NEC Corp. has developed technology that can help prevent spam phone calls to voice over Internet Protocol (VoIP) users.

According to a ComputerWorld.com report, the company plans to demonstrate the technology at the 3GSM World Congress in Barcelona but still has more work to do before it can sell a commercial product. The technology discovers whether a caller is a human or a machine by testing the machine's capability to perform human-like conversation. Once the technology determines that a machine has made the call, it blocks the connection, preventing the user's phone from ringing. NEC has developed the technology so that new modules can quickly be added to the system to respond to new and different kinds of VOIP spam.
