Hi list, I have information, which maybe usefull for you.
Currently SMPP DLR checks deliver_sm PDU's short_message field for value like: "id:IIIIIIIIII sub:SSS dlvrd:DDD submit date:YYMMDDhhmm done date:YYMMDDhhmm stat:DDDDDDD err:E Text: . . . . . . . . . " That was not suitable for me, because my smsc provider doesn't send anything in short_message field. Instead, they have optional fields (described in SMPP 3.4 spec): receipted_message_id (C-octsrt, 65) , message_state (int, 1). receipted_message_id is the same as deliver_sm_resp.message_id and it is unique value (contains timestamp, date, .....). I was forced to add some fields to deliver_sm definition and make some changes in smsc_smpp.c (they are not very clean, but at least I can get DLR). Also here was talks about different formats of message_id, in my case its always C-octstr (as in SMPP 3.4 spec). If you would like to add new mechanism of SMPP DLR based on message_state and receipted_message_id, I can contribute. Best Regards, -- David Chkhartishvili
