Description 3
Barge-In allows a caller to contact a co-worker in an emergency or when the caller
has been given special instructions to interrupt. If the extension is busy, Barge-In
includes the user in the call. If Do Not Disturb is activated, Barge-In overrides the
feature and makes the telephone ring.
On multiline telephones, except QCCs, the caller interrupts a call or overrides Do
Not Disturb by calling the extension number and then pressing the programmed
Barge-In button. On a QCC, an operator presses the Feature button and selects
%DUJH,Q from the display.
A tone, heard by the user and the people on the call, signals that the user has
joined a conversation in progress. Ringing indicates that Do Not Disturb is on at
the extension.
Barge-In is similar to the Service Observing feature in that both features gain
access to a call already in progress. However, the person barging in can talk to
the other parties on the call; the Service Observer can only listen in on the call and
cannot communicate with the other parties.
Considerations and Constraints 3
Barge-In does not override Privacy.
If Caller A is in the process of dialing and Caller B uses Barge-In to reach Caller A,
the touch tones generated by dialing cancel the Barge-In tone. As a result, Caller
A may not be aware that someone else is joining the call.
If a caller presses the Barge-In button while calling an MLX telephone, an extra
ring occurs on the MLX telephone. A Barge-In button can be programmed only
through centralized telephone programming.
