Any way to insert content from a widget field into a template?

I have a custom widget created where one of the fields is a full telephone number. It’s use is a call to action widget for the sidebar (e.g. enter the number, some text, a button URL, etc.). Is there any way to grab the content from this field (if it’s populated in the widget) and add it somewhere to a template? I want to add a phone number to the footer but instead of hardcoding it in the footer, I thought it’d be nice if it could just grab the number already entered in the call to action widget. Is this doable? Thanks.

Here’s my widget code:

add_action( 'widgets_init', 'sidebarctawidget' );

function sidebarctawidget() {
	register_widget( 'sidebarctawidget' );
}

class sidebarctawidget extends WP_Widget {

	function sidebarctawidget() {
		$widget_ops = array( 'classname' => 'sidebarctawidget', 'description' => __('A widget for the sidebar call to actions ', 'sidebarctawidget') );

		$control_ops = array( 'width' => 300, 'height' => 350, 'id_base' => 'sidebarctawidget' );

		$this->WP_Widget( 'sidebarctawidget', __('Sidebar Call to Action', 'sidebarctawidget'), $widget_ops, $control_ops );
	}

	function widget( $args, $instance ) {
		extract( $args );

		//Our variables from the widget settings.
		$title = apply_filters('widget_title', $instance['title'] );
		$text = $instance['text'];
		$prefix = $instance['prefix'];
		$number = $instance['number'];
		$fullnumber = $instance['fullnumber'];
		$url = $instance['url'];

		echo $before_widget;
		echo '<div class="sidebarcta">';

		// Display the title
		if ( $title )
			echo $before_title . $title . $after_title;

		//Display the text
		if ( $text )
			printf( '<p class="text">' . __('%1$s', 'sidebarctawidget') . '</p>', $text );

		//Display the text
		if ( $prefix )
			printf( '<span class="prefix">' . __('%1$s-', 'sidebarctawidget') . '</span>', $prefix );

		//Display the text
		if ( $number )
			printf( '<span class="number">' . __('%1$s', 'sidebarctawidget') . '</span>', $number );

		//Display the text
		if ( $fullnumber )
			printf( '<p class="fullnumber">' . __('(%1$s)', 'sidebarctawidget') . '</p>', $fullnumber );

		//Display the button and URL
		if ( $url )
			printf( '<a class="button" href="%1$s">' . __('Learn More', 'sidebarctawidget') . '</a>', $url );

		echo '</div>';
		echo $after_widget;
	}

	//Update the widget 

	function update( $new_instance, $old_instance ) {
		$instance = $old_instance;

		//Strip tags from title and name to remove HTML
		$instance['title'] = strip_tags( $new_instance['title'] );
		$instance['text'] = strip_tags( $new_instance['text'] );
		$instance['prefix'] = strip_tags( $new_instance['prefix'] );
		$instance['number'] = strip_tags( $new_instance['number'] );
		$instance['fullnumber'] = strip_tags( $new_instance['fullnumber'] );
		$instance['url'] = strip_tags( $new_instance['url'] );

		return $instance;
	}

	function form( $instance ) {

		//Set up some default widget settings.
		$defaults = array( 'title' => __('Get Connected TODAY!', 'sidebarctawidget') );
		$instance = wp_parse_args( (array) $instance, $defaults ); ?>
