Calling Group Options
This section describes the Group Calling options assigned through system
programming and available only for calling groups.
Queue Control
In Release 6.0 and later systems, the system manager can control the maximum
number of calls allowed in the primary calling group queue (not an overflow
queue) for calls that arrive on certain facilities often assigned to calling groups.
The factory setting is 99, but any value from 0 to 99 can be specified as the
maximum. When the number of calls in queue reaches the programmed
maximum, subsequent eligible callers receive a busy signal.
Queue control applies to the following types of calls:
DID and dial-in tie trunk calls
PRI facilities programmed for dial-plan routing
Calls that are transferred from a VMI port
Calls transferred on an inside or private network line
Inside calls to the calling group
Inside Dial 0 (#0) and #800 calls delivered to the calling group that is
assigned as the QCC Position-Busy backup
NOTE:
For private network trunks, the call returns only when PRI lines are
used and the transfer has been manually completed. Calls
transferred to a local calling group or using network PRI lines return
to the transfer originator.
