Paul,
I
still don't see why the existing version field in the t38FaxProfile isn't
sufficient and how an additional syntax2002 field would help much.
If an
old implementation returns an unrecognised version field, why should it drop an
unrecognised new field? So those implementations still won't behave as expected.
The
only case where syntax2002 would improve things seems to be with version
0/1 implementations that understand the version field and answer incorrectly by
returning a "version = 2" field unchanged. Am I right?
Ernst

H.323 Fast Connect and Versioning
Anatoli,
So, I think the first step for T.38 is to add
the syntax2002 field. Following that, we need to go back and more
clearly define versioning issues for all sub-protocols, including T.38,
V.150.1, V.ToIP, V.VBD, etc. All of those will present similar
issues.
