Most Helpful Customer Reviews
This review is for “Series Installation” which is recommended by the seller to try first. This worked for me so the other “Parallel Installation” was not necessary.
First, it cost only $39.00 as of the date of this review so stop all the complaints about features not included. The seller HQ Telecom has this item available on their website for the same price with shipping included (aka free). I purchased thru Amazon because I have Prime. The description on the seller’s website says the blocker is version 5, the latest. The description on Amazon as of the date of this review does not state a version. I contacted the seller who said the blocker sold thru Amazon is also version 5.
Once the blocker is setup the day to day is operation is fairly simple. To block phone numbers, unblock, check numbers while you were away, etc. requires just using a button or two. This is intuitive after just a couple of uses.
Just blocking the "not available", "unknown" and the area codes 855, 866, and 877 made a huge difference in the number of calls that come through. I work at home and having fewer calls has been wonderful.
Nice Call Blocker. Easy to install and understand. The only downside that it only prevents the phone from ringing, it does not block the incoming call from showing up on your Caller ID screen. This shows that it is not a true Call Blocker that truly blocks calls. I had to order this service from my phone company in order to truly block a survey company from calling me every day.
