Hi,
ANSI MAP doesn't decode ReturnResult Action code.
It is starnge description here:
Dissector for ANSI TCAP NATIONAL code:0
I've checked specification "TCAP ANSI T1.114 2000", and understand that
terminology "National TCAP" or "Private TCAP" is applied for "Operation Code"
only.
You can see "Private TCAP" flag for first message "Analyzed Information Request
Invoke" in attached pcap log.
But for TCAP.ReturnResult parameter "operation code" don't exist at all.
So it is not possible to understand by ReturnResult if it is "Private TCAP" or
"National TCAP".
Because Invoke and ReturnResult encoded the same TCAP,
it is just possible analyze origination invoke and understand which TCAP was
used "National" or "Private" for both messages.
So I suppose that I attached correct ANSI MAP (WIN) communication, both
messages are used "Private TCAP". But second message parameter Wireshark
doesn't decode.
In attachment:
output.rec.pcap - two messages ANSI MAP
1. Analyzed Information Request Invoke
2. ReturnResult (Last) response

Best wishes,
Igor Lobiv
