Re: [AVT] 2833bis
- States in tables: Which events are states is open for debate I
guess, but
the fewer we have, the better it would seem. A guiding principle for
whether
something can be a state should be that there must be an easy and
reliable way
of getting rid of that state (not least considering the special
duration "0").
Thus for every state event there must be another state event (or something
else, e.g. non-RFC 2833 media) that can obsolete that state event.
With that in
mind, there seems to be (only ?) two additional events that qualify,
namely
on-hook and off-hook in table 4.
I agree with your principle. See also my response regarding duration 0
vs. duration with refresh, which bears on this discussion.
Question: Do all of the ABCD signaling events define a state ? How do
you "turn
off" the individual ABCD states ?
By sending a different one? Anybody know for sure?
