title: Faker generating strange phone numbers?
body: <p>So I'm creating a database with Laravel and seeding it, and I ran into an issue where it generates a phone number as follows: <code>(635) 889-5802 x45134</code>. This causes issues by exceeding the desired length of the database column. </p>
  
  <p>So my questions are:</p>
  
  <ol>
  <li>On a practical level, why does it do this? What is the real-world use case of <code>x#####</code>? I'm looking around and can't find a good explanation, best guess is an internal organization extension. </li>
  <li>When building an application where internationalization might eventually be important, is it a good idea to build in support for whatever these are? If so, then expanding the column width would be a better solution for me. </li>
  <li>If this isn't important, is there a way to prevent these <code>x#####</code> from being attached to the number on generation? I feel like this should be an option. If not it sounds like my best options would be a custom provider or a regex filter to remove these values. </li>
  </ol>
