[OpenSIPS-Users] Sending CDR over event_datagram module

[Răzvan Crainea]

Hi, Dan!

Yes, you are on the right path. You do have to specify the evi_flag, 
otherwise the acc module does not know what kind of accounting to do (DB 
based, log based, aaa based, events based). If you don't specify the 
cdr_flag, then you will get an old-style accounting - for a single call 
you will get two events, one for INVITE and one for BYE. To compute the 
duration you have to make the difference between their timestamps. When 
using the cdr_flag, OpenSIPS raises only a single event, that contains 
all the call details, including the duration.
If you set the evi_flag on BYE messages too, do you receive two 
E_ACC_CDR events, or one E_ACC_CDR and one E_ACC_EVENT?
