Hi, It looks like Wireshark has some problems decoding TCAP/MAP payloads of SCCP UDTs when there is no SSN in the CgPA, CdPA...
What I have tried... 1. "Decode as..."; however, for SCCP payloads this works only on some specific SSN. And SSN is not present in the CgPA, CdPA... 2. Preferences/Protocols/SCCP/User Table; again SSN is explicitly required. Is it possible to configure it _without_ an explicit SSN (based on the PC, NI aso?) 3. Preferences/Protocols/SCCP/Default Payload: TCAP. This one works for _most_ of the TCAP/MAP payloads. However there are SCCP UDTs for which Wireshark is decoding only the TCAP information (i.e. Continue, End, the tids aso) but it cannot decode the MAP component. Any idea why? Version information: Version 4.6.2. on Linux/Ubuntu 22.04 Thanks a lot, Cristian
