The Digitone Call Blocker Plus comes from the factory preset to allow all callers with a valid phone number displayed to ring through just like normal. Block unwanted calls are Unknown, Unavailable, Out of Area, Anonymous, Private or any name without a phone number and will be hung up on. Also, the phones throughout your home or office will continue to ring on Invited calls until the ninth ring, when the call blocker will answer the call and hang up to prevent a caller from tying up the line.
