Direct-Line Consoles

If the 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 use 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 set users can
use Barge-In to call or monitor single-line telephones.
Feature Interactions
Basic Rate Interface
Callback
Conference
Coverage
Digital Data Calls
Barge-In can be used for a voice call 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 queued 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 trunk and the person on the outside 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.
