Hi,
it seems that it was implemented by me (rev 17530, March 2006) but I do not remember why.
I will fix it.
Tomas

Hi,
After reading your previous post on the subject I did a quick check
Of the ITU spec and it looks like you are right...I'm not sure why the
Check is there - Tomas? Ronny?

Ämne: [Wireshark-dev] ASN.1 enumeration extension coding question
Hi,
Is this the proper forum to ask a question about 'why' something is
coded the way it is?
We are developing a V.34 enabled T.38 end point, and are confused by the
Wireshark decoding. It seems the Wireshark decoder is aligning fields
which are extension values. For example, the 2002 T.38 ASN.1 notation
for V.34 Data Field values. We are not aligning these enumeration
values, but Wireshark does. See line 1211 of packet-per.c, a comment
which says to align without giving a reference, and 1214 which does the
alignment. Reading ITU X.691 section 13, I would not expect this
beahvior. As Wireshark community is the only place I know of an
existing product which handles the V.34 additions to T.38, it seems a
good place to ask. Why are these values aligned? We could not find an
ITU reference giving us reason to do so.
Thanks,
