I am planning to make a project in which I want to show mobile communication and want to monitor them through my PC. But I am facing a problem i.e. I am nt sure how I can actually control my mobile to make a call.

Basically I want to connect two mobiles to a micro-controller using RF transceivers. One RF transceiver for one phone and one for another and both RF transceivers connected to the micro-controller.
Then I want this micro-controller to act as a switching element.

How can this be done? Can anyone give me some ideas.

I also want to know, how can i use a control signal of a particular frequency to initiate phone service when it's switched ON.
