Iirc, the developer added support only for cdrs to log file. If nobody works on it, probably i will do it before next major release.

I understand that CDR support requires the dialog module and I figure that the dlg_flag needs to be set and cleared in the route script, but I'm not sure where.

I think this is because I need to set and clear the dialog flag at appropriate places in the route script (e.g. setflag(FLD_DLG)) but I'm not sure where. Should this be done in the INVITE and BYE method handling as is currently done for the transaction accounting, e.g.:
