Phone mask with jQuery and Masked Input Plugin

I have a problem masking a phone input with jQuery and Masked Input Plugin.

There are 2 possible formats:

1. (XX)XXXX-XXXX
2. (XX)XXXXX-XXXX

Is there any way to mask it accepting both cases?

EDIT:

I tried:

$("#phone").mask("(99) 9999-9999"); 
$("#telf1").mask("(99) 9999*-9999");    
$("#telf1").mask("(99) 9999?-9999"); 

But it doesn't works as I would like.

The closest one was (xx)xxxx-xxxxx.

I would like to get (xx)xxxx-xxxx when I type the 10th number, and (xx)xxxxx-xxxx when I type the 11th. Is it posible?

Try this - http://jsfiddle.net/dKRGE/3/

$("#phone").mask("(99) 9999?9-9999");

$("#phone").on("blur", function() {
    var last = $(this).val().substr( $(this).val().indexOf("-") + 1 );

    if( last.length == 3 ) {
        var move = $(this).val().substr( $(this).val().indexOf("-") - 1, 1 );
        var lastfour = move + last;
        var first = $(this).val().substr( 0, 9 );

        $(this).val( first + '-' + lastfour );
    }
});
