UDP Features
In Release 6.1 and later systems, Service Observing cannot be
programmed on a CTI link. Extensions serving as CTI links cannot be
programmed as Service Observers nor as members of Service Observing
groups. If an extension is programmed as a CTI link, it is removed as a
Service Observer or a Service Observing group member.
CTI user (client) extensions can be Service Observers as well as
members of Service Observing groups.
The Service Observer cannot use a CTI application (such as Passageway
Telephony Services or Passageway Direct Connect) while actively
observing an extension.
CTI allows software on a worktop application to control the following:
Placing a call on hold
Retrieving a call from hold
Inside transfer and three-party conference
Answering
Hanging up on the SA buttons of an extension using the application
When the dial plan changes, the applications must use the new extension
number in any request. The PassageWay Telephony Services security
database should be updated with the dial plan changes so that
permissions are set for the new extension numbers and cleared for the
old extension numbers. Some settings in the CTI software applications
may need to be updated as well.
CTI link applications can control inside transfers, not transfers to outside
numbers. When a CTI application is used to initiate a transfer, caller
information is passed to a screen-pop-capable destination.
When a transfer is initiated manually, using the telephone at an extension
where a CTI application is installed, screen pop is not initiated at a
screen-pop-capable destination, even if the CTI application is used to
complete the transfer.
A transfer by a QCC or unmonitored DLC operator generates screen pop
of inside or outside caller information at screen-pop-capable destinations.
In Release 6.0 and later systems (Hybrid/PBX mode only), operation for
non-local dial plan extension calls, both incoming and outgoing, in
PassageWay Telephony Services applications depends upon the
application implementation, the type of private networked trunk (PRI or
tie) that carries calls, and how the call. See
