Its not a feature, its just a byproduct of the way the system works. Some phones actively mute it or otherwise cancel until you actually answer but for all useful purposes a circuit is a circuit is a circuit...When you call someone that ringing through is an open connection the same as a two-party speaking conversation. Of course youll see some variations when you start talking about one brand of phone calling another from one network to another etc etc but most of the Sprint phones I've had over the years did this if conditions were right.
