How to add (and save) checkbox to custom meta box

I have input the following code to create a custom meta box for a site I’m building. However, I can’t seem to get the checkbox to save after clicking “Publish” or “Update”. I’ve tried several different variations of code from different sources on how to tackle it, but they seem to not match up with what I’m doing, and therefore have no effect. If anyone can assist in telling me what to add/change to get it to work, I’d greatly appreciate it!

// The Contact Metabox
	function cg_contact() {
    	global $post;

    // Noncename needed to verify where the data originated
    echo '<input type="hidden" name="contactmeta_noncename" id="contactmeta_noncename" value="' .
    	wp_create_nonce( plugin_basename(__FILE__) ) . '" />';

	// Get the contact data if its already been entered
    $phone1 = get_post_meta($post->ID, '_phone1', true);
	$phone2 = get_post_meta($post->ID, '_phone2', true);
	$fax = get_post_meta($post->ID, '_fax', true);
	$emailaddr = get_post_meta($post->ID, '_emailaddr', true);
	$websiteaddr = get_post_meta($post->ID, '_websiteaddr', true);
	$directlink = get_post_meta($post->ID, '_directlink', true);
    // Echo out the field ?>
    <table width="100%">
    	<tr>
        	<td style="padding-right:10px;">
			<?php echo '<p>Phone 1:</p>';
			echo '<input type="text" name="_phone1" value="' . $phone1  . '" class="widefat" />';?>
            </td>
            <td style="padding-right:10px;">
			<?php echo '<p>Phone 2:</p>';
			echo '<input type="text" name="_phone2" value="' . $phone2  . '" class="widefat" />';?>
            </td>
            <td>
			<?php echo '<p>Fax:</p>';
			echo '<input type="text" name="_fax" value="' . $fax  . '" class="widefat" />';?>
            </td>
        </tr>
        <tr>
        	<td style="padding-right:10px;">
            <?php echo '<p>Email Address:</p>';
			echo '<input type="text" name="_emailaddr" value="' . $emailaddr  . '" class="widefat" />';?>
            </td>
            <td style="padding-right:10px;">
            <?php echo '<p>Website:</p>';

            </td>
            <td>
            <?php echo '<p>Direct Link?</p>';
			echo '<input type="checkbox" name="_directlink" class="widefat"'. checked( $check, 'on' ). '/>';?>
            </td>
        </tr>
    </table>
