Denis,
Do you have any expertise with SIP? I don't recall ever seeing your name
before. Your comments exhibit a profound misunderstanding of it.
Pete, I am happy to admit I don't have any meaningful expertise with SIP and it is quite likely I misunderstand important things about it as an engineer.
The point I am making is one of an end user: the document is an ethical failure already, in its present edition it is not appropriate for the large, non-technical user base of SIP.
The Internet where software makes it more likely for people to go wrong is worse, not better. "The goal of the IETF is to make the Internet work better." So now is time to stop and think instead of rushing the document through.
SIP response codes are almost never displayed to end users. For that
matter they aren't even typically exposed to *operators* of SIP-based
systems. Only when people are diagnosing signaling problems within the
network are they visible. So the basic premise of your objection is
ill-founded.
This is similar to how HTTP response codes were originally intended; today's reality is that quite a fraction of Earth population can tell what HTTP 404 means.
I don't believe I have *ever* seen a sip response code displayed on a
user interface.
Thanks,
Paul
