[SR-Users] Get duration in cnxcc:call-shutdown event

Hello, Is there a straight forward way of getting the duration of the call in cnxcc-call-shutdown event. The $DLG_lifetime returns NULL as the dialog does not exist. I dont get the value of $DLG_lifetime even in dialog:end event when the call ends through cnxcc module. Even the cdr flag of acc module doesn't get the duration and it logs, invalid values !! Currently, I am storing the timestamp in htable when the call is answered and then subtract it from the current timestamp in the cnxcc:shutdown event route to get the duration. Something like this: onreply_route[MANAGE_REPLY] { xdbg("incoming reply\n"); if(status=="200") { $sht(ts=>$ci) = $Ts; } } event_route[cnxcc:call-shutdown] { $var(duration) = $TS-$sht(ts=>$ci); sht_rm_name_re("ts=>$ci"); xlog("L_INFO", "Duration of call was $var(duration)"); } Any more correct way of doing this would be very helpful. Thanks, --- Jayesh
