CTI (Computer Telephony Integration) Link Feature

Description

Basic Call Control

A CTI application on your PC can control an extension's SA button operations. No other buttons (for example, Personal Lines) are monitored by applications or are allowed to perform the CTI services. Basic call control includes:

• Answering calls arriving on an SA button
• Making calls from an SA button
• Hanging up calls
• Holding and retrieving a call on hold your extension
• Inside transfer
• Three-party conference, including those conferences where one or two parties are outside the system

A conferee in the non-local dial plan is considered to be outside the system. If you are on a PassageWay Telephony Services client extension with a call on an analog Centrex loop-start line, and you attempt to transfer that call to an extension with Centrex Transfer via Remote Call Forwarding activated, the call is immediately transferred without consultation. The originator is disconnected

CTI applications vary in how they use the system's features. The list of basic call control activities includes the functions that a CTI application may control; a given application does not necessarily use these system features.

DLC operator extensions can use CTI applications, although QCCs cannot. If a DLC's SA button operations are controlled by a CTI application, caller information is passed on to a three-way conference or transfer destination, as long as the operator uses the application to perform the transfer or conference. (The DLC extension works as any other screen pop-capable extension does.) If a DLC operator's SA calls are not controlled by a CTI application, then caller information for transferred or conferenced calls is also passed on to a screen pop-capable extension, just as with a QCC. The only exception occurs when a call is transferred from a Cover button on a DLC. In this case, there is no screen pop at the destination extension.

The display of incoming and outgoing calls from and to non-local extensions depends upon the PassageWay Telephony Services application, the private network trunks, and how the call is routed. For more information, see Private Network Operation.
