An intermediate talk about phreaking today. Discussion will include information about INWARDS operators and how to reach them, along with Automatic Call Distributor phone exchanges that allow anonymous access to all sorts of weird locations (911 operators, local operators, etc.) while confusing the crap out of the people on the other line as they see you coming in from nonexistent locations. Also touched upon will be the basics of SS7, the IAM, differences between CID, CPN, and ANI plus CLIR and CLIRO. Discussion will include Caller ID spoofing, tips on how to increase your chances of getting a fully legal tour of your local CO, and other topics such as calling supervision, telephone extenders, and weird telco tie lines.
