jQuery validation of NANP Phone numbers

Question

I'm trying to validate my form. In my form is a phone number field. The user inserts a phone number and validation takes place as well as formatting. I've read a lot of the other similar questions in StackOverflow and through searches elsewhere, but I'm stuck. The form keeps saying that a valid number I insert is invalid.

I'm only concerned with NANP numbers and I understand the NANP numbers are formatted like this: NXX-NXX-XXXX, where N can only be digits [2-9], and X can be [0-9]. I don't need a country code.

Here's my code:

function validatePhone(){
    var error = 1;

    var hasError = false;
    var $this = $(this);
    var regex1 = /^(\()?[2-9]{1}\d{2}(\))?(-|\s)?[2-9]{1}\d{2}(-|\s)\d{4}$/;

    phone = $(this).val();
    phone = phone.replace(/[^0-9]/g,'');        
    if(!regex1.test(phone)){
        hasError = true;
        $this.css('background-color','#FFEDEF');
    }   
    else{
        area = phone.substring(0,3);
        prefix = phone.substring(3,6);
        line = phone.substring(6);
        $this.val('(' + area + ') ' + prefix + '-' + line);
        $this.css('background-color','#FFFFFF');    
    }

The idea is that no matter whether I insert 8012559553, (801)2559553, (801)255-9553, 801-255-9553 or something similar that it would be validated and formatted like this: (801) 255-9553. But again, the form for some reason continues to say that any number I insert is invalid, regardless of whether it's valid or not. This is code that I was using that was working, but didn't comply with NANP formats:

function validatePhone(){
    var error = 1;

    var hasError = false;
    var $this = $(this);
    phone = $(this).val();
    phone = phone.replace(/[^0-9]/g,'');        
    if(phone.length != 10){
            hasError = true;
            $this.css('background-color','#FFEDEF');
    }   
    else{
            area = phone.substring(0,3);
            prefix = phone.substring(3,6);
            line = phone.substring(6);
            $this.val('(' + area + ') ' + prefix + '-' + line);
            $this.css('background-color','#FFFFFF');    
    }

So, I'm having trouble implementing the regex test of the numbers to make sure that the numbers are real and then have the number formatted correctly... Any ideas?
