A CTI Port is a virtual port. It is analogous to a trunk line in a traditional ACD or PBX setting. i.e The CTI Port allows access to the Post Routing capabilities of the IP-IVR.
A CTI Route Point is a virtual device that can receive multiple simultaneous calls for the purpose of application-controlled redirection. Once a CTI Route Point has been created, lines (directory numbers) can be added and configured. Applications that use CTI route points include the Cisco IP Interactive Voice Response (IP-IVR) system and Cisco JTAPI with ICM. Calls are directed to CTI Route Points, which subsequently route the call to an available CTI port, the front end of the application. A CTI Route Point is the number a caller dials to access the application. A CTI Route Point must be configured for each application.
