When a customer give Call Request from the site without their email address it can't be placed as order. If the customer give both phone number and email address then it looks ok. The problem is that most of our customer give only the phone number then we call and mostly placed order finally. Now when the customer placed order then we need to entry details manually again.
Is it possible to enable the Call Request without email address as placed as product order? If not possible how to make email address as mandatory field with the Call request option.
