I remember seeing someone chost about sending back some special dial tones from their phone when they were receiving spam calls (i think those were calls from Ikea?), and completely obliterating the automatic call machine configuration with those frequencies.
That seems to me like the retribution deserved to some numbers that have been spam calling me recently, so i would like to do that.
But i don't remember who posted it, and i haven't been able to find that chost again. So if you have read that too and can point me to it, or generally know how can i achieve that, please share the info with me!
Thanks in advance!
