Can I intercept phone dialing?

Question

I would like to listen on the user's phone dialing. If I recognize that the dialed number is something that my app defined as a non-real-call (like starting with #####) I would like to cancel the call and start my own application. This is doable in Android. Can it be done on iPhone?

Thanks, Simon

I can see why you would want to to this. Eg dialing a special number to direct the call through an internet service instead of the main network.

It is not however possible on standard (ie non-jail-broken) iOS. You can get something similar with URL schemes.
