Facetime chat for a noob?

[ant]

I have a camera and microphone attached to my MM. I want to facetime/video chat with someone in another room using my PC or Phone. The MM has no mouse/keyboard/or buttons so the mirror needs to auto answer and pop up a video stream of me and send me a video stream of them all with zero interaction from the person standing infront of the mirror. Then when I hang up it needs to close the video chat window and go back to the regular MM screen. Is this possible? Or is it really complicated to configure?
