[OpenSER-Users] CDRTool --Suggestion Required

Hello users, Actually i want to implement prepaid billing solution to my customers using radius accounting I have gone through the documentation provided with the sources of CDRTool and got confused with all dsn details,connections to mediaproxy ,asterisk,radius,openser. I want to first understand the call flow if using this CDRTool so that i can design mysetup. The present setup i have is 1)openser for authentication 2)Call control using asterisk+asterisk-b2bua in combination with radius Then u may ask why i am after this CDRTool because i was unable to deduct the balance and implement different tariffs using that setup in realtime so i wish to know from you what are different setups i can made using the jumbo CDRTool project so that i can select one and working . First give me suggestion so that i will start with minimal setup -- Srinivas Antarvedi
