In the mid to late 90s, phreaks spent a lot of time on teleconferences (known as "confs,") created a lot of mischief, and more than a few went to jail. Fast forward a decade and phreaks still spend a lot of time on confs, create even more mischief, and still occasionally go to jail.

More importantly, learn how new technologies such as VoIP can impact the trustworthiness of the telephone system (even including critical infrastructure such as 911).
