Kannel does comparison for the SMSC-ID(Kannel) and the supposedly unique Timestamp(the message ID generated by the SMSC ). The SMSC-ID+Timestamp should obviously make a unique combination.
See dlr_find (and dlr_find_mem) method in dlr.c for understanding how this works. What kannel does is adds this id first time it gets a submit_sm_resp to dlr table ( internal, mysql or any other) and then compare it with deliver_sm's id field. -Tarun -- http://www.tarundua.net Nothing you ever wanted to find about Tarun Dua
