Here in rapidly degenerating S.Africa where the judicial system has become non functional, and majority controlling shareholders are looting my inheritance by extracting all value for themselves by way of [self appointed - legally] director's fees, I need some technology leaverage. Obviously in a non-functioning society, you must DIY.
The looter's actions indicate that they are tapping into my phone line which goes through their PABX.
In the telco-room I've located my pair and their pair on the tag-blocks.
How would I best hear their speech ? Since I've got easy regular access to the tag-blocks, and I seldom receive calls, I could set-up occasionally for a few hours at a time. Ie. not use a long-term set-up.
My first thought is to just temporarily connect my pair to theirs, observing the polarity, and while leaving mine on-hook, just tap-off my line into an amplifier, which I can hear while I'm working.
A second refinement, would be to use capacitive coupling to their pair.
I need to terminate my side with a high impedance, so that the capacitive coupling can also have a high impedance. So that it becomes insignificant when I receive or make a call.
If I remove my handset, so that only the audio amplifier terminates my line, during 'listening in', would it work ?
And then by just connecting my handset and/or modem could I expect to operate without significant cross-talk to the looters line ?
Thanks for any info/feedback,
