The article below has an interesting take on VoIP security. The article refers to a summary taken by the ACUTA, which is an organization consisting of colleges and universities. Last year, this survey cited VoIP security as its "biggest worry". This year, VoIP security was cited as a much smaller issue. The survey states that this is because economic worries now far outpace security issues. Why worry about security if you can't even pay for the VoIP system? This is pretty alarming trend. While VoIP systems are in some cases becoming more secure, as more deployments occur, the threat of attack will increase. It will be unfortunate if enterprises can't afford to address security.
