Unify2 PowerView
I get asked fairly frequently about the native reporting on OCS R2 – now you can make life really is with this tool from Unify2
“PowerView is a comprehensive reporting and billing solution for Microsoft’s Office Communications Server (OCS). It comes with a wide range of reports, including reports that track the overall OCS deployment, optimize the OCS deployment, track the Return on Investment (ROI), and produce billing or charge-back reports based on the usage of OCS.”
