Troubleshooting Cisco UE System Features

This chapter covers the following topics:

• General Cisco Unity Express (UE) system troubleshooting techniques
• Troubleshooting problems that might occur during system installation
• Troubleshooting Cisco UE startup problems
• Troubleshooting the Cisco UE Initialization Wizard
• Troubleshooting the system backup and restore operations

The previous chapters in Part IV, "Maintenance and Troubleshooting," took a closer look at Cisco CallManager Express (CME) troubleshooting of the call processing and phone components of your system, as well as some voice mail scenarios with external voice mail systems such as Cisco Unity. This chapter takes an in-depth view of troubleshooting Cisco CME's integrated voice mail application, Cisco Unity Express (UE).

Cisco UE's hardware and software architecture was discussed in Chapter 3, "Cisco IPC Express Architecture Overview." This fundamental architectural knowledge is required to understand the troubleshooting tools and techniques discussed in this chapter. In Chapter 3, you learned how a Cisco IOS router interfaces with the Cisco UE hardware module using the Router Blade Communication Protocol (RBCP), which is the fundamental mechanism used as the communication path between Cisco UE and the Cisco CME router and is integral to understanding later sections in this chapter.

This chapter covers troubleshooting the system-level aspects of Cisco UE, such as general problem isolation techniques, installation, startup, and backup and restore.
