Describe How to Provide End-User Support for
Connectivity and Voice Quality Issues
Troubleshooting a complex application like CUCM can be challenging. The scope of
CCNA Voice (ICOMM) requires us to keep it relatively simple, so the following sections
should by no means be considered a comprehensive CUCM troubleshooting manual. In
this chapter, you learn how to troubleshoot basic IP Phone registration issues and look at
the extensive reporting capabilities of the CUCM system, which helps you monitor the
health and well-being of the servers in your deployment.
Note that the following section on troubleshooting methodology is duplicated in Chapter
9, “Managing Endpoints and End Users with CME.” It appears again here because it is im-
portant, and it makes it easier to refer to as you read this chapter.
Troubleshooting
When troubleshooting, employing a consistent and systematic methodology saves time
and helps prevent errors from making the situation worse. The sequence of steps de-
scribed here is supported by Cisco best practices as one model for effective troubleshoot-
ing. Figure 16-1 illustrates the troubleshooting sequence.
