A call centre (Commonwealth spelling) or call center (American spelling; see spelling differences) is a managed capability that can be centralised or remote that is used for receiving or transmitting a large volume of enquiries by telephone. An inbound call centre is operated by a company to administer incoming product or service support or information inquiries from consumers. Outbound call centres are usually operated for sales purposes such as telemarketing, for solicitation of charitable or political donations, debt collection, market research, emergency notifications, and urgent/critical needs blood banks. A contact centre is a further extension of call centres' telephony based capabilities, administering centralised handling of individual communications including letters, faxes, live support software, social media, instant message, and email.
A call centre was previously seen as an open workspace for call centre agents, with workstations that included a computer and display for each agent and were connected to an inbound/outbound call management system, and one or more supervisor stations. It can be independently operated or networked with additional centres, often linked to a corporate computer network, including mainframes, microcomputer, servers and LANs. It is expected that artificial intelligence-based chatbots will significantly impact call centre jobs and will increase productivity substantially. Many organisations have already adopted AI-based chatbots to improve their customer service experience.
