Voice over IP is a dream concept for companies and organisations all over the world. With voice calls being sent over the internet, money can be saved on long-distance calls and intra-office calls.

VoIP can also help companies economise through managing only one converged data network instead of separate voice and data lines and it can also bring multimedia services to the desktop, in some cases improving customer service.

A computer can pass the Turing Test if it can fool a human being - through its responses in a conversation - into thinking that it is human. NEC's VoIP spam detector claims to be using a computer to determine whether a caller is human or a machine. Quite an achievement!

This is especially so since, according to Wikipedia, no computer has yet passed the Turing Test, which was devised by computing genius Alan Turing in 1950.
