When is police called?

Hi, I got the annual plan for ring. There has been a few times my alarm went off by accident (forgetting to turn off the alarm before coming in, wrong setting to away instead of home, etc). For all the times the alarm went off no cops showed up or I did not get a call. We did turn it off with our phones or imputing code into the keypad. When are the cops called to come to the house or does it deactivate once the code is put in or someone turns it off from their phone? Without any follow up how would ring know it wasn’t a break-in and someone just stole ones phone to turn it off, because who ever owns a ring system know how it works. Thanks
