Abstract 

Phreaking in the age of Voice Over IP? What the hell is Voice Over IP? If you're asking this

question and you're interested in phones and thought phreaking was dead back in the early 

'80s when blueboxing died, or 2002 when AT&T killed redboxing on long distance calls 

then this is the speech for you. Or if you know what VoIP is but want to know how the hell 

it has any impact on phreaking you should also attend. This talk intends to educate it's 

audience on the new age phreakers. Most of the discussion will involve a detailed 

explanation of Calling Party Number(CPN), ANI, and Caller ID, and the differences between all three, 

we will also be covering the basics of phreaking with Voice Over IP technology, Asterisk, and VXML. 



Not all of this presentation will be dealing with VoIP, this is a basic new age phreaking 

presentation that will show the latest techniques that phreaks are using today -- it's not 

just about free calls either, hell you get that with VoIP anyways! You will learn not only 

why VoIP is important, but such things as Spoofing Caller ID(and no we don't mean 

orangeboxing, Social Engineering Telus, our methods are simple to use and will cost as little as $15/month)  



As technology is rapidly changing, so is our phone system. We will be discussing a basic 

over view of Voice Over IP and some of the services provided by many of these so-called 

"Broadband phone companies." We will also be discussing Calling Cards that use VOIP 

technology to provide cheaper rates to their customers. We intend to explain how VoIP is 

changing the phone system and making it very easy for the every day consumer to spoof 

Caller ID by spoofing Calling Party Number(CPN), and how this can be exploited to circumvent 

security in such things as Voicemail, Credit Card Activations, and even Telephone company 

numbers that when you call from your "own phone" will give you complete control over your

dial-tone telephone line. We also plan on showing how easy it is to get around services like 

"Call Intercept" without even spoofing Caller ID. We will also be discussing why *67 and Complete 

Caller ID block features offered from the phone company are not adequate privacy protection as 

anyone can still get your phone number when you call them with your number blocked, we'll of course 

describe how this can be possible. As time permits there may very well be much more, you wont want to miss

this presentation.
