The data param is supposed to be an object that has keys and values.

var data = {
    hiddenContact: document.getElementById('hiddenContact').value
}
$.post('/callcenter/admin/postContacts', data);

Then in PHP you can retrieve it like this:

$hiddenContact = $_POST["hiddenContact"];

I'm not a big CakePHP user but I believe the CakePHP version is like this:

$hiddenContact = $this->params["hiddenContact"];
