Cisco 7941G Administration Guide

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.
Phone Power Consumption
The Cisco Unified IP Phone 7900 Series supports Cisco EnergyWise. EnergyWise is also known as Power
Save Plus. When your network contains an EnergyWise controller, you can configure these phones to sleep
(power down) and wake (power up) on a schedule to reduce your power consumption. The phone should be
powered by the Power Over Ethernet (PoE) port of the switch instead of the power adapter.
You set up each phone to enable or disable the EnergyWise settings. You can also configure EnergyWise
parameters on the enterprise and common phone configuration. If EnergyWise is enabled, you configure a
sleep and wake time, as well as other parameters. These parameters are sent to the phone as part of the phone
configuration XML file.
The switch administrator can wake the phone up before the scheduled time. For more information on powering
up the phones from the switch, see the switch documentation.
Cisco Unified IP Phone Deployment
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, see 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 Cisco Unified IP Phones to the system.
The following topics provide an overview of procedures for adding Cisco Unified IP Phones to your network.
Cisco Unified IP Phones Setup in Cisco Unified Communications Manager
To add phones to the Cisco Unified Communications Manager database, you can use:
•
Autoregistration
•
Cisco Unified Communications Manager Administration
•
Bulk Administration Tool (BAT)
•
BAT and the Tool for Auto-Registered Phones Support (TAPS)
For general information about configuring phones in Cisco Unified Communications Manager, see the
“Cisco Unified IP Phones” chapter in Cisco Unified Communications Manager System Guide.
