Sonnerie is the French word for ringtone, and this clip circulates online simply as a short hi ringtone rather than as a quote from a known film, show or song. Its appeal online is its brevity and clarity, so it gets shared on soundboards as a ready to use alert and reaction sound. People reuse it for phone notifications, edit intros and quick greetings in short videos, where a familiar ringing hello is more useful than a longer musical ringtone or a spoken line.
