• 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 the
“802.1X Authentication and Status” section on page 4-50 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.
Overview of Configuring and Installing Cisco
Unified
IP Phones
When deploying a new IP telephony system, system administrators and network
administrators must complete several initial configuration tasks to prepare the
network for IP
telephony service. For information and a checklist for setting up
and configuring a complete Cisco Unified IP telephony network, refer to the
“System Configuration Overview” chapter in Cisco Unified Communications
Manager System Guide.
After you have set up the IP telephony system and configured system-wide
features in Cisco
Unified Communications Manager, you can add IP phones to the
system.
The following topics provide an overview of procedures for adding

Unified IP Phones to your network:
