PROBLEM:
We need to log out phone calls in and outlet of the company

How we wanted to do it:
Use node.js to read the serial port from the phone system then store the data into the MsSQL database

Eventual solution:
1) Read serial port
2) store in local MySQL database
3) every 3 minutes create a CSV file containing the last 3 minutes of calls and store on a Windows shared directory
4) have a access 2000 programme collect these files every 30 minutes
5) insert into MsSQL database
