A method to implement CID enhancement performed by mobile phone software, running on a user/subscriber's mobile phone, in communication with a response server of a Website during an incoming call. The method includes alerting the Website by transmission of an initiation command from the mobile phone upon receipt of the incoming call, extracting the caller number from the phone ringing feature of the mobile phone, connecting the mobile phone over the Internet to the response server and responding to the initiation command, such that the caller's ID is displayed with said relevant caller information and said other caller data in real time, and is provided within the few seconds elapsed before the user/subscriber answers the phone call.
