Within the last year VoIP devices and applications flooded the market. SIP (Session Initiation Protocol) became the VoIP 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. Features like Caller-ID presentation and billing suddenly can be turned against an ISP for fun and profit.
