Intro to SIP hacking slides from the 22nd Chaos Communication Congress “Within the last year VoIP devices and applications flooded the market. SIP (Session Initiation Protocol) became the industry standard although it’s still under constant development. VoIP networks converge with the PSTN and thus offer ways and means for new (and old) attacks. The talk gives a brief introduction on how various components in the VoIP universe interact. The main part deals with implementation problems within SIP in both end user as well as ISP site devices and applications.” [via] Link.

The goal was to use as few parts as possible while adding as many useful features as possible.” Link.There are also more electronic project on the main sectionof the site.” Thanks JasonR!
