Product Description

This article analyses Caller-ID, a form of calling number identification (CNI), which is similar to automatic number identification (ANI), in light of its privacy and social equity impact, and presents research findings that tend to support the precedence of callees' rights to know who is using their time and equipment over callers' rights to anonymity.

People who said this does not block all calls did not try and figure it out.. Must be on first line in the home before any other phones.. If you put an answering machine in line first, then you have the PERFECT screener.. I programmed in all the numbers that were important for me into list A,,, Others that I did not want calling too late or too early into list B. I set up the unit to accept A list calls 24 hours a day, B list calls from 10am to 10pm and NO other calls. If someone calls who is not on A or B list it goes to the answering machine and the phones never ring (of course solicitors seldom leave messages)!!! If someone calls that I did not program in, the worse that happens is it goes to the answering machine and I can add them to either list A or B so the phone rings next time (all calls show up on caller ID of unit)... Set up this way the unit screens EVERY call and blocks all unwanted calls... Unit works best when in "sleep" mode,, goes into sleep mode after 30 seconds of inactivity or when you power off then on. VERY happy with this product,,, worth the money and time to set up for peace of mind.. I now get NO calls that I do not want.... No need to try and individually block every possible call by adding to a block list.. Much easier to enter the calls you DO want to receive then EVERY OTHER CALL, NO MATTER WHERE IT IS FROM, IS BLOCKED AND PASSED ON TO YOUR ANSWERING MACHINE.. My only regret is that I did not find out about this device sooner,,, If you prefer and have just a few numbers you want to block, you can program 20 numbers in list R (including 000-000-0000 which blocks all "unknown callers)... Seems easier to me to just list the ones I want and exclude all other numbrs...

Finally! The phones have stopped ringing! But now, when they do ring, I know it is a call I want to answer.

I must say I am very pleased with this product and its "white list" concept. I agree with one reviewer that the unit could use more memory and would indeed be easier to set up using a computer interface. In fact, put me on the short list to buy the next model of this device after a USB port and programming software are added!

Yet even as the product is, A and B lists are relatively easy to set up. (As currently configured the R list of blocked numbers is not useful, in my opinion, because it is limited to only 20 numbers.) I have my phone system set up in layers: first the phone company's Privacy Manager screens unidentified calls. If caller ID is blocked, the caller is given the opportunity to get through by being voice screened. I put the Privacy Manager number on my B list, set to ring only between 8 a.m. and 6 p.m. Other numbers on my B list are the doctors, dentists, hairdressers, and other businesses -- all "9 to 5" type callers. My A list is set up with only the numbers of friends and family members. I have the A list set to ring at any hour, though that can always be changed if necessary. If I'm not at home, all of the A and B "white list" calls that don't get answered within 5 rings go to the answering machine.

What about all those calls with Caller ID that are not on the "white list"? The answering machine picks them up. If a friend changes their phone number and doesn't tell you, their call does not ring the phone, but it still goes to the answering machine after they hear five rings and they can then leave a message. Same thing with all those other calls that have Caller IDs like "877 services" or whatever. Any person who has a caller ID can leave a message if it is important.

In short, a flexible solution that gets the job done!

After the Federal Do Not Call list proved to be a complete joke I need a way to block calls. I was getting as many as 10 calls a day from telemarketers - and worse, collections people that were looking for people I have never heard of. These collection people were out of control - some calling 10+ times a day even though I explained I never heard of the person (and this could easily be verified by looking up my number in the phone book...). So I spent the $80 to buy this. (Note: Some sellers on Amazon are selling this for as much as $125 - but I spoke to the guy that actually makes them and there are ZERO differences - so don't waste the extra $50). You essentially have the ability to create 3 lists, an A, B and R. You can create a schedule and do things like the A list can always get through, the B list only certain times and the R list never. Each list can hold 70 numbers and despite what another reviewer said, you can in fact use wildcards so you can, for example, block 1-800-xxx-xxxx. I am on AT&T U-Verse VOIP, so I can confirm it works on VOIP systems. I do in fact get peace and quiet now - call never rings and goes to my online voice mail system. I did a good bit of research before buying this. The only "perfect" system requires a dedicated computer/modem. This was the best stand alone. That said, it has many faults:

1) The directions suck. Little things like they explain programming a number using the area code and number - and after an hour of programming I discovered that does not work. You must use a 1 then area code and number (at least on my phone service).
2) The unit does not pass through caller-ID. So if your phone has caller-ID on it (and what phone doesn't these days?) it will not show anything.
