Hi:

I went through my comments again, and I noticed two of them that haven't been implemented. I can't really recall now if we discussed these two issues in the past or they are still oversights (it's been long time with this draft).

I reproduce my old comments here. Note that sections have changed, and when the comment refers to Section 2.14 corresponds to Section 2.13 in version -12:

1) About the call flow in Section 2.14: Alice receives the 403 in flow
F8, including an Error-Info URI. I would assume that the INVITE F10 goes
straight forward to that URI. However, flow F10 traverses once more the
Proxy (proxy that wasn't initially traversed in flow F1). I don't think
this is the natural behavior, why should Alice route the INVITE F10 via
the proxy, once she got a URI that does not embed a Route header? Notice
that the proxy is not Alice's outbound proxy, so I see no reason for
this behavior.


I will fix this, showing the INVITE from the Error-Info URI bypassing the proxy.

8) I noticed that flow F9 in Section 2.14 contains a Proxy-Authorization
header. I think it is weird that the ACK request for a 403 response
contains a Proxy-Authorization header. There is nothing the proxy can do
with that group of credentials. The same applies to Flow F6 in Section 2.15.

You are correct - a proxy can not challenge an ACK. However, RFC 3261 advises UAs to include the Proxy-Authorization in the ACK in Section 22.1.


Is it possible to get some comments about them?

BR,

      Miguel

Folks,

we would like to working group last call (WGLC) the following draft:

http://www.ietf.org/internet-drafts/draft-ietf-sipping-service-examples-10.txt


as you have probably noticed if you clicked on the link above, this is a
very long draft. Therefore, we would like to get at least ten volunteers
to review it. We will assign a couple of sections to each reviewer.

If you are interested and willing to review this draft, please send an
email to the SIPPING chairs.

The email below should be considered as a WGLC comment:

http://www1.ietf.org/mail-archive/web/sipping/current/msg10886.html

This is the output of the idnits tool:

idnits 1.96

tmp/draft-ietf-sipping-service-examples-10.txt:


  Checking nits according to http://www.ietf.org/ID-Checklist.html:

    Checking conformance with RFC 3978/3979 boilerplate...

    the boilerplate looks good.

* There is 1 instance of too long lines in the document, the longest one
being 1 character in excess of 72.

Checking nits according to http://www.ietf.org/ietf/1id-guidelines.txt:
Nothing found here (but these checks do not cover all of
1id-guidelines.txt yet).

  Miscellaneous warnings:
  - Line 1028 has weird spacing: '... /* Bob  place...'
  - Line 1404 has weird spacing: '... /* Bob  takes...'
  - Line 1732 has weird spacing: '... /* Bob  place...'
  - Line 2459 has weird spacing: '...and Bob  have ...'
  - Line 2597 has weird spacing: '... /* Bob  puts ...'
  - (4 more instances...)

  Experimental warnings:
  - Unused Reference: [18] is defined on line 7860, but not referenced
  - Unused Reference: [13] is defined on line 7839, but not referenced
  - Unused Reference: [14] is defined on line 7842, but not referenced
  - Unused Reference: [1] is defined on line 7795, but not referenced




This WGLC will end on July 1st, 2006 (a long draft needs a long WGLC).

Thanks,

Gonzalo
