Timer Class loop

programming flash
1

I’m trying to create a loop of a phone that rings every 5 seconds using the Timer Class.
The problem I have is when it gets to function stopRing and noRingTimer.start(); it goes backs to function onTimerComplete not the start.


package {
    import flash.display.*;
    import flash.events.*;
    import flash.events.TimerEvent;
    import flash.utils.Timer;




    public class Phone extends MovieClip {
        var noRingTimer:Timer = new Timer(1000, 5);
        var ringTimer:Timer = new Timer(400, 8);

        public function Phone() {

            mPhoneScreen.visible = false;
            noRingTimer.addEventListener(TimerEvent.TIMER_COMPLETE, onTimerComplete);
            ringTimer.addEventListener(TimerEvent.TIMER, ring);
            ringTimer.addEventListener(TimerEvent.TIMER_COMPLETE, stopRing);

            noRingTimer.start();


        }
        
        public function onTimerComplete(evt:TimerEvent):void {
            trace("Start ring!");

            ringTimer.start();

        }
        public function ring(evt:TimerEvent):void {
            mPhoneScreen.visible = !mPhoneScreen.visible;
            trace( "ring " + evt.target.currentCount)
        }
        public function stopRing(evt:TimerEvent):void {
            
            noRingTimer.start();
            trace("stop ring")
        }

    }
}
