The use of toll-free telephone numbers that customers call to obtain information about products and make purchases is referred to as

Inbound telemarketing.

Explanation:

An inbound telemarketing can be defined as a marketing strategy which involves having customers call in to initiate the first point of contact for the purchase of goods and services offered by a business firm.

Generally, inbound telemarketing is mainly based on customers calling in to initiate a business transaction with a company unlike an outbound telemarketing where the company is responsible for reaching out or calling customers to buy their goods and services.

In inbound telemarketing, the company provides contact numbers to customers through advertisements, websites, flyers, billboards etc.

Hence, the use of toll-free telephone numbers that customers call to obtain information about products and make purchases is referred to as inbound telemarketing.
