The traditional caller ID information phone only displays the data on its own phone, but cannot provide the data to the computer or other devices. Therefore, it is very necessary to develop the interface between the caller ID phone and the computer and the related data collection system, and it is also of practical value.

The device is divided into four sub-module designs, namely caller ID signal decoding module, signal acquisition module, telephone signal processing module, and USB transmission module. The USB transmission module is called through the interface function, and the caller ID number can be obtained through the interface function.
