Built-in CDR Analysis and Reporting tool is nice, but I need to keep CDR files for more than several months.
Do you know about any freeeware programs running on Windows, which will grap CDR files and dump them into SQL server and then use some sort of web access to make queries.
I don't need to run any reports, but it would be nice to have such option.
The main concern - it has to be free of charge
Thanks for you answers!
I haven't investigated any freeware programs that do this, but be sure any application you investigate does NOT install anything on your CUCM servers. If you change your mind on considering a purchased solution, I really like the Avotus call accounting application and have personal experience with its predecessor, MDR SwitchView with CallManager. This is one of those products that exemplify "you get what you pay for". Since I'm throwing my opinion in here, you may also want to consider an application that captures your CUCM CMR traffic data. It can be very useful to gather statistics on:
Have you tried http://www.cdr-stats.org
it's completely free and open source.
They say they support Cisco out of the box. It runs on a linux machine, I haven't installed it as I couldn't find any guide on how to make it work with CUCM, I'm no Linux expert.
But the graphs and charts seem like the best I've seen, better than all the paid software out there!
Another good option is VoIP Detective. There is both a free and a paid version, and it does a great job parsing Cisco CDRs and CMRs. You can get it at www.VoIPDetective.com
