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.
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 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 Cisco Unified IP Phones to your
network:
• Configuring Cisco Unified IP Phones in Cisco Unified Communications Manager, page 1-18
• Installing Cisco Unified IP Phones, page 1-21
Configuring Cisco Unified IP Phones in Cisco Unified Communications
Manager
To add phones to the Cisco Unified Communications Manager database, you can use:
• Auto-registration
• Cisco Unified Communications Manager Administration
• Bulk Administration Tool (BAT)
• BAT and the Tool for Auto-Registered Phones Support (TAPS)
For more information about these choices, see the “Adding Phones to the Cisco
Unified Communications Manager Database” section on page 2-8.
For general information about configuring phones in Cisco Unified Communications Manager, refer to
the “Cisco
Unified IP Phone” chapter in Cisco Unified Communications Manager System Guide and to
the “Cisco Unified IP Phone Configuration” chapter in Cisco
Unified Communications Manager
Administration Guide.
