Overview of Configuring and Installing Cisco Unified IP Phones Chapter 1 An Overview of the Cisco Unified IP Phone - Disabled-If the switch does not support multi-domain authentication, disable the Voice VLAN and consider assigning the port to the native VLAN. See Security Configuration Menu, page 4-30 for more information. • Enter MD5 Shared Secret-If you disable 802.1X authentication or perform a factory reset on the phone, the previously configured MD5 shared secret is deleted. See 802.1X Authentication and Status, page 4-43 for more information. 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 System Configuration Overview 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 1-20 • Installing Cisco Unified IP Phones, page 1-23 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) 1-20 Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager 8.0 (SCCP and SIP) OL-21011-01
