Netheads vs. bellheads redux: the strange victory of SIP over the telephone
How much do you know about how the PSTN (that is, the public telephone network) works? At some point long long ago, it was signalled using in-band frequencies, which facilitated the infamous phreaking using so-called “blue boxes”.
