A communications terminal, a system and a method for internet/network telephony

The invention relates to an electronic communication terminal is voice-over-IP, comprising an audio apparatus, is provided based on the first electric signal sound reproduction, and sound recording to generate the second electric signal, a switch device, is used to the second electric signal conversion according to represent the sound transmission of the appropriate data transmission format's data, and sound of the representative received with a data format for receiving data to a into the first electric signal, and communication device, is carried out to the wireless near-field communication for receiving and transmitting data in the connection element; the connection element is provided with a network and/or InternetConnection, wherein the terminal further - comprising protocol device, is provided, the wireless near-field communication to act according to a TCP/IP protocol processing control/to the receiving and transmitting data communication. The provides a communication terminal, comprising in a network and/Internet for digital voice and sound, waits substrate-processing, wherein obtained very high economy to save. At the same time, and/or a wireless network communication module is connected with the network no need to specific device and function, then the flexible. The invention in addition to a system and method for voice-over-IP, relates to a j-shaped to make the end of the method for computer is connected to the computer-readable medium.
