Greetings.
My organization has been using Cisco Meeting Server (CMS) for a couple years now and have really put it to good use. As most customers of this product know, there is no built-in capability in CMS or in Meeting Management (MM) for historical reporting on Call Detail Records (CDR). I looked into the most popular solution on the market and found it to be too expensive and complex.
So I wrote my own, and it took a couple months.
It's a simple two-tier application that uses a MSSQL database and IIS. I wrote and deployed it using Visual Studio. I published it on GitHub at https://github.com/leeburleson/CMS-CDR and welcome all improvements and constructive criticism.
For convenience, I'm attaching the System Guide here, but everything else will be on Github.
Disclaimer: I am not a professional developer by trade and have never used Github until now. There is obviously no official support for this app, but I will answer questions as best as I can, given my experience in the field.
