make inside and outside calls.)
Calls are delivered to the QCC operator in first-in first-out order, according to
the queue priority level assigned to each type of call. If more than one QCC
operator is available, the operator who has been idle the longest receives the
call.
Both inside and outside calls ring on Call buttons on the QCC. Unlike the
Direct-Line Console (DLC), on which multiple incoming calls can ring
simultaneously, the QCC receives one call at a time. regardless of the number
of calls in the QCC queue. When a call rings on a Call button, call origin
information is shown on the display.
For Release 4.0 and later releases, if Voice Announce for QCCs is Enabled, then
the fifth Call button can be used to announce a call on another user's
speakerphone if there is available a Voice Announce capable SA button at the
receiving telephone. If Voice Announce is Disabled (factory setting), then the
fifth Call button functions the same as any other Call button. Inspecting this
