Features
Barge-In
Telephone Differences
Direct-Line Consoles
If a DLC operator uses Barge-In to reach someone with Coverage or Forwarding
(including Remote Call Forwarding) on, the call from the operator is not directed to
the destination (receiver's) extension. The call is directed to the extension on
which Barge-In is used.
Queued Call Consoles
A QCC operator can use Barge-In only by selecting the feature from the display.
Barge-In can be used to join an inside call to a QCC operator only if the user dials
the caller's extension instead of the QCC operator's number. If a user tries to
activate Barge-In after dialing a QCC system operator's extension and waiting in
the QCC queue, the feature has no effect and the user hears an error tone. If the
error tone times out while the call is still in the QCC queue, the call is
disconnected. However, if a QCC system operator becomes available before the
error tone times out, the error tone is removed and the call is delivered to the
operator normally.
Single-Line Telephones
Single-line telephones cannot use Barge-In, but other telephone users can use
Barge-In to interrupt or monitor calls on single-line telephones.
Feature Interactions
Basic Rate Interface
Callback
Conference
Coverage
Digital Data Calls
Direct Station
Selector
Barge-In can be used for a voice calls on a BRI line, but not on BRI data
calls.
If Callback is used to request a busy extension or pool and the user is
waiting on the line for the callback call, Barge-In cannot interrupt.
Barge-In can interrupt conference calls; all participants hear the Barge-In
tone. Barge-In does not connect the user to a conference call if the
conference already has the maximum number of participants. If Barge-In
is used to connect to a conference call that involves an outside line/trunk
and the person on the outside line/trunk hangs up, the person using
Barge-In is also dropped.
Barge-In can be used for Individual or Group Coverage calls answered at
any receiver's extension. However, if an operator uses Barge-In to reach
an extension with Coverage, the call from the operator is not directed to
the receiver's extension.
Data calls cannot be barged into.
After making a call to an extension by using a DSS button on a DLC,
activate Barge-In by pressing a programmed Barge-In button. QCC
operators select the feature from the display.
