Hi,
Hopfully thinking before replying this time, I agree with Guy Harris
"Instead, what should probably be done is:
have a "dissect_cause_ie()" routine that takes a tvbuff_t *, an
offset, a length, a proto_tree *, *and* a const value_string *
as arguments - it's code would be what's in
"dissect_q931_cause_ie()", except that it uses the specified
value_string table to dissect the cause code;
the Q.931 dissector should call it with the current cause code
value_string table, which should not be modified;
the ISUP dissector should call it with a new Q.850 cause code
value_string table."
Sorry for any inconvinience caused.
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.
