Try this code. Sure it will help for you. Its working fine for me.

public class PhoneStatReceiver extends BroadcastReceiver{        

    private static final String TAG = "PhoneStatReceiver";
    private static boolean incomingFlag = false;
    private static String incoming_number = null;

    @Override
    public void onReceive(Context context, Intent intent) {
            if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){
                    incomingFlag = false;
                    String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER); 
                    Log.i(TAG, "call OUT:"+phoneNumber);
            }else{
                       TelephonyManager tm = 
                        (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);
                    switch (tm.getCallState()) {
                    case TelephonyManager.CALL_STATE_RINGING:
                            incomingFlag = true;
                            incoming_number = intent.getStringExtra("incoming_number");
                            Log.i(TAG, "RINGING :"+ incoming_number);
                            break;
                    case TelephonyManager.CALL_STATE_OFFHOOK:
                            if(incomingFlag){
                Intent callIntent = new Intent(context, RecordService.class);
                context.startService(callIntent);
                                    Log.i(TAG, "incoming ACCEPT :"+ incoming_number);
                            }
                            break;
                    case TelephonyManager.CALL_STATE_IDLE:
                            if(incomingFlag){
                context.stopService(new Intent(context, RecordService.class));
                                    Log.i(TAG, "incoming IDLE");
                            }
                            break;
                    } 
            }
    }
