VoIP applications convert analogue voice signals into a digital format, which is then encapsulated into IP packets for transmission over the Internet. Our research has examined both the security and privacy implications of widespread adoption of VoIP for personal and business telecommunications and also the use of VoIP calls by criminals, as many implementations of VoIP may also use strong encryption to secure both the voice payload as well as to control messages. We have also considered the implication of recovering electronic evidence and information from VoIP since conventional methods of eavesdropping and wire-tapping do not apply to VoIP calls.
