Preview Dialing initiates the establishment of the telephone connection from the call agent. Unlike the other two methods, the call agent determines when the preview dialer should make the next telephone connection. In general, the call agent uses the time between two calls by preparing for the call based on information about the caller that is displayed on the caller's screen. Thanks to better call preparation, the call agent can respond directly to the customer's needs or possible complaints and thus conduct his call in a more concentrated and faster manner. As a rule, with more chances of success.
