VoIP has long been held up as the biggest threat to the revenue streams of traditional telephony operators, but a new report argues that VoIP over instant messaging (VoIM) poses a much bigger threat.

VoIP mimics traditional telephony in that it is means of establishing a voice conversation between, generally, two parties across a telephone network: sometimes between PCs and sometimes between telephone handsets. VoIM on the other hand provides the voice communication as one component of a real time communication system based around the PC.
