Does anyone here have a proper sample of a trace of a SCCP XUDT message including segments?
My self made packet decodes correctly in wireshark but the global title 
node doesn't like it and rejects it with 0x08 (Message Transport 
Failure) and I don't have anything to compare against what could be wrong.
Here's what I sent
There's some segmented XUDT (and XUDTS) in

"Message Transport Failure" implies a message ordering problem or timeout. Looking at your MTP routing label the 2 messages are on different SLS despite the fact that Class-1 is selected. That might be the problem. (I didn't check a lot for other possible problems.)
