Features
Barge In
n Description
Barge In permits an extension user to break into another extension user's established call, including
Conference calls. This sets up a Conference-type conversation between the intruding extension and the
parties on the initial call. With Barge In, an extension user can get a message through to a busy
co-worker right away.
There are two Barge In modes: Monitor Mode (Silent Monitor) and Speech Mode. With Monitor Mode,
the caller Barging In can listen to another user's conversation but cannot participate. With Speech
Mode, the caller Barging In can listen and join another user's conversation.
CAUTION
The use of monitoring, recording, or listening devices to eavesdrop, monitor,
retrieve, or record telephone conversation or other sound activities, may be illegal
in certain circumstances. Legal advice should be sought prior to implementing any
practice that monitors or records any telephone conversation. Some form of
notification to all parties to a telephone conversation may be required, such as
using a beep tone or other notification methods or requiring the consent of all
parties to the telephone conversation, prior to monitoring or recording the
telephone conversation.
