Overview of Configuring and Installing Cisco Unified IP Phones
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 Cisco Unified IP Phones to your
network:
• Configuring Cisco Unified IP Phones in Cisco Unified Communications Manager, page 1-9
• Installing Cisco Unified IP Phones, page 1-12
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)
For more information about these choices, see the “Adding Phones to the Cisco Unified Communications
Manager Database” section on page 2-7.
Ta b l e 1-3 Overview of Security Features
Feature Description
Image authentication Signed binary files (with the extension .sbn) prevent tampering with the firmware image
before it is loaded on a phone. Tampering with the image causes a phone to fail the
authentication process and reject the new image.
Encrypted configuration files Lets you ensure the privacy of phone configuration files.
Phone hardening Additional security options, which you control from Cisco Unified Communications
Manager Administration:
• Disabling PC port
• Disabling Gratuitous ARP
• Disabling PC Voice VLAN access
• Disabling access to the Setting menus, or providing restricted access that allows
access to the User Preferences menu and saving volume changes only
Note You can view current settings for the PC Port Disabled, GARP Enabled, and Voice
VLAN enabled options by looking at the phone’s Network Configuration menu.
For more information, see the
“Displaying a Configuration Menu” section on
page 4-2.
