Place it right after the Discord Call Sound Button at the start of a clip, as the opening greeting before dialogue begins. Follow it with a short reaction sound for the other person's reply, keeping it as the first voice heard in the scene.
Über diesen Sound
The clip is a single voice stretching the Arabic phone greeting 'aloo' into one long, drawn-out hello lasting about seven seconds. There is no music or other effect, just that extended call for attention getting longer and longer. It feels playful and impatient, like someone waiting for a reply, which makes the drawn-out greeting itself the joke.
