Abstract
An Internet/telephone adapter device and method is provided to automatically detect the communication type of an incoming call. The Internet/telephone adapter device comprises an auto-detecting means for providing a mechanism to detect the communication type of an incoming call by means of the feature rings. The feature rings have a predetermined feature distinguishable from non-feature rings. Whenever the auto-detecting means determines the communication type of the incoming call, it sends a control signal to CPU. In response to the control signal, the CPU will automatically switch the linkage to the Internet or to the PSTNs without further human operations.
