Hi Yuriy, As a disclaimer, I am one of the developers of CGRateS, so you can take my opinion about how alive the project is as subjective ;). You can find some "facts" about the liveness of the project from a more neutral entity by ohloh.net here: http://www.ohloh.net/p/cgrates Let me know if any particular questions arise (or if any issues found with the software). Thanks, DanB
