Hi,
Thanks for the answer. I've only downloaded the windows installer. From your
comments it looks like you're suggesting I recompile to decode the
sub-system numbers I'm interested in. It seems strange to me... when does
SCCP carry anything other than TCAP? Never as far as I know (I'm sure other
will correct my if I'm wrong)
I now have two questions: what do I need to compile ethereal on windows? (I
have cygwin, will that help?) ... and would it be possible for there to be
some kind of setting in the GIU to decide what SSNs to handle in TCAP.
I've just thought of a third question which may help me more: Is there a way
to change the SSNs in the trace file to ones that will trigger the TCAP
decoder?
Sorry I only have questions, I'm new to ethereal, but maybe one day I'll be
able to contribute something back ...
/John.

Hi,
the TCAP decoder currently registers for the following SSNs:
dissector_add("sccp.ssn", 5, tcap_handle); /* MAP*/
dissector_add("sccp.ssn", 6, tcap_handle); /* HLR*/
dissector_add("sccp.ssn", 7, tcap_handle); /* VLR */
dissector_add("sccp.ssn", 8, tcap_handle); /* MSC */
dissector_add("sccp.ssn", 9, tcap_handle); /* EIR */
dissector_add("sccp.ssn", 10, tcap_handle); /* EIR */
dissector_add("sccp.ssn", 11, tcap_handle); /* SMS/MC */
dissector_add("sccp.ssn", 12, tcap_handle); /* IS41 OTAF */
Since INAP is not listed here, it is not supported. Someone
has to provide an INAP dissector.
Best regards
Michael
