When a customer calls a call center, CTI (Computer Telephony Integration) screen pop is a process that allows the agent to automatically view the customer’s information on their workstation, thanks to the caller’s phone number. This process derives its name from the integration of telephony and computer systems, a practice established at a time when telephone communications were not fully computerized and required a dedicated CTI server. To illustrate this functionality, we can refer to a concrete example of CTI screen pop.
