CTI, or Computer Telephony Integration, is a technology that allows for the seamless integration of telephone systems with computer systems. This integration enables users to access and manipulate telephony features, such as making and receiving calls, through their computer interface. CTI has revolutionized the way businesses communicate, providing a more efficient and streamlined approach to handling phone calls. It has also opened up new possibilities for customer service, sales, and marketing, as it allows for the integration of customer data and call analytics. With CTI, the traditional telephone has evolved into a powerful tool that enhances productivity and improves communication in the digital age.
