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!
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.Read more ›
