Queued Call Consoles
Because an operator position cannot use a CTI application, a call to an operator QCC does not initiate screen pop. The call can initiate screen pop at a screen pop-capable extension when an operator transfers a call immediately, or during consultation, when the operator talks to the system user before transferring a call. The screen pop shows calling party identification information, if available, at the extension.
Direct-Line ConsolesA DLC either can function as an operator and unmonitored extension or can use a CTI application and function as a monitored extension. An unmonitored extension uses the telephone to transfer or conference a call.
A monitored DLC position functions like any other MLX extension that is using a CTI application. An outside call to the position initiates screen pop at the DLC extension. When a monitored DLC manually transfers or conferences a call, only the DLC extension number is passed to the destination extension or extensions.
In most respects, unmonitored DLCs operate like QCCs for screen pop. Calls to unmonitored DLCs do not initiate screen pop at the operator extension; when transferred or conferenced, they do initiate screen pop at a destination extension using a CTI application. Calls transferred from a DLC's programmed Cover button, however, do not initiate screen pop, even when the destination extension supports screen pop.
4400, 4400D, and Single-Line Telephones4400, 4400D, and single-line telephone extensions cannot take advantage of CTI applications.
