• create Application extension for background service
• implement PhoneListener
• use callInitiated
• must be signed before using on the device
• should be tested against a known issue

Sample code:

import net.rim.blackberry.api.phone.Phone;
import net.rim.blackberry.api.phone.PhoneListener;
import net.rim.device.api.system.Application;
import net.rim.device.api.ui.component.Dialog;

public class CatchCall extends Application implements PhoneListener {
    public CatchCall() {
        Phone.addPhoneListener(this);
    }
    public static void main(String[] args) {
        new CatchCall().enterEventDispatcher();
    }
    public void callAdded(int callId) {
    }
    public void callAnswered(int callId) {
    }
    public void callConferenceCallEstablished(int callId) {
    }
    public void callConnected(int callId) {
    }
    public void callDirectConnectConnected(int callId) {
    }
    public void callDirectConnectDisconnected(int callId) {
    }
    public void callDisconnected(int callId) {
    }
    public void callEndedByUser(int callId) {
    }
    public void callFailed(int callId, int reason) {
    }
    public void callHeld(int callId) {
    }
    public void callIncoming(int callId) {
    }
    public void callInitiated(int callid) {
        Dialog.inform("call initiated");
    }
    public void callRemoved(int callId) {
    }
    public void callResumed(int callId) {
    }
    public void callWaiting(int callid) {
    }
    public void conferenceCallDisconnected(int callId) {
    }
}

      

        
        
        
      

    

Cancel call

You can use an event to start a fire. Click the close button:

public void dropCall()
{
    KeyEvent inject = new KeyEvent(KeyEvent.KEY_DOWN, Characters.ESCAPE, 0);
    inject.post();
}

      

        
        
        
      

    

Don't forget to set permissions for device release: Options => Advanced options => Applications => [Your app] => Change default permissions => Interactions => key stroke Injection
