Telemarketing refers to using telephone operators to attract new customers and contact old customers to determine their satisfaction or whether they can accept orders. As far as the daily acceptance of orders is concerned, this is called telemarketing.

Many customers usually order goods and services by telephone. Distributors use all major media to provide direct services to potential customers. Newspapers and magazines have published a large number of advertisements selling books, electrical appliances, holiday services and other goods and services, and customers can call toll-free to order.
