The Computer Telephony Integration (CTI) API provides a communication channel between external systems, such as an Interactive Voice Recognition (IVR) system or a phone system, and Customer Service. This allows an external system to initiate a “screen pop” operation as part of incoming or outgoing phone calls. The CTI API is a licensed add-on.
See the Computer Telephony Integration API manual for more information about this interface. The manual includes documentation for the CTI API Properties option, where the API host name, port, and other properties are configured.
