如果在这种情况下对其他人有用，我最终在WordPress之外创建了一个页面，该页面将“name”参数重命名为“username”，然后重定向到我最初想要点击的页面。

此外部页面的代码为：

<?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) ) ;
?>
