I am the OP. Just to clarify ....
There are several ready-built gadgets available on the high street
here in the UK to record a phone conversation. They cost little and
provide an audio feed from a jack plug which can go straight into a
basic voice-activated recorder. Simple. Cheap.
So if I actually wanted to record a phone line I would use something
like that. Perfectly legal too.
However I have asked about something different. I want to switch an
electrical device on when the landline is in use. My question is how
to attach to the landline. Something non-invasive is better and I
suggested a magnetic switch. If it has to be a plug-in device then
that's ok although it limits the location of the point of attachment
to only where the sockets are.
It is often illegal to attach things to a telephone line but then that
is also often ignored.
The indicator circuits should be easily adapted to drive a relay instead
of a light.
The tricky (for a beginner) part is to detect the drop in line voltage
when the line goes OFF Hook.
You sit in the dark waiting for phone calls?
I suspect there are already purpose-built devices that can do the same.
I haven't alleged that you are pursuing any particular application for this,
though it may be related to your quest to capture callers numbers as per
your other thread.
Are you referring to the post by "Lemmo?" in which case how would I know
that Lemmo == Jim?
Otherwise, this is the only reply by "Jim" that I've seen.
I'm actually not interested in the law (though I've always understood that
all parties should be aware that a recording is being made, unless you
belong to the security forces).
Well, you didn't identify yourself as the OP, nor have you said they are the
Well that was exactly my point. What is it that you are planning to do with
I haven't said you are trying to pursue some unsavoury application of the
technology, I have just expressed an opinion that such applications exist
and I wouldn't assist this quest for information without knowing the actual
Quite honestly I can't imagine any of my friends or associates having a need
for such a device and I would be concerned about them if they did ask me. I
have no doubt that there are legitimate and benevolent uses for such a
device, just as there are malevolent uses. It's the first time I've been
described as having a paranoid outlook, somewhat ironical perhaps given your
quest in another to log peoples phone numbers?
If I were a landlord, I might use such technology to spy on my tenants,
If I were an employee I might use such technology to spy on the company
If I were a jealous husband I might spy on my wife
Those are three applications I wouldn't wish to help anyone with. As for
others who have been helpful, I don't consider that a good role model
considering the possible repurcussions to others if this technology were
I still have little idea why you want this technology and again I personally
wouldn't help anyone construct such stuff without knowing more about the
application (which from your other post may be logging callers numbers)..
You can clearly state your intention, I just hope that people will consider
what they are helping someone to do. If you weren't so coy about this I
wouldn't have posted.
It may well be that given the exact application you had in mind people might
have been able to suggest a more targeted solution.
What is it you are trying to do?

You can record for your own private use, without giving notice. This is
equivalent to having an excellent memory or taking detailed private notes,
which also is not a crime.
Anything involving third parties is usually a matter of consent by both
people in conversation, or of officially warranted interception.
Consent can be tacit, in that if an employer records phone calls for
business purposes, they cannot be found guilty if an employee decides to
complain at the recording of a private call they decided to make out of
their employer's phone system, unless they can demonstrate that they had no
grounds to beleive a recording was being made.
This is based on what I know of UK law. Beyond that it gets too subtle for
No, but see the other thread by Jim.
There are plenty of legal things I don't think people should do and there
are plenty of illegal things people do regardless of the law.
You have the intended context wrong. I was thinking in terms of jury rigging
equipment - adapting/customising it if you wish, certainly not a use of the
word jury in a legal sense.
Well clearly I can't police people morality, neither do I or anyone else
have to aid people either.
The commercial availability of things has no bearing on their final

In the UK it is legal, if it is done on the user's side of the master
socket. Terminals are often provided for the user to do exactly this. There
are guidelines to follow though, and the phone company has the last word.
If they take issue with something, it must be removed or changed to a form
This seems far more likely than the bizarre things you suggest.

I have corrected your misunderstanding once already and given you a
link (above) to check up the details. It seems that a sneerer like
you prefer to carry on with the sneering and false innueundos than
read the facts.
Then do not feel you have to help. As I pointed out, you do not even
have to post if you havenothing of value to add to this thread.
Even the most innocuous thing can be misused. My bread knife can be
used to kill. Someone can drown in a bathful of water. An electric
bar fire can be used to burn someone. An electric drill can be used
to maim someone. A car tyre & petrol can be used to burn someone to
Despite these horros, we stillmanage to live with these appliances.
I don't get asked stupid questions when I buy a car tyre or run a
bath and it would be better if you didn't ask them either.
There are any number of things which one might want to switch on when
a phone call is being made. It's probably best if you stop being coy
and accustory through adopting that false facade of innocence. "I
only pointed out that it was possible that the OP could electrocute
the cat and also activate the microwave in which his puppy was placed
and then destroy the building by a timed fuse on some explosives and
do all this by remotely calling his phone line and having the call
trip his deadly switch". Get real.
I am setting something up to ensure safety for someone in the
household who is suffering trauma and I do not feel I need to go into
lots of snips..
Then I wish you luck with it, whatever it is. I can't help but feel that for
whatever your trying to accomplish there's a more direct route to the
solution, and no I don't want to know any more, I'm done with this.
So after saying that you, oooooh, couldn't possibly help unless you
were able to know more and more of situation (to the point of almost
prying into a third party's distress) you now say you have nothing to
So why waste everybody's time while you kept needling away at what is
obviously an uncomfortable situation for someone I know. And then
you declare that, "oh well if that's the case, it is too serious or
too delicate" for people like youself to be involved.
Are you some sort of master time waster? Or someone who tries to
Perhaps you didn't know anything helpful in the first place? Maybe
you just pretended to gave something to say and just wanted to take
on a very loud and overlbearing moral tone in the hope that people
like myself who have a genuine need to seek info will be intimidated
by your sniping?
Would it be asking too much to either contribute something as asked
in the original post or not to make any further remarks about how
innocent and correct you are.
I was really concerned about what was planned for this device since there
are many improper uses for such a device and it is very, very unusual to
need any kind of phone triggered device. I still struggle with this a bit.
Knowing that there are inappropriate uses to the technology I really don't
know why you're so angry that I've had a concern about the final
Throughout the thread you have been secretive about what you planned to do
with such a device. If this was a straightforward application you probably
would have told us all about it by now.
If this is related to your attempt to capture callers numbers, then I
suspect you may be dissappointed - it's easy to withold a number from
nuisance calls and you'd have to involve the authorities to capture the real
You've already had a load of suggestions from other posters.
I've raised my concerns, you've half explained why you are pursuing this -
it's time to move on.
If this is really required to aid a family member, concentrate on them and
consider if this route is really the best form of action.
What impropers uses could there be in all reality? Only someone who
wants to live on the margins of real-world probability would dream up
some weird use and think that to be the most likely.
Archiving CLID numbersis one thing and switching a device when the
line is in use is another.
So what on earth are you talking about?
If I wanted to capture callers' numbers I would use a CLID machine
but why would switching have anything to do with that?
And a lot of strange stuff from you.
In other words, you have nothing to offer.
Don't bother to make a display of your crocodile tears.
