Information, Computer and Network Security Terms Glossary and Dictionary

VAM (voice or VoIP spam), also known as SPIT (spam over Internet telephony), is unsolicited bulk messages broadcast over VoIP (Voice over Internet Protocol) to phones connected to the Internet. Although marketers already use voice mail for commercial messages, IP telephony makes a more effective channel because the sender can send messages in bulk instead of dialing each number separately. Internet phones are often mapped to telephone numbers, in the interests of computer-telephony integration (CTI) but each has an IP address as well.
