Purpose

The Troubleshooting Guide for Cisco CallManager provides descriptions of the tools and utilities used to configure, monitor, and troubleshoot Cisco CallManager Release 3.1(1), Cisco IOS Gateways, and Gatekeeper.

Appendices provide detailed examples of three different call flows. In the first case study, a Cisco IP Phone calls another Cisco IP Phone within a cluster, which is called an intra-cluster call. Once you understand the call flow and debug traces, it will be easier to isolate a problem and determine which component is causing the problem.

Audience

The Troubleshooting Guide for Cisco CallManager is written for network administrators responsible for managing the Cisco CallManager system, enterprise managers, and employees. This guide requires knowledge of telephony and IP networking technology.
