Fantastic device was getting 45 nuisance calls every weekday nothing to lose so bought this device easy peesie to set up at 1st a couple of calls got through 02872129997 02883184560 02387737874 and 01379384562 but just hit the big red block now button have not heard from those numbers again only had my call blocker in for a few weeks so far but so far so good i am not convinced such a device will block 100 of nuisance calls but this cpr call blocker shield come pretty dam close

The instruction manual could have been a tad clearer

Essentially this particular model bars all calls you the end user simply inputs the numbers you wish to allow through

You need to ensure your telecom supplier has calling line id cli enabled or else the device won’t work

Negative points that’s not the fault of the device as mentioned this device initially bars all numbers and you have to enter the telephone numbers you want to allow

While this is the most effective way of stopping unwanted calls it also means that if you call for example the garage and ask them to call you back you need to ensure your device allows that number

Some people don’t allow their number to appear on your phone and can sometimes appear as ‘number unknown’ or ‘out of area’ the device won’t allow that call to progress

It does exactly what it says on the tin i get great pleasure of getting a scam call allowing them to talk to me for five minutes then pressing the big red button to abruptly cut them off and blocked them forever
