If you don’t have direct access to the machine, it may be necessary to capture using command-line tools like tcpdump. ResolutionĬapturing network traffic without Wireshark If you are using an SMPP simulator instead of connecting to a real SMS-C, you should use the source code (or a debugger) to understand what is happening. If the SMS-C replies with an error, your SMS-C partner will be the best person to tell you why it replied with the error. When troubleshooting problems, always contact the SMS-C partner to obtain information or to help you double-check what you get. Since the SMPP protocol contains many different parts left to the interpretation of the implementation team, there are differences between different SMS-C. This article is not a substitute for this specification: it gives practical tips on how to interpret the protocol specification and match it with the Wireshark display in order to help troubleshoot problems between Adobe Campaign and the SMS-C partner. The SMPP protocol is documented in the SMPP Protocol Specification v3.4 available on the internet as a PDF document. This protocol allows sending SMS and receiving information about the delivery of these SMS. Most high-throughput SMS-C are compatible with the SMPP protocol version 3.4.
