Place it where a conversation breaks, between the last spoken line and the reaction shot, so the scene shifts without extra dialogue. Open with the Discord Call Sound to establish the ringing phone, then let this clip close the exchange, and finish with the Vine Boom Sound Effect when the other character realises what just happened.

This three-second clip carries the clean digital tone of a Samsung phone call starting and then ending, the brief signal listeners instantly recognise from everyday mobile use. It feels ordinary and slightly awkward, like a conversation cut off before it really begins, which makes it quietly funny in the right context. The sound comes from Samsung's standard call audio.
