I currently have wireshark 1.2.9 and I’m not able to
decode M3UA traffic exchanged between SMSC and STP. Decoding ends up on
ETH/IP/SCTP/M3UA/SCCP layer and the rest is non decoded raw data.
Could anyone tell me what’s wrong in the traffic?
Please see HTML output bellow (left side correctly decoded, right side
incorrectly).
