Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager 8.5

Chapter 1 An Overview of the Cisco Unified IP Phone
Understanding Security Features for Cisco Unified IP Phones
–
Disabled—If the switch does not support multiple 802.1X-compliant devices on the same port,
you should disable the PC Port when 802.1X authentication is enabled. See Security
Configuration Menu, page 4-30 for more information. If you do not disable this port and
subsequently attempt to attach a PC to it, the switch will deny network access to the phone and
the PC.
• Configure Voice VLAN—Because the 802.1X standard does not account for VLANs, you should
configure this setting based on the switch support.
–
Enabled—If you are using a switch that supports multi-domain authentication, you can continue
to use the voice VLAN.
–
Disabled—If the switch does not support multi-domain authentication, disable the Voice VLAN
and consider assigning the port to the native VLAN. See Security Configuration Menu,
page 4-30 for more information.
• Enter MD5 Shared Secret—If you disable 802.1X authentication or perform a factory reset on the
phone, the previously configured MD5 shared secret is deleted. See 802.1X Authentication and
Status, page 4-42 for more information.
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.
