Essential Info

Do unwanted phone calls distract you? Are the telemarketers, non-profits, bill collectors and wrong numbers driving you crazy? Do junk faxes waste your time and money? Does the phone ring every time you try to get some sleep? Then BLOCK them using the Caller ID with Ring Controller - you won't ever have to deal with these nuisances again.

This easy-to-use device lets you determine which calls always get through, which calls can only come in during certain hours of the day, and which calls can go straight to your answering machine. When a call comes in, the phone ringing is suspended for a second while the incoming number is sent to the microprocessor. The microprocessor checks the caller's relationship from your preset phone number lists to determine whether to allow your phone to ring or not. Then, depending on who is calling and what time of day it is, the phone will ring or remain silent based on your wishes. The result: No more annoying interruptions! You don't have to know which calls are unwanted, you only need to know who you want to talk to and the machine will handle the rest!

This product is also available in black.

Note 1: This product does not work in the Toronto, Canada area.
Note 2: Caller ID Service - To use this device you must sign up for caller ID service from your local phone company. Most telephone companies offer two levels of caller ID service. The basic level is only to display the phone number. In order to best utilize the full potential of this device, you need to be subscriber for the full service (Phone number and name) provided by your local phone company.

    I have used this device for over 9 months and am entirely satisfied with it. What I really like about it is the ability to use wildcards to prevent whole phone prefixes e.g. 800, 900, 832, etc. This proves very effective. In addition you can eliminate unknown callers as well by sending them all to the C list. YOU MUST HOWEVER READ THE INSTRUCTIONS. PS - one LIMITATION is that the incoming number will only appear on the device and not forward to other connected wireless phones. However if you have programmed the device correctly this will soon not be an issue.

    I have a new phone number.I get countless calls from collection agencies looking for someone that used to have this number. This machine worked for me.

    This gadget DOESN'T FORWARD THE CALLER ID to your phone, making it completely useless for cordless phones! The only thing the phone displays is "Incoming Call"--you have to look at the gadget to see the caller ID, and if you're phone isn't right next to the gadget, you can't do that. So unless you keep your one-and-only land-line phone right next to the gadget, forget it. If you have a cordless you carry around, or more than one cordless handset, forget it.

    If works fine on the phone it is connected to. However if you have more than l phone the other phones will still ring. So to eliminate this we have turned off the ringers to the other phones.Wish there was some way that it could control at least 2 phones. Other wise it was worth spending the money and I would recommend this to anyone trying to eliminate all unwanted phone calls.

    Does exactly as described. A bit difficult at first to use, but you get the hang of it quickly.
    CAROLE L -- san francisco, CA   4/5/2010
    Excellent product, reasonably priced. Lightning fast delivery from company. Happy with purchase.
    RONALD -- phoenix, AZ   2/18/2010
    Unfortunately this Product has flaws that aren't pointed out in their advertising. First, even though a call is accepted, the display name and number of this call will not come up on your caller ID, which means that the person calling may be someone that you want to talk to, but you will not be sure who it is. For me this was a show stopper. The disclaimer that this would happen was on page 13 or so of their manual. This product should have been designed to allow all numbers through initially, and then we could screen in or out the numbers that are acceptable. This product looks to be a lot better than it really is. When I pointed out the discrepancy to the Manufacturer, they told me that I could return the product since other customers had complained about this problem too.

    This is the first device that has the full capability to block all those unwanted calls. Have had it a few weeks and it works exactly as advertised. Freedeom from unwanted calls at last. I highly recommend it.

    After using Ver.1 last year with some work around for the 11 digit long distance numbers, I purchased the Ver.2 It is the greatest unit that solved the problems with the longer phone numbers. Added bonus is the 70 numbers "R" register. A few days after I received it it had an intermittent power problem, so I purchased another one for a replacement unit . Smarthome shipped one immediately. However before I received the second unit, I spotted the cause of the trouble with the first one that was simple to correct. I called Smarthome that I will not return the defective unit because I repaired it and I want to keep both. Now I have two Ver.2 units on two phone lines. I am very satisfied with both working exactly the way I need it with my setup. I still have the Ver. 1 as a spare third though.

    When I purchased your older 5107w Ver.1 last year, I had to change my Phone Provider to make it work in Toronto area. I also had to do some workaround to use it with the eleven or thirteen digit long distance numbers. But the box worked great. Now I purchased your new 51071 Ver.2 box and I couldn't be happier. No more workaround needed with any long distance numbers and as a bonus the Reject List is now up to 70. I give it 5+ stars as it does everything I want.
