    Phone calls - scam 3rd Nov 16 at 10:20 AM
    We keep on getting scam calls from 00490273481563 - supposedly from TalkTalk re our internet service - the caller is an indian woman and it is starting to get annoying !
    3 already this morning alone ...
    I have reported the number to TalkTalk but can they block foreign calls ?
    What is the best way forward ?

    Just had second scam phone call in two days from Asian male purporting to be from Talktalk.

    He said our internet connection was showing problems on their servers and asked me to log onto my computer. Told him we didn't have a computer and he hung up

    My latest one is to tell them that I only deal with scams that are put in writing rather than over the phone and ask them to write to me. I just repeat this a couple of times and then they hang up. Boiler room share buying scam is the latest one I am getting, someone has got hold of the list of Woolworths shareholders (I had a few dividend shares I never did anything with) and they are offering to buy your worthless shares. You just need to provide a few details ....

    Make a recording on your smart phone of one of these and play it when they ring:

    Just bought a BT phone with Call Guardian to replace an old phone that was getting iffy.
    Had it about a month now. No calls from call centres have actually made the phone ring, although we have had a couple most days according to the log.
    So far only one problem with a "wanted" call getting through. That was down to the person calling though.
    So I reckon that's the best "fix" for the unwanted calls.

    0345 163 2127 is a number that is not in service. However, calls never actually come from non-geographic numbers. Calls can only come from a landline or mobile phone or from a VoIP user. When you see a non-geographic number on screen, this is merely a "presentation number" programmed by the caller.

    When a call is received from a genuine outbound callcentre, caller display will not show the number of the calling line, it will instead show the central number for their inbound call centre should you wish to return the call. It is however, not permitted to show a premium rate number (070, 084, 087, 09, etc) on caller display.

    When a scammer calls, the caller display could show almost anything. They also have equipment that overrides what is shown on screen. The caller display screen could show a premium rate number that makes them money if you call back (this is how "missed call" scams, aka "wangiri", work), a number that doesn't exist (so you can't call back or trace call), a number that belongs to someone else (such as a bank, to try to "prove" the scammer is really your bank) or just random junk (so the call cannot be traced by the called party). It will not show the caller's actual number as that would make them easier to trace.

    Caller display in no way verifies who is actually calling. It may give a hint as to who is calling but only if you recognise the number.

    No.

    Additionally, any call blocking based solely on caller ID is doomed to failure. Scammers have learned to change the presentation number each time they call.

    The only solution that works is for all unknown callers to be issued with a verbal challenge which has to be passed before the called phone rings. This is the approach adopted by the plug-in trueCall devices and this is the system that is built in to the BT Call Guardian handsets.

    Yes it is.... but not on the PSTN (Public Network). With an ISDN connection you can see not simply the 'presentation' number, but the actual line I'd used to make the call. This is viewed by looking at the C7 signalling field and once known you can do all sorts of clever things, even with ISDN2. You get to see withheld and spoofed numbers (along with the code that says do not show!). However, costs for such flexibility do not come cheap and with a normal phone line all you can realistically do is block or ignore.

    Why don't they offer the alternative of Opt in - rather than Opt out ?
    When ALL of your calls are blocked - unless you accept them ?
    This would allow us peace and quiet - with only those that have prior permission getting through ....

    Unfortunately, such a system would be unworkable and the telephone system would become unusable.

    You would have to create and maintain a list of everyone who might call and who you would want to hear from... and how could you possibly know who all of those people are in advance?

    If any of your contacts changed their number, they would be blocked and would have to find some other way of letting you know their new number.

    If I've got a few minutes to spare, I just keep saying 'speak up - I can't hear you'. By the time they cotton on to the fact that I'm winding them up, they're (hopefully!) too hoarse to bother anyone else for a bit. Otherwise, just say 'no' and hang up.
