A rushed caller who hangs up mid-ring — are they lost?

No: a four-second unanswered call is a missed call like any other, so the text goes out in under 10 seconds. And rushed people often answer by text what they didn't have time to say out loud — the text recovers what the ringing lost. If the caller answers neither the first message nor the single 4-to-6-hour follow-up, we stop there, no pestering. Their request, if there was one, stays in the dashboard with their number, for a manual callback on your side.
