Change state of call in iOS4

Is it possible we can change state of call from CTCallStateIncoming开发者_如何学JAVA to CTCallStateConnected with in an iOS4 app using CTelephony framework.

No, I believe these are getters, not setters. Which makes sense because an app shouldn't be interfering with phone functions. Your app is secondary to any incoming call, which is why it's put in a dormant state when calls come in.
