this should work by putting that exact snippet as is in your theme functions.php file.

/**
* @param array $merge_tags
* @param MailChimp_WooCommerce_Order $order
* @return array
*/
function mailchimp_custom_order_merge_tags($merge_tags, $order) {
// the phone number can be used from either the shipping address, or the billing address.
//$shipping_phone_number = (string) $order->getShippingAddress()->getPhone();
$billing_phone_number = (string) $order->getBillingAddress()->getPhone();

// this is what I would do – only supply it if the phone number is there.
if (!empty($billing_phone_number)) {
$merge_tags[‘PHONE’] = $billing_phone_number;
}
// return the merge tags to be submitted.
return $merge_tags;
}

add_filter(‘mailchimp_get_ecommerce_merge_tags’, ‘mailchimp_custom_order_merge_tags’, 10, 2);

@edikitt, side question:
why do you use ‘wpcf7submit’ instead of ‘wpcf7mailsent’?

You probably want to track a submission event only when mail has been sent successfully
