A voice Internet transmission system which enables a person to have a conversation via the Internet without having to use a computer at either end of the conversation, and without incurring long distance telephone charges regardless of the distance between those having the conversation. In a preferred embodiment, the apparatus consists of two nonInternet capable devices being enabled to connect to the Internet and either in duplex or simplex mode transmit packets of Internet formatted data comprising digitized, compressed and encrypted conversation between the devices. In other words, a person can pick up an ordinary telephone and converse with another person, regardless of the distance between them, without incurring long distance telephone charges. No special telephone is required, nor is a computer running special software. The apparatus which makes this possible is a system of Internet access nodes or VoiceEngines. These local Internet VoiceEngines provide digitized, compressed, and encrypted duplex or simplex Internet voice/sound.
