Place this clip after the call connects, as the voicemail reply, and follow it with a shocked reaction once the caller realises they were fooled. For a longer prank, add a laugh after the reaction to close the joke.
O tym dźwięku
This is a Russian answering machine message lasting about seventeen seconds, presented as a recorded voicemail greeting rather than a live voice. Its recorded tone makes a listener pause and wonder whether anyone is really there. That brief uncertainty feels awkward and funny, especially when it arrives in the middle of a call, and it works best when the listener does not expect a machine to pick up.
