Function is_call_with 

pub fn is_call_with(words: &CallWords, title: &str, text: &str) -> bool

is_call with these words: a missed call can wait, video or voice (“Missed video call”, “Appel vidéo manqué”); one ringing cannot. Each word is matched whole (words::holds_word), as docs/words.md says: “vous appelle” rings, never inside “vous appellerez”.
