    Hey yall!
    I know this is prohibited and unethical!
    But when I was small one of my uncle's friend made a circuit which can receive signals of telephone conversation of a fixed phone (PSTN) to a mobile phone (GSM). I remember ones he let us use that machine. It was connected to a PC desktop speaker. Was not much interested those days but now when I wanted to try it since I'm studying telecommunications, I couldn't find any info about such a cct.
    One of my friends told me that I need a GSM module for this! But he doesn't have any idea what we're to do with the module :/
    So any expert could please help me on this?


    Regards!

    Are you sure it was GSM and not just cordless?

    Hello,

    Tapping phone conversations is illegal.
