Subject: ANSI MAP / TCAP dissector hooks
Hello,
why was the way ANSI MAP hooks into TCAP changed?
I believe there is a problem with it.
I have attached a capture file with the following:
SCTP
M2UA
MTP3 (ITU)
SCCP
TCAP (ANSI)
ANSI MAP
My preferences were set to:
MTP3 (ANSI)
ANSI MAP (SSN RANGE 5-14)
Procedure:
1. Start Ethereal
2. Set filters
3. Load file
Frames show up as SCCP (ANSI), ERR and DT2
4. Edit preferences, change MTP3 -> ITU
With Ethereal 0.99.0 everything works fine the four frames come out decoded
as ANSI MAP
with:
UDT QueryWithPermInvoke(Last) Location Request UDT QueryWithPermInvoke(Last)
Routing Request UDT ResponseRetRes(Last) UDT ResponseRetRes(Last)
Following the same procedure with Wireshark 0.99.2 the decode goes as far as
TCAP but not ANSI MAP.
To get the decode to work properly I have to:
5. Edit preferences, change ANSI MAP SSN Range to something different,
apply
