Place it at the point a phone call breaks into a scene, then follow it with the Tuturu chime for a second anime-style alert before the conversation resumes. For a bigger reaction, put an Anime Ahh sound after the call is ignored, so the missed phone becomes the setup for the surprise.

This 1.5-second spoken clip has a character calling out Kyon's name to warn him that his phone is ringing. The delivery is warm, direct and a little teasing, with the name landing first and the phone following straight after. It feels funny and lightly dramatic, like an ordinary interruption given sudden importance, and it comes from The Melancholy of Haruhi Suzumiya.
