CTI = Computer Telephony Iintegration
CTI allows a computer to interact with the telephone, e.g. in set up, and terminate calls with numbers taken from a directory via a PC application.
There are basically two different approaches supported with CTI:
- The computer (e.g. a PC located at the same desk as the telephone) directly interacts with the telephone: First Party CTI.
- The computer (could also be a co-located PC) interacts with the telephone system (e.g. SIP application server), and the latter controls the telephone: Third Party CTI.
