Hi Alex, This is the generic nack that an entity may send if there was a problem with a previously sent PDU.
Header: 80 00 00 00 Command Status: 00 00 00 03 (Invalid command ID) Sequence Number: 00 00 02 4e (Sequence number of previously sent PDU) The SMSC appears not to have understood the type of PDU with sequence number 24e. If you look at your log and check the PDU that Kannel sent with sequence number 24e then this will be the PDU that the SMSC did not understand. I would suggest that you check with the SMSC operator to see whether there SMSC supports that particular PDU. Kindest Regards, Michael Mulcahy.
