I want to start this thread to get feedback from folks who have been using Cisco reporting server.  It is a good tool to get information on what happens on the vxml server and what the user does on application side.  I have been using several reporting tools including webview, new cuis and I have also developed several custom reporting tools on Cisco platform.
Has anybody used Cisco reporting server for large applications where there are more than 500,000 calls a day and lot of data gets written.
Has anybody had any experience with reporting server in such a environment with lot of call processing. Any experience with reporting server or any feedback on issues encountered with reporting server would be appreciated.
