Call Control Home syncs to our global database via your smartphone. Bad actors are added to our list based on over a million reports a month from all over the globe. Similar to junk email, while we can’t guarantee we will block every spam call, our cloud-based algorithms quickly identify the worst offenders, dramatically reducing harassing and dangerous calls. Subscribers can also add any number instantly to their personal block list by pressing the button on top of the Home unit or via the smartphone App.
