Performing quality test calls using an Android app

I need to perform tests to verify the ability of my mobile operator to correctly deliver the caller id (the number associated to my SIM) to the called device. I noticed that when I am abroad I often see on my phone a number different from that which made the call, like as somebody modified the caller ID of the call.

I'd like to develop an APP for Android device that is able to verify this kind of behavior.
The process is simple:
- I ask my mobile operator for a second number to be associated to my SIM card
- I install on my phone an App that is able to intercept calls received on the second number, to make the phone not to ring and to take note of the calling number received
- I ask somebody to make calls from Italy to the second number when I am abroad
- When I come back to Italy (or when the phone is under WIFI coverage) the App send the logs to a server where I can make analysis.

Is Android enough open to create an APP's like that (intercepting calls, not ringing, not anwering and taking note of the caller)?

Thanks
bye
