Cisco TVOICE 8.0: Cisco Unified Communications Manager Troubleshooting

This course is included in our On-demand training solution.

Overview

After you migrate your voice network to include Cisco Unified Communications Manager functionality, the entire structure of your voice network changes. Nearly all devices should now communicate across the data network structure, keeping the number of analog devices used at a minimum. Because the PBX functionality has been replaced with the Cisco Unified Communications Manager cluster, much of your troubleshooting focus now changes to include the Cisco Unified Communications Manager system.
The Cisco Unified Communications Manager is an appliance that is based on Linux and uses IBM Informix as the database for configuration, historical data, and all user information. This course will cover issues that are related to these areas: Cisco Unified Communications Manager availability, database replication issues, Lightweight Directory Access Protocol (LDAP) issues, endpoint registration issues, and gateway registration issues.

Target Audience
