You can only use this feature if you have set up your MobileMe account in the Setting app on your iPhone. If you never did this, you will not be able to locate your phone. If you have set it up and need to use it to find your iPhone, you can use another iOS device with the Find My iPhone app installed to locate it. From there, you can see where it is on a Google map, remote lock the iPhone, remote wipe the iPhone, display a message on the screen, or have the iPhone sound an alarm so you can locate it easier (plays the sound at maximum volume even if silent switch is enabled!).
If you are using a Mac, you can download the FaceTime app of the Mac App Store (You may need to update you Mac Software If you do not have a Mac App Store). On a iPhone 4 or iPhone 4S to FaceTime select the contact you want to call in the Phone App or in the Contacts App. Instead of taping on their phone number, scroll down and you will see a button that says FaceTime. You must be connected to a Wi-Fi to use FaceTime.
I am not sure why your iPhone is not letting you face time. I would try uninstall the app and re-install the app to see if it will help.
