Any one have any experience with dtmf (beeps and boops over phone) but using rj45 instead of rj11?
I viewed a claim that the intel me can produce dtmf instructions that will be regarded as noise by tools like wireshark and can be used to transfer things like encryption keys surreptitiously over the net without being seen by monitoring tools.
Essentially data is hidden in sight as noise on the line and picked up somewhere else.
Rj11 phone line can do this. But can it be done with rj45? Wouldn’t the first switch it hit just smooth noise?
