I want to know more about the feature before I get excited about it. Does it only silence calls that show up on the caller ID as 'Unknown'? If so, that feature has very little benefit to me. Probably only 1 to 2 percent of the junk calls I receive actually show up as 'Unknown' on the caller ID. The rest of the junk calls I receive have spoofed the caller ID so that the area code and exchange is the same as my number but the last four digits are different every time. THOSE are the calls I really want to silence.
I also get calls from people who intentionally block their numbers. So unless this feature sends all blocked numbers, unknown numbers, etc. to voicemail then it doesn't have any real value to me.
