Information

intShuttingDown means the application session was shutting down when the SMS was received.
​
rtrNoRuleMatching means no AO rule matched the message on the RTR; therefore, the message gave an error.

For this rtrNoRuleMatching, please check the configured AO rule for this application. For example, if the application is sending to numbers that are not defined in the network or short codes, these scenarios could lead to this error.
