In addition to troubleshooting specific issues as described in this document, early detection can significantly decrease the number of user issues that you encounter. For example, you can regularly monitor Event Viewerto help identify potential issues; you can use Monitoring Serverto monitor trends and identify issues before they have a significant impact on users; and you can use the Deployment Validation Toolto generate simulated audio traffic through your Office Communications Server deployment to detect quality and connectivity issues. For details about tools that are available for use with Office Communications Server, see Troubleshooting Tools for Enterprise Voice.

In addition, Office Communications Server performance counters can indicate configuration issues that can affect Enterprise Voice calls. You should monitor performance counters and corresponding event records to determine any failures that are related to specific counters, and then determine whether troubleshooting is required. For details, see Appendix A: Enterprise Voice-Related Eventsand Appendix B: Enterprise Voice-Related Performance Counters.
