An Overview of the 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 (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.
Reducing Power Consumption on the Phones
The Cisco Unified IP Phones support Cisco EnergyWise (EW). 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
is powered with switch's Power over Ethernet (PoE) port instead of the power adapter.
You set up each phone to enable or disable the EnergyWise settings
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.
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, see
System Configuration Overview
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:
