Overview

A simple or concatenated message has failed to be delivered to the recipient, with a TC-ABORT apparently being received from the Lithium FW. However, other SMSFW logs indicate that the message did get through, with a Pass message.

Information

A known explanation for the reported problem is that the TC_Abort message is being received from the SMSC side, rather than the firewall. In the following example, extracted from a message trace, we can see that the TC-ABORT was received from 56789, while the FW 1234 is sending a TC-CONTINUE message:
