The privacy feature
enables phone users to block other users who share a directory number from
seeing call information, resuming a call, or barging into a call on the shared
line. When a phone receives an incoming call on a shared line, the user can
make the call private by pressing the Privacy feature button, which toggles
between on and off to allow the user to alter the privacy setting on their
phone. The privacy state is applied to all new calls and current calls owned by
the phone user.
Privacy is supported
on SCCP octo-line directory numbers and SIP shared-line directory numbers.
Privacy is enabled
for all phones in the system by default. You can disable privacy globally and
enable it only for specific phones, either individually or through an phone
template. You can also enable the privacy button on specific phones. After a
phone with the privacy button enabled registers with Cisco Unified CME, the
line feature button on the phone gets labeled “Privacy,” a status icon
displays, and if the button has a monitor lamp, it lights when privacy is
active. For Extension Mobility phones, you can enable the privacy button in the
user profile and logout profile.
The Privacy on Hold
feature prevents other phone users from viewing call information or retrieving
a call put on hold by another phone sharing the directory number. Privacy on
Hold is disabled for all phones in the system by default. You can enable
Privacy on Hold globally for all phones. To disable Privacy on Hold on
individual phones, you must disable Privacy on those phones.
The Privacy feature
applies to all shared lines on a phone. If a phone has multiple shared lines
and Privacy is enabled, other phones cannot view or barge into calls on any of
the shared lines.
