You know, whenever I try that, they always hang up before it gets
nearly that far. Has Tom Mabe ever done the foreign servant answering?
That's one of my favorite ones, and with caller ID, you can almost
always tell when you can do it before you even answer. :-)))))))

On a similar note: Anyone familiar enough with modern telephone

Note that I said "ringer", I want the phone electronics, in particular

Do you need two answering machines ?

Years ago when I purchased my first 9600 baud modem, the modem also had
voice/CID capability.

The software that came with the modem had an answering feature based on
the incoming CID.

A different message could be played with each CID.

If the CID was welcome, the phone connected to the pass thru port would
ring.

Google for awhile, I am sure its still out there.

The only modems I have need to be connected to a PC to work - and I don't
fancy the electricity bill for leaving a 200W PSU running 24/7!

Also the modems I have were all S/hand and don't have the full featured
utils disks with them - only the bare minimum drivers I found online.

What's needed is a simple automated switch box, if CID is detected it routes
the call to my regular answerphone with a polite OGM, if no CID is detected
then it routes the call to a second answephone with an offensive OGM.

Preferably based on an Arizona microchip PIC as I have a programmer for that
family.

Connect the ringers to a spare wire, and let your interface turn on
all the ringers by connecting them to the proper side of the phone line.

This house isn't as nice as the old one out north in the desert...
there I had a telephone bundle the size of my thumb running throughout
the house :-)

But I do have a spare pair... I dumped the fax line and switched to an
Internet fax arrangement... 1/6th the cost.

And the V-Tech (portable) phones seem already to have this feature,
they seem to wake-up, read CID, then ring.

I need to get rid of ab out 35 fax machines. I'll probably just
attack them with the cordless screwdriver and a hammer. People ask for
them, but want full ink or toner cartridiges and a case of paper when
you offer them for free.

Sometimes newer isn't better. It was easy to modify old WE or S-C
phones for all kinds of options.

Since your V-Tech already has that part covered, all you need is to
read the CID, and disconnect them from the line while your custom
hardware either disconnects the line, or sends it to an answering
machine. A marketable product would either allow you to select which
way you want to connect the phone, or have to jacks to allow the use of
both types of phones at the same time. A lookup table would make quick
work of identifying blocked numbers, and flash memory is cheap, these
days. The hardware could either be stand alone, or run in the
background on a PC that runs 24/7.

I would take on the design if my shop was usable, but it's going to
cost over $10,000 to replace the 1600 square foot roof and finish the
other repairs. The other problem would be that I can't get caller ID on
my Lifeline phone service.

Why bother when you can get BT to answer with a message saying "This number does not accept
calls from unidentified callers, please redial enabling your caller identification", if no
CID is present.

I'm on Virginmedia not BT, they charge £2/month for anonymouse caller reject
and it only stops legitimate callers - not the nuisance telemarketer.

For someone with a bit of experience programming the PIC, a simple no CID
diverter box could probably be done with a 12F PIC - just enough pins for
supply rails, input and 2 relay control lines.

The nuisance telemarketer is somewhat adept at cheating the anon' caller
reject, I think they send a CID during ringing but when I do a 1471 the
recorded message tells me the service has cleared, the solution would be a
16F PIC that records the last, say 5 CIDs and displays them on a 44780. A
16F627/8 would probably be more than equal to the task.

Any volunteers?

As I mentioned in another post, the original scheme I thought of probably
won't work.

The one particularly persistent telemarketer was able to defeat the
anonymous caller reject VM were charging me an extra £2 a month for,
presumably they were sending CID between the rings so they got through. But
when I dialled 1471 to get their number I got a recorded message that the
service has cleared.

A PIC 16F627 that does nothing more than decode and store the last 5 CIDs
and allow me to scroll through them on a 44780 style LCD would enable me to
report the nuisance telemarketer to the telephone preference service.

If all you want is to record CID numbers, an off the shelf CID could be
had very cheap.

Also, sometime ago here in the US, someone sued a telemarketer and used
their CID box to prove that there were an excessive number of calls.

A CID box that can not to be tampered with was admitted as evidence.

Ring voltage is required to "arm" CID acquisition.

You are trying to make it too complicated.

Disable the ringers and connect ALL of them to a spare conductor in
the four conductor station wire. (Yellow or Black wires.) Then connect
it to the line when you want the phones to ring. Process the CID. If
you want the phones to ring for that call, close a set of relay contacts
to activate the ringers. If the call is to be ignored, use another
relay to to put a 600 ohm resistor across the line for a few seconds to
answer, then drop the call. A third relay could redirect the call to
your answering machine.

If you need them, there are external ringers that can be used to let
you know a valid call is waiting.

I just did a search for caller ID decoder chip and also found none
available.

Looks like this technology is just too 1990.

I know I have a few chips from projects I did in the 1990s, but they
won't help you in the UK.

Looking at surplus houses will be the only recourse.

With a bit more searching, I found a page with the 16F628A CLID box
including firmware files:

http://www.picbasic.nl/frameload_uk....rmelder_uk.htm

The listings are given as pages - not *.HEX & *.BAS files, I've done select
all copy/paste into freshly created *.TXT files - is it sufficient to rename
the extensions appropriately?

That just leaves me with the problem of where I can get an 8870 DTMF

I must have missed something.

The 8870 is a DTMF only device, don't you want CID ??

Is CID that much different in the UK the the US ??

Here is a data sheet of the 8870:
http://www.futurlec.com/Datasheet/Zarlink/MT8870DE.pdf

According to this site:
http://www.ainslie.org.uk/callerid/cli_faq.htm


"British Telecom developed their own standard, which wakes up the
display with a line reversal, then sends the data as CCITT V23 modem
tones in a format similar to MDMF. "

Is this standard DTMF ??

If I remember correctly, you are in the UK.

Google has over 2M hits for "caller ID box".

On the first page, the hits are all in the US.

"caller ID nox UK" has 260K hits.

This is the first one:

With a bit more searching, I found a page with the 16F628A CLID box
including firmware files:

http://www.picbasic.nl/frameload_uk....rmelder_uk.htm

The listings are given as pages - not *.HEX & *.BAS files, I've done
select
all copy/paste into freshly created *.TXT files - is it sufficient to
rename
the extensions appropriately?

That just leaves me with the problem of where I can get an 8870 DTMF
receiver (or equivalent).
Futurlec lists it for cheap.
How much is minimum order and shipping from US to UK?
I must have missed something.

The 8870 is a DTMF only device, don't you want CID ??

Is CID that much different in the UK the the US ??

The schematic I found has an 8870 between the phone line and the
16F628A - It came up on a google search for: "microchip PIC + caller
ID"., maybe I need to double check the accompanying text.
I think I have found the confusion from he
