    Is that likely in the UK..?

    But how can I detect it if it is being done (even if it is illegal)?

    There are plenty of illegal taps. This is a web page which describes
    former police officers actually doing it.

    "The company charged clients between £5,000 and £7,000
    to hack into computers and £6,000 to bug telephone lines.

    The MPS was initially contacted by British Telecom, who
    had identified a number of devices attached to junction
    boxes, which they suspected were being used to intercept
    phone conversations."

    As far as I am concerned it is by then, too late. The info has been

    What you post makes a lot of sense but incoming callers may be disuaded
    from ringing a mobile on account of the costs.

    Similarly, long outgoing calls will be probitively expensive for me from
    a mobile.

    I'm not familiar with VOIP but could I use VOIP and set up an encrypted
    link between me and the VOIP provider? Access to a VOIP server seems to
    me much harder than access to a manhole cover in the street.

    I do not disbelieve you.

    In part, it's a question of probabilities. For most people the
    probability (as far as they know it) of getting tapped is close to zero.
    They might find this discussion sounds bizarre and paranoid.

    In my case, the likelihood of this happening has moved from almost zero
    to maybe, let me guess, 30 percent. That is way too high for my

    But how does anyone function effectively these days without using a

    Sorry to be so dumb but this all seems quite complicated to someone
    like me who has never used VOIP.

    Presumably such a setup still allows mew to keep my existing phone

    Is there perhaps an easier way to do this without having to work with
    the technology at the sort of level you are writing for?

    Possibly because they have already been sold. Try auctions, instead. I
    have been totally shocked by the stuff that is sold at Government
    Surplus Auctions. Not to mention what I have found in auctioned-off
    filing cabinets, that clearly have not been emptied, or checked, prior
    to disposal.

    No, I am not even going to mention what kinds of stuff are disposed of.
    Use your imagination, or better, go to a few.

    Read what I wrote, perhaps?

    "...visually inspect whatever bits of your telephone line might be
    accessible to you."

    If they are lawfully tapping your phone, you will never detect it. If
    they are unlawfully tapping it - then the first place to do is to
    visually inspect any of your phone line wiring that is accessible, but
    not in the outside patch box. Any addition to the latter is more likely
    to be spotted. There is quite possibly a junction box in the building,
    down in the basement, perhaps. Or in a shared hallway. I'd look there..

    Ah, ours is way ahead of yours, we buy non working junk in the first
    place to save the effort of having to try and repair it later. It's much
    more efficient that way.

    The UK military went through a huge downsizing and "contracting out" a
    while ago. They closed all sorts of "interesting" research places and
    large amounts of kit appeared in auctions, afterwards. Most of it
    working, much of it even in date for test. Many lots were mis-described
    or described as "units, various".

    Sigh. Such days are rare. Here.

    : : Doesn't your government waste money by junking

    No, they prefer to leave laptops containing everybody's personal details
    in unattended cars in Birmingham.

    What you write sounds as if it would normally work but sadly in this
    case it is not going to be if use.

    I have already seen how the other side leaks absolutely nothing.

    They observe and they learn and, when the time comes up, they use what
    they know. But they never say what they know. No bluffs, feigns,
    intimidations or any of that.

    It can be quite scary to observe them in action when it is then clear
    just how much they knew all along but by then they have made their move.

    No, I didn't. Benj just isn't very good at snipping posts to keep the
    necessary attribution in place.. I wrote none of the following:
