Computer telephony integration, also called computer–telephone integration or CTI, is a common name for any technology that allows interactions on a telephone and a computer to be integrated or coordinated.

What is the meaning of computer telephony integration?

Computer telephony integration (CTI) means coordinating a computer with a telephone system, and using the computer (perhaps even a desktop machine) to perform the call control functions usually associated with a PBX or Key System (key systems are sometimes called "six-button telephones").

How does computer telephony integration work?

Computer telephony integration, an abbreviation for CTI, is a way to control the functionalities of the phone with the computer. Which means that all telephone calls, which simply go through the PBX or a key system telephony, can be made via the desktop and the telephone is no longer needed.
