Microsoft Senior Support engineers walk you through real-life support cases, giving you an insider’s view into the systematic approach they use to troubleshoot Lync Server issues.
These short videos focus on specific tasks and show you how to accomplish them for Microsoft Lync Server 2010.
The Lync PreCall Diagnostic Tool (PCD) is a client-based application that allows you to see how the current state of your network might impact the audio quality in an upcoming Enterprise Voice call. The PCD tool was originally released for Office Communications Server 2007. This is a new version of the tool designed specifically for Windows 8.
PCD is most useful in situations where the last hop of a network is likely to be the weakest (for example, with laptops on a public WiFi network or home users). PCD creates a small packet stream that traverses this final leg of the network. The tool then analyzes the packet stream to estimate how the jitter and loss along this leg might impact call quality, and then provides a report. You can run PCD continuously on the client, even while calls are being placed. The packet stream does not have a significant effect on bandwidth.
