Description
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, the user presses the Feature button
and selects
A tone, heard by the user and the people on the call, indicates that the user is
bridged onto a conversation in progress. Ringing indicates that Do Not Disturb
is on at the extension.
Considerations and Constraints
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.
