a short description for sake of completion: acc module for Kamailio is
sending START and STOP events, it is up to you to mitigate in the radius
backend side and get the call duration.

On the other hand, if you want to get Called, Calling, connect_time
values from INVITE at BYE time you have to use dialog module and store
those values in dialog variables. Then send those values to radius via
extra accounting. However, you will get duplicates in START record.

If you are not bound to radius, by using acc+dialog modules, you can get
one cdr per call in database (or syslog). With a bit of c coding, this
should be possible to be extended for RADIUS. Not using RADIUS myself I
wasn't able to code it myself.

Cheers,
Daniel
