Is there a way to block unknown and telemarketer calls? I already have anonymous call blocking on, which does great at blocking "Anonymous", but 99% of the telemarketers and solicitors display "Unknown" on the caller ID. I want to block this as well. I heard there was a way to require all callers to push 1 * to get through. This effectively blocks out telemarketers and solicitors that are using computer dialers to contact you. Is there a way to turn this on?
I am already on the "Do Not Call List", but local organizations still call for donations. I've been on the do not call list for over a year also.
