[Kamailio-Users] OpenSER 1.3.2 + Mediaproxy 1.9.2 + Asterisk 1.4 + CDRTool with FreeRadius

Hi to all, I need to implement a simple prototype of a Voip system with OpenSER 1.3.2 + Mediaproxy (for NAT traversal) + Asterisk 1.4 (for interconnection with PSTN) + CDRTool (for accounting) on a debian 4 etch operating system. I've already configured OpenSER + Mediaproxy + Asterisk with sucess. I'm missing CDRTool. I have two questions, if some one can help me: 1º which is the CDRTool version compatible with openser 1.3.2 and mediaproxy 1.9.2. Can i use the latest (6.6.10 i supose)? 2º I've read the install file for CDRTool but it is a little confusing (maybe because i'm a newbie to all this). Can anyone show me some literature (or tutorials) to accomplish this installation? Thanks in advance to all, Nuno
