[Freeswitch-users] Memory leak in mod_nibblebill or in ODBC core?

I didn't try yesterday Anthony's update, but his previous fix works OK.

Please note that comments in nibblebill config file and default actions in

incorrect, the parameters are not the applications to execute, but dialplan 
extensions to transfer the call to.
