MONITOR PRIVILEGE CONTROL

In order to restrict ability for any extension to use barge feature and spy on any ongoing call, UCM6xxx
series introduced "Monitor Privilege Control" option, starting from firmware 1.0.12.x, allowing to select
specific extensions allowed to barge into a call.
For example, in extension 1000's settings, select 1002 from Available Extensions to Selected
Extensions on the right. When 1000 is in active call, only extension 1002 can barge in.
This feature can be configured from UCM6xxx Web GUI  Extensions / Trunks  Create or Edit
Extension  Features  Monitor privilege control.
