Using an SIP IP Phone With Twilio

https://ertw.com/blog/2013/11/05/using-an-ip-phone-with-twilio/

I found Sean Walberg’s blog show how to connect SIP Phone to Twilio, I test it work for me.

But the Voice URL app only work for local call not international, I modify and add international dialing.


<?php
  $called = preg_replace(
  array('/sip:011?(.*?)@.*/', '/sip:1?(.*?)@.*/'),
  array('{$1}', '{$1}'),
  $_POST['Called']);
  header("content-type: text/xml");
  echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
  ob_start();
  var_dump($called);
  var_dump($_POST);
  $contents = ob_get_contents();
  ob_end_clean();
  error_log($contents, 3, "/tmp/twilio.txt");
?>
<Response>
  <Dial timeout="10" record="false" callerId="YOURTWILIONUMBER"><?= $called ?></Dial>
</Response>
