Voice Over Internet Protocol (VOIP)

Voice over Internet Protocol (VoIP) is based on an IP standard that is capable of transporting voice and data packets over the same network. Unlike circuit-switched networks, IP doesn’t require a dedicated connection for an entire call. Voice signals are converted to packets that are sent across the network and reassembled in the correct order when they reach their destination. VoIP services can be deployed over the Internet or private IP networks (LAN/WLAN).
