How to sort Phone Numbers?

Hi Friends,

I have developed button click to open Android contact list then contact select to show phone number in my tableview. The problem is some contact users having only email id so if i select that email person after i can't see anything in my tableview. I want to sort phone numbers first the finally shows only email users in my device contact book.

customNavigation.addEventListener('AddButtonPressed', function(e) {
 
            Ti.Contacts.showContacts(values);
 
    });
