Personal Speed Dial and System Speed Dial cannot be used to dial numbers on
a QCC. The Directory features can be used instead.
When a QCC system operator arranges a 3-party conference (the system
operator and two other participants) and presses the Release button, the QCC
system operator is released from the call and the other two participants remain
connected. Although this process is similar to a transferred call, the system
operator's extension remains on the SMDR record.
System Access buttons are not assigned on a QCC. The QCC system operator
uses Call buttons to make and receive inside and outside calls.
The Listed Directory Number (the extension number for the QCC queue) can be
renumbered. The factory-set extension is 800.
The QCC system operator uses the Start and Release buttons or a DSS button
to transfer calls. However, pressing the Transfer button on a QCC console is the
same as pressing the Start button. A system operator cannot make or receive
voice-announced transfers. When a QCC system operator uses the Start and
Release buttons to transfer a call, the Return Ring Interval applies for transfer
return timing instead of the Transfer Return Interval.
Voice announcements are cancelled on QCCs and cannot be activated. Voice-
announced transfers cannot be made from the QCC.
