Prompt used
Emergency call sequence: a caller dials 112 and the call reaches a call-taker. The dispatch system fetches the caller's location from the mobile network. The call-taker records the incident type (road accident) and priority. The system suggests the nearest free ambulance and police vehicle; the dispatcher assigns them and the job appears on their terminals. The caller gets an SMS with vehicle number and expected arrival. Units update status on the way and at the scene.
