Overview of Configuring and Installing Cisco Unified IP Phones

Security Restrictions
A user cannot barge into an encrypted call if the phone that is used to barge is not configured for
encryption. When barge fails in this case, a reorder tone (fast busy tone) plays on the phone on which
the user initiated the barge.
If the initiator phone is configured for encryption, the barge initiator can barge into an authenticated or
nonsecure call from the encrypted phone. After the barge occurs, Cisco Unified Communications
Manager classifies the call as nonsecure.
If the initiator phone is configured for encryption, the barge initiator can barge into an encrypted call,
and the phone indicates that the call is encrypted.
A user can barge into an authenticated call, even if the phone that is used to barge is nonsecure. The
authentication icon continues to appear on the authenticated devices in the call, even if the initiator
phone does not support security.
