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 (fast
busy) tone plays on the phone of the barge initiator.
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.
