Contact Form 7 Multi-Step Forms process form fields

I have implement this as a 5 step process and all working fine.

When the form completes the email with all the fields is send successfully

I also need to separately process the form data to a webservice.

I have a filter function in function.php to get all

function bebri_wpcf7_save_data()
{
if(!isset($_POST[‘_wpcf7’])) {
return;
}
wp_saveQuote($_POST);
}
add_action( ‘wpcf7_posted_data’, ‘bebri_wpcf7_save_data’ );

The function is call ok but the $_POST data passed to my function seems to only contain the fields on the last form step not the all the form fields.
