The video is the slides from when Kevin Mitnick gave a talk on how to unmask caller-id @ last hope 2008. It shows the usage of a technique used with Asterisk while using service from Flowroute.com. The voice overs are done by me, hopefully this explains it a bit better than just having the video!
I can't post the code up in the description for some reason, so please visit my blog for an explanation:
