title: Change faker gem phone number format
body: <p>Is there a way to control the format of the Phone number generated by faker? </p>
  
  <p>When I call:</p>
  
  <pre><code>Faker::PhoneNumber.cell_phone.to_i
  </code></pre>
  
  <p>I end up getting the wrong value. </p>
  
  <p>I also would like to not have extensions.</p>
