Hello to everyone,I am experiencing a problem with a project I am currently developing.

I can not get the msisdn info , although the provider has enabled msisdn forwarding for my domain

I use the code below, my server is Apache


<?php
error_reporting(0);
apache_request_headers(1);
$t1=$_SERVER['HTTP_USER_AGENT'];
$t2=$_SERVER['MSISDN_ATTRIBUTE_NAME'];
$t3=$_SERVER['X-Nokia-msisdn'];
$t4=$_SERVER['IMSI_ATTRIBUTE_NAME'];
$t5=$_SERVER['X-Nokia-msisdn'];
$t6=$_SERVER['REQUEST_METHOD'];
$t7=$_SERVER['QUERY_STRING'];

All I need is to get the msisdn value, but i can't

I can get the user agent value and the method value

Any suggestions ?
