This function only works on Window-based computers.
Computer telephony integration, also called computer–telephone integration or CTI, is technology that allows interactions on a telephone and a computer to be integrated or coordinated. For all incoming calls, the Agent is given the choice to create a call log to which a Requester can be connected. The call logs can also be connected to Tickets.
The incentive for the function I to keep track on how many calls are handle and the durations of these.
