I'd like to get my hands on the SOBs running the ones for Obama. I'm
tired of having the damn things wake me up. It would be a case of
justified homicide.

I'm mulling over a design for a box that blanks the first ring, reads
the CID... no match to addressbook = continues to blank ring and lets
it roll into VM (legitimate caller, cold caller won't wait that long).

800, 877, etc... short line to "answer" call with dead air ;-)

I'll need help from a person experienced with uP's. I can manage the
analog.

Hi Jim,

Do you want a PC app or and embedded app ?

I ask because, how would you get the "addressbook" information into an embedded app.

A PC app has the entire PC for "database" storage.

Of course, "blanking" the line for all extensions maybe a problem.

Not a problem at all... insert box at telco entry point into house.

But the display portion needs to be available to the user. ( you )

It must be a stand-alone especially for decent sales.
Most people will not tolerate a computer in his kitchen where the phone outlet is (space, looks, etc).
It would be nice, but not too cost effective and/or feasable to use the attached phone's keypad, so...one seems to be stuck with having a keypad on the black box.

Why not pass info back-and-forth via USB to a PC, location of your
choice, or even use a wireless router??

...Jim Thompson
This is the crux of the question.

Is this a PC app with all the resources available to a PC or
Is this a standalone app with limited resources.

I, as many here have developed CID devices in the past.
Not much analog involved, CID chips abound, add a microcontroller and software and its done.

I purchased a caller ID box from Target or somewhere a few years ago, disassembled it and found on 8051 single chip processor inside.

Removed the chip and replaced it with my own.

Was kind of fun for awhile, but it never got finished.

That is where my questions are coming from.
