CTI (Computer Telephony Integration) is a communication solution with which the phone can be controlled from a PC.

Coupling the phone and PC enables additional functions to be used. These improve the efficiency of communications in a company and ensure improved exchange of information.

With it, for example, contacts can be selected from a database and called directly by clicking with the mouse. Missed calls are displayed directly on the PC, and a recall can be triggered by clicking with the mouse.

In COMfortel® D-series devices, Action URL is used to implement CTI.
