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 CallManager 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 CallManager System Guide.

After you have set up the IP telephony system and configured system-wide features in Cisco Unified CallManager, 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 CallManager, page 1-22

•Installing Cisco Unified IP Phones, page 1-26
