I used to call my buddies pagers(beepers) then punch in other peoples numbers, the cops, if they did a cash job, the irs. One guys girlfriend was so pissed, I paged him to all kinds of different numbers all the time, she thought he was banging someone else, I did it to a superintendent that I worked with, his phone and others with that company got cloned, they had to shut them down for awhile. That was a lot of fun.
