• Barge-In works only if the user about to be barged in is in a two-way normal speech with another user
or external party.
• It will not work if the busy signal is due to the user being OFF-Hook, or in the middle of dialing, or
accessing a feature of the PBX.

Toggle feature.
• Privacy against Barge-In: If the feature 'Privacy against Barge-in is enabled for an extension, it cannot be
barged into.

How to configure
The functioning of this feature is controlled by three parameters, 'Barge-In', 'Privacy against Barge-In' and 'Barge-In
Timer'.
Barge-In and Privacy against Barge-In
First decide which of the extensions are to be allowed Barge-In and the extension that are to be protected against
Barge-In.
By default, all extension port types have Barge-In and Privacy from Barge-In disabled in their Class of Service.
While it makes sense to offer all extensions Barge-In, providing Privacy from Barge-In also to all extensions will not
serve the purpose of Barge-In.
Decide which extensions are to be allowed 'Barge-In', and which are to be allowed 'Privacy from Barge-In' and
enable these features in their Class of Service for the Day and Night.
Refer the topic “Class of Service (COS)” for instructions.
Barge-In Timer
Barge-In Timer is the time after which the caller gets connected to the called party. By default the Timer is set to 10
seconds. To configure the Barge-In Timer, see Other Features under “System Timers and Counts”.
