Feature Reference
QCC Hold Return. Determines what happens to a call that a QCC
operator has put on hold and that has not been picked up after the
operator hold timer has expired twice. (The timer is not counted as
having expired until the operator actually hears the reminder.) The QCC
Hold Return option applies only to QCC operators. This option can be set
to the following values:
Remain on Hold (factory setting). The call remains on hold until
picked up. The QCC operator continues to hear an abbreviated ring
every time the operator hold timer expires.
Return to Queue. The call returns to the QCC queue. The caller hears
ringback.
QCC Hold Release. Determines what happens when a QCC operator is
on a call and presses another Call button. The Hold Release option
applies only to QCC operators. This option (equivalent to DLC Operator
Automatic Hold for DLC operators) can be set to the following values:
Automatic Hold. The active call is put on hold. This prevents
accidental disconnection of callers.
Automatic Release (factory setting). The active call is released. This
allows the operator to disconnect one call and answer another by
pressing a single button.
Considerations and Constraints
The factory setting for the hold disconnect interval is Long (450 ms), since that
is the interval used by most local telephone companies.
If the hold disconnect interval set for the system does not match that of the local
telephone company, the system may have the following problems with calls on
hold:
If the interval is shorter than the setting at the local central office, callers
on hold may be disconnected.
If the interval is longer than the setting at the central office, the LED next
to the line button continues to flash after a caller on hold hangs up.
Both parties on an inside call cannot put each other on hold. If a user presses
the Hold button while waiting on hold on an inside call, the call is disconnected.
Telephone Differences
Direct-Line Consoles
When DLC Operator Automatic Hold is enabled, a DLC operator can put an
active call on hold by pressing another line button or DSS button.
