Sentry 2.0 Phone Call Blocker

My mother was averaging 25 to 30 telemarketers and solicitors phone calls a day. She’s on the state and federal Do Not Call lists, but they still called. This works perfectly. Blocks the calls so the phone isn’t ringing all day. We only add family and close friends to the white list. It gives us peace of mind knowing someone’s not trying to scam her. Very easy to set up. Well worth the money.

Works perfectly for me. Little weird to understand but has gotten rid of 100% of the annoying callers.

I installed this call blocker around 2 weeks ago, and so far it has blocked 100% of the spam / scam calls. I cannot understand why this product isn't rated 5 stars. Blocking 100% of scam calls deserves 5 stars. My thought is there are other reviewers who do not understand how this technology works and how to deploy it properly.I received a spam call from an unsolicited mortgage company at 5:40 AM a couple weeks ago. This was my motivation to find a way to block nuisance calls. While researching call blockers, I found some required you to actively add bad callers to a block list, while others use a community driven block list. The issue with a block list approach is that the scam callers are spoofing phone numbers and are always changing them.This device works differently. It auto answers the phone with a terse message that if you are a telemarketer, you need to remove this number from your calling list. If you aren't a telemarketer, you are instructed to hit "1" to ring through. This totally breaks predictive dialers because they are automatically dialing numbers and connecting them to a person when someone picks up. Whenever your phone rings three times and you pick up and no one answers, this is a predictive dialer trying to hang up before an answering service can answer. The predictive dialing technology does not have the intelligence to hit "1" so the call never rings through to the house. The agent who gets connected gets connected after the message has already played, so they don't know to hit "1".For known callers you can add them to a white list, which will allow them to ring through to your house on the first ring.I am using the device with the "free" version of Ooma. I have my Ooma telos device mounted in my garage next to my phone patch panel. This call blocking device is installed between the phone out line of the Ooma Telos and the wiring that runs to all my house phones. With this setup, you never hear one ring from the bad guys.Looking in my Ooma call log it seems that the incoming scam call volume is starting to drop off. Connecting agents to a what sounds like a dead line wastes their time and is probably getting my number dropped from their predictive calling list.

I don't use the white list,just reject the calls that go thru,which are @11 up to today,and these # never showed up again. works perfectly well. love it.
