Does anyone know why HTTPS access is slow to my IP Phones? I am using PHP and CURL to perform a CGI/Execute and it is instant with http but with https it is slow (Takes just over 2 seconds to respond). Here is my code...
 
<?php

//Set the Variables used in the script
define('CUCM_PHONE_USER',    'pushuser');
define('CUCM_PHONE_PASSWORD',    'password!');

  $url = "https://192.168.1.8/CGI/Execute";
  $xml = "
  <startMedia>
    <mediaStream>
    <type>audio</type>
    <codec>G.722</codec>
    <mode>receive</mode>
    <address>239.0.0.1</address>
    <port>32000</port>
    </mediaStream>
  </startMedia>";

  $field = "XML=".urlencode($xml);

  $ch = curl_init();
  curl_setopt($ch,CURLOPT_URL,$url);
  curl_setopt($ch,CURLOPT_USERPWD, CUCM_PHONE_USER.":".CUCM_PHONE_PASSWORD);
  curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($ch,CURLOPT_SSL_VERIFYHOST, false);
  curl_setopt($ch,CURLOPT_POST,1);
  curl_setopt($ch,CURLOPT_HEADER,FALSE);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
  curl_setopt($ch,CURLOPT_POSTFIELDS,$field);

  $result = curl_exec($ch);

  curl_close($ch);

  echo $result;

?>
