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.
You can use Snooper.exe tool to view SIP and Conferencing Control Channel Protocol (CCCP) logs that are generated by Office Communications Server. Snooper loads the supplied log file and displays the messages that it contains. You can also use Snooper to view failed voice call reports (database reports).
To use Snooper from within Logging Tool or as a stand-alone tool, you must install the Microsoft Office Communications Server 2007 R2 Resource Kit Tools, available as a free download at the Microsoft Download Center at https://go.microsoft.com/fwlink/?LinkID=145159. The Resource Kit Tools Readme includes documentation for the tool.
