How to deal with a GET variable of ‘name’?

Question

In case it’s useful for someone else in this situation, I ended up creating a page outside WordPress which renames the ‘name’ parameter (to ‘username’) and then redirects to the page I originally wanted to hit.

My code for this external page is:

<?php
$data = array('UID' => $_GET['UID'],
    'username' => $_GET['name'],
    'ANI' => $_GET['ANI'],
    'PIN' => $_GET['PIN'],
    'conferenceUID' => $_GET['conferenceUID'],
    'role' => $_GET['role'],
    'email' => $_GET['email'],
    'notes' => $_GET['notes'],
    'custom2' => $_GET['custom2'],
    'custom1' => $_GET['custom1'],
    'inboundAccessID' => $_GET['inboundAccessID'],
    'time_created' => $_GET['time_created'],
    'callinNumber' => $_GET['callinNumber']);

header( 'Location: http://www.example.com/registration-complete/?'.http_build_query($data) ) ;
?>
