I am sick to death of getting nuisance calls (despite being signed up to the Telephone Preference Service..), most lately from five digit spoof numbers from Delhi, pretending to want Darren Norbury (who?) 'but while you're on..'.
Plusnet can't help, and so I just gone and got me one of these call blockers.
Here's the gen..
CPR Call Blocker V.103/104 refurbished
The ALL-IN-ONE Call Blocker filters all calls made to your home and checks the calls against its UNIQUE built in ‘Rogue Calling numbers list’ supplied by the Call Prevention Registry
Built In Number List
The CPR Call Blocker is pre-programmed with more that 200 numbers which are 'deemed' as known nuisance callers. Companies which are selling by phone,using overseas call centers and automated sales lists are all pre-programmed which will minimize the sales calls you receive almost immediately.
Block Now Function
The ‘Block Now’ button is located on the top of the unit. At the touch of a button the unwanted caller’s number is logged into the unit’s memory, the call will hang up and the number blocked permanently. Use this feature to block unwanted callers as they are calling you.
Withheld UK Number Blocker
This will reject any caller who withholds their number.
Overseas Number Blocker
This will reject any overseas callers
Unavailable Number Blocker
This will reject any unavailable callers
VOIP Call Centers Blocker
This will reject any VOIP Style Internet Nuisance Callers
Last Calling Number Blocker
This will block the last visible number from your call log
Area Code Blocker
This will block the Area Code of a calling number or the first 4 or 5 digits of any number
(This function helps to combat the new style PPI calls that use 1000s of different variations of one number, 08757 652 7757 – 08757 652 7758 )
I hope this is useful to someone. I'm still naffed off I have to pay to stop these parasitic organisations from pestering us, but if I'm going to pay I'd rather bag a bargain :) The going rate seems to be around £37 ish (Amazon - £45+ on Maplin) and so even though it's a refurb it seems reasonable.
