Hundreds of IT directors and telecoms managers attended security roadshows organised by Siemens Communications across the UK in the past few weeks. The events listed the new threats to voice over IPsystems.
These included attack by the widely available freeware known as Vomit, which can capture packets of voice data from converged voice and data networks, allowing hackers to listen to private conversations.
There is also a threat called signal protocol tampering. Hackers plug a laptop into a network to "sniff" packets of data, selling them on to criminals to make free phone calls remotely via a network switch.
