title: Connect landline phone to pc and retrieve number of incoming call
body: <p>I have made a simple php application which searches the details of people by inputting their phone number in the application. Now I want to extend its functionality that my landline phone is connected to my pc and whenever a call comes then the php application should fetch details of the related incoming number from database and display it. Now to implement this I need to get the number of that incoming call.</p>
  
  <p>How can I connect landline to my pc? (I think a phone modem will be required but I am not sure.)
  How can I get the number of that incoming call?</p>
