## Overview

The Sentry 2.0 Phone Call Blocker is a cutting-edge device designed to eliminate spam calls automatically.

## Description

Do you hate it that even after installing a call blocker, you still get spam calls from unrecognized numbers? If you do, try SENTRY.SENTRY works like a real sentry guarding your house phone. It recognizes the friendly numbers (White List) and let them in, it recognizes spammers (Black List) and hangs up on them. For unrecognized callers, it will perform 'Stop and Check’ which will let in the ‘good’ callers and drive away the ‘bad’ callers. This unique Active Blocking will block 100% robo junk calls and 99.9% of telemarketer/solicitor calls. All you need to do is to set up a White List, that includes your friends and family members, doctor offices, pharmacies, etc. Once you have the White List set up, SENTRY is fully automatic. There is no need to hit REJECT button anymore. You will no longer be bothered by those annoying telemarketer calls, not even one. And you don't need to do a thing! There is no need to hit REJECT button like most other call blockers. Worried about missing important first time calls? SENTRY allows first time callers to press 0 and ring the unit so you can pick up the call. By pressing 0 the caller's number is automatically saved to the White List. If you are not ready for the Active Blocking, SENTRY can be used as a conventional call blocker with Black List. You can choose to have SENTRY to block based on Black List only. SENTRY has a Black List capacity of 1500.Please watch SENTRY intro video for more details.

## Questions & Answers

**Q: Is it possible to turn off the new "auto save to whitelist" advanced feature so it is a pure whitelist blocker?**
A: No way to turn off the "auto save to whitelist".  Unfortunately sometimes unwanted callers do press "0".  I had mine setup for 2 or 3 days when one of the computer support scammers dialed 0.

**Q: If a new caller presses zero will he be able to leave a message on my answering machine?**
A: Yes,surely,it can work.For since the new caller presses zero,their calls were added to white list forever.And at this time,if you don't pick up the message.Then caller can leave a message to your answering machine as normal.

**Q: Any products with - contacts go through, non contacts go to answering machine, blocked #'s get hung up on?**
A: I would also like such a new product. It could just trick the phone answering machine to answer with 10 fast rings or such. That would also say don't answer to me. I hope they create it soon, I have #1 and buying #2 and will buy your version when they make it.

**Q: Versions 1 and 2 look alike.  How does one tell the difference between these 2 units?   Is there a model number or version # printed on the units?**
A: The photo on Amazon for the Version 2 is actually showing a Version 1 which adds to the confusion. There are three identifiable differences between the models.  1) Version 2 does not have the Sentry symbol before the Sentry label on the device.  2) Instead of the language labels under the VOICE button, version 2 has A/B/C/OFF.  3) When turning over the device, version 2 has a battery compartment while version 1 does not.

### ⭐⭐⭐⭐⭐ 







  
  
    No more telemarketers.
  

*by D***  on Reviewed in the United States on 14 September 2024*

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.
