I am working Kamailio (4.0.1) server with GUI package Siremis (4.0) of it. I was successful in get through Calls and SMS features in our VoIP phones using this kamailio sever. And now i am trying to get GUI for my kamailio server with SIREMIS (4.0.0) package. Installation was good as i am getting subscribers list in GUI which are in MySQL database. As it comes accounting section. i am Failed to get the  CDR list when the call session between two clients have been done. I gone through Acc module's documentation and followed the following links to set up the accounting in GUI :

http://kb.asipto.com/siremis:install40x:accounting.

And i read this is description in accounting module documentation :
'Note that CDR generation does not involve any kind of database storage (yet). In order to persist the CDRs into a database you will have to set up an exterior process (i.e., a script living outside of Kamailio) and implement the storage task yourself'.
So what does it mean ? should i have to install external process like CDR tool and Freeradius?
