Delphi and telephone application

Delphi people,

I am looking for a component or indeed tips, on how to make an application that will call a certain telephone number, drop the line when the connection is broke, (even if the cable is pulled out of the modem).

The applications I built have all time limited components or pop up reminders, my company is looking for something where you just turn on the computer and the app will run by itself.

The components I use don't detect if the cable is pulled out of the back.

Any ideas anyone?

High points!
