I think my application goes into the background when the call starts.

This is not possible with the official SDK. The best you can do is determine if the user is in a call. You can do this by checking the frame size of the status bar.

[UIApplication sharedApplication].statusBarFrame

If you ask if you can track phone calls in the background, you cannot in any situation.

, , , . currentCalls 'CTCallCenter', .

, , callEventHandler 'CTCallCenter'.

It is not possible to get this information with the current SDK, most likely for privacy reasons. I would recommend filing a feature request with Apple (http://radar.apple.com), however I doubt what they might include in the future.
