Often we should call a person from one place, for example, from home, at a time when we have to be in another place - at work or school, for example.Of course, you can cheat, but if our backs do not have the characteristic sounds of the place we're talking about, it can give us. Have a set of sounds for all occasion, which is convenient to play on any device.
