no, you'll need to acquire an aux ringer. radio shack handles those, your looking for a 90v ac ringer. you can get those from your provider, by simply calling and paying to much, but they do carry ringers that can break glass at 40 yards, designed for outdoors at a construction site type area.. (i put one under my bosses desk once, he never asked me to turn his vol up again)
