CDR-like logs

Hi. If I enable detailed-enough logs of OpenBSC I can get data regarding call and sms transactions: new state INITIATED -> MO_CALL_PROC, 1 active transactions new state MO_CALL_PROC -> CONNECT_IND, 1 active transactions new state CONNECT_IND -> ACTIVE, 1 active transactions new state ACTIVE -> DISCONNECT_IND, 1 active transactions new state DISCONNECT_IND -> RELEASE_REQ, 1 active transactions new state RELEASE_REQ -> NULL, 0 active transactions However there's no information regarding which mobile is participating in the transaction. Is there some way to get CDR-like data from OpenBSC? Smth like imsi=123 call_to 35345345 duration 12 imsi=53 sms_from 234234 ... cheers, Max.
