Hi, 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).
The message on the right has no SSNs in the SCCP Called/Calling addresses. Wireshark uses the SSN to know that the message is TCAP (as opposed to some other upper-layer protocol). I suppose that if this is really a problem SCCP could have a preference for a "default" upper layer protocol if none is found via SSNs. ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
