There is a possibility in asterisk to have a Listen Only option in a conference.
meaning only the Admin can speak, the rest only listen
I have implemented this myself
in page.conferences.php
<tr>
<td><a href="#" class="info"><?php echo _("listen only:")?><span><?php echo _("Make a Listen Only Conference)?></span></a></td>
<td>
<select name="opt#m">
<?php
$optselect = strpos($options, "m");
echo '<option value=""' . ($optselect === false ? ' SELECTED' : '') . '>'._("No") . '</option>';
echo '<option value="m"'. ($optselect !== false ? ' SELECTED' : '') . '>'._("Yes"). '</option>';
?>
</select>
</td>
</tr>
