I need to make a label containing a number clickable so when the user clicks the label a telephone number is called (or the option to call is shown to the user). When I click the label at the moment i just get a tooltip kind of menu with the option to copy the number...

```
private LabelField contactPhoneNumberField = new LabelField(number,Field.FOCUSABLE)
{
        protected boolean navigationClick()
        {
            // write your code on click
            // make the call
            PhoneArguments callArgs = new PhoneArguments(
                PhoneArguments.ARG_CALL, number);
            Invoke.invokeApplication(Invoke.APP_TYPE_PHONE, callArgs);
            return true;
        }

    };

```
