Place it at the point where a character realises the call has failed, then follow it with the Classic Error Sound Button for a second failed attempt, and open the scene with the Discord Call Sound Button so the sequence stays part of one connected call.

This clip is a 13.5-second phone-style error message delivered in Cantonese, Mandarin and English, with each language taking its turn to say the call cannot go through. The switch between languages makes it feel awkward, confusing and unexpectedly funny, like being passed between three different operators. It works best as a short, puzzling interruption rather than a straightforward announcement.
