Malformed packet in the GSM MAP
Hi,
We couldn't decode some GSM MAP packets in the wireshark.
Kindly check and revert, how to decode it properly in the wireshark.
Thanks, Varghese

This GSM SMS message really seems to be malformed. It's header indicates that the TP-User-Data-Header is present. So the TP-User-Data 20 58 0E 86 c3 01 starts with a User Data Header. Per 3GPP 23.040 chapter 9.2.3.24, the first byte (here 0x20) is the length of the header. But there are only 5 bytes remaining in the payload and not 32, thus the decoding failure. What was the expected content of the SMS message?

At the very least you would need to provide the capture that has the issue and your OS and Wireshark version details.
Thanks for the response. I couldn't attach the trace here, So I just pasted below and Version 1.2.8 (SVN Rev 32676)
[... snipped for brevity ...]
(more)1.2.8 is a very old version (nearly a decade), any chance of trying a modern one that might have fixed the issue?
