This setting allows users to blacklist a phone number. Once a number has been blacklisted, all calls from that number will be automatically rejected (phones will not ring when the blacklisted number dials through). Users can also configure a response to be played to the blacklisted caller. Optional responses include immediate disconnect, continued ringing with no answer, or a customized message.
Say you’re being inundated with calls from a merchant services company asking for your business (that never happens, right?). By accessing your system settings you can blacklist the number, ensuring the next time they attempt to call the phone won’t even ring. You’re in control.
