Cold calling is the solicitation of business from potential customers who have had no prior contact with the salesperson conducting the call.[1][2] It is an attempt to convince potential customers to purchase the salesperson's product or service. Generally, it is an over-the-phone process, making it a form of telemarketing,[3] but can also be done in-person by door-to-door salespeople. Though cold calling can be used as a legitimate business tool, scammers can use cold calling as well.
