Phone Home runs in the background, allowing you to disable your computer from anywhere in the world in case it is stolen.
At a user-defined time, Phone Home dials a selected telephone number, preferably your own telephone number or the number from which the modem is dialing.
If your computer has been stolen, you can get the thief's caller ID. In most countries, if you don't subscribe to Caller ID, you can still dial a number to hear some information about the last caller.
The program is TAPI-compliant and includes password protection.
