ended tone is the short notification users hear when a call or meeting disconnects. As remote and hybrid work became part of everyday office life, the sound became instantly recognisable to millions of workers, even outside formal meetings. Creators began lifting it into short videos and memes to mark an abrupt ending, a rejected idea, or a conversation that goes nowhere. Its familiarity and brevity keep it useful as a quick, wordless punchline for work and online life.
