I have a problem while adding phone number, I successfully added phone to Phone table but unable to view on front Contact section of User

long userId=user.getUserId();
        long classPk=(user != null ? user.getUserId() : 0);
        String className="com.liferay.portal.kernel.model.Contact";
        phone=ParamUtil.getString(actionRequest, "Phone");
        PhoneLocalServiceUtil.addPhone(userId, className, classPk, phone, "302",11011, false, serviceContext);
