Wireshark · Ethereal-dev: SV: [Ethereal-dev] Changed cause code "strings " in packet-q931to conform to q.850

["Anders Broman" <a.broman@xxxxxxxxx>]

Hi,
Well there is actually three issues :
1) Is Q.850 actually defining CAUSE both for ISUP and Q.931 ?
2) Is the Cause code strings correct in Q.931 dissector ?
3) ISUP dissector does not translate cause code to string, it only referes
to Q.850.

I was hoping to fix the two later by changing the cause code strings in
q.931 dissector then call that
dissector from the ISUP disector.

But of cource I could try and "copy" the Cause code part from q.931
dissector into the ISUP dissector and
use Q.850 cause codes there.

Best regards
Anders

I have them on my (FreeBSD) desktop (at home) - in fact, I could have
had *two* copies of the Q.850 spec just now, because I'm an idiot and
bought a copy from the ITU Web site before checking whether I already
had one - and it looks as if at least some of the problematic cause
codes aren't specified in Q.931.

However, some pages seem to show those cause codes, e.g.:

	http://www.planet.net.au/~neale/aus-isdn/Q931short.html

"008 Prefix 0 dialed but not allowed".

I don't know whether that's because they're national ISDN codes rather
than Q.931 standard codes, or what.
