Heading off Potential Problems with Enterprise Voice
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
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 Viewer to help identify potential issues; you can use Monitoring Server to monitor trends and identify issues before they have a significant impact on users; and you can use the Deployment Validation Tool to 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 Events and Appendix B: Enterprise Voice-Related Performance Counters.
