A contact center offers omni-channel services that support phone answering calls for businesses and organizations. It works as a vocal communication channel by means of cloud-based operations. Agents are trained to assist clients by providing customer support, inbound and outbound calls, generating leads, tech and product support, processing back-office applications and more. There are three types of contact centers: inbound, outbound, and virtual. An inbound center provides agents who receive calls from customers, while outbound center agents call potential or existing customers. Virtual call centers combine those services with advanced features.
