Communication system

Abstract

A communication device capable of receiving, processing and sending analog signals, characterized in that the device is coupled to the audio input/output ports of a built-in or external sound attached to a computer, through standard audio plugs. The device may be installed as a stand-alone unit between the audio board and a telephone line, or as a part of the audio board. During its operation the device is constantly under the control of software operating in the computer side. Signals entering through the audio inport and digitized, filtered, and analyzed by software modules, and the software then manages the information-outputs information and/or saves voice massage, etc.-in accordance with contents of these signals.

1 . A method for providing telephone communications in cooperation with a host computer, said method comprising: 
 processing an audio signal by said host computer;    generating a control signal by said host computer according to said processing step;    sending said control signal to a DTMF decoder and providing first signals representative of DTMF signal in response to the control signal to a logical unit;    controlling a data access arrangement with said logical unit according to said control signal;    routing said audio signal through a mixer; and    interfacing said audio signal to a telephone line using said data access arrangement.
