Operator Consoles 

The system cannot have more than eight operator positions of any combination 
(QCCs and/or DLCs); if you use a combination of consoles, no more than four can 
be QCCs.

The Queued Call Console (QCC) is available only in Hybrid/PBX mode. In a QCC 
configuration, the system holds waiting calls in a queue and directs them to a 
QCC as a position becomes available. Only one call rings at a time.

The MLX-20L telephone is the only telephone that you can assign as a QCC. 
Unlike other users, the QCC system operator 

cannot

 use feature codes to activate 

features; however, the operator can choose features from the display and use the 
fixed features that have been assigned to the console buttons.

The display also tells the operator about incoming and outgoing calls: extension 
numbers and names (if programmed), trunk identifiers, reasons for call return and 
redirection, and the number of unanswered calls waiting for the operator’s 
attention.

The system automatically sets the buttons on the QCC with fixed features, and 
they are not programmable by the system operator or through centralized 
telephone programming. The QCC has the following fixed-feature buttons:

■

Call. Five buttons used to answer incoming calls and make inside and 
outside calls.

In Release 4.0 and later systems, the system manager can enable 
the Voice Announce to Busy feature on the fifth Call button (the 
factory setting is disabled). Then the QCC operator can use this 
button to voice announce a call to a user who can receive
