Phone phreaking:

Phone phreaking is a technique in which phone phreaks spend their time dialling around the telephone and trying to learn the pattern of tones to know how the calls were routed, how to imitate operators and other company personnel, trying to know the concealed telephone company technical journals, digging into the telephone company trash bins so as to know the confidential documents. This lead to the invention of electronic devices like blue boxes, red boxes and black boxes which helped the hackers to access the network and make free phone calls. Thus it started gaining popularity as a type of computer hacking.
