[16:22:05] suzukisn joins the room
[16:22:33] <Dale Worley> Vigorous discussion of the issue (how to tell the URI on whose behalf the call got to the destination).
[16:23:40] as0-d91k joins the room
[16:27:22] jr112 joins the room
[16:28:26] <Dale Worley> Slide:  Issues identified after IETF-76.
[16:29:16] <Dale Worley> Slide:  Redirect server issue resolution

[16:36:37] <Dale Worley> Adam Roach:  Status of 3265bis draft.
[16:36:43] <Dale Worley> Slide:  Changes from -00
[16:38:03] <Dale Worley> Slide: Open Issue:  202 response code
[16:39:24] <Dale Worley> Adam emphaizes that the issue is converging and he's solidifying the text.  Any comments should be sent to the list for editorial consideration.
[16:39:35] <Dale Worley> Slide: Open Issue:  Allow-Events and templates.
[16:42:07] <Dale Worley> Discussion regarding how much incompatibility has resulted from this ambiguity in Allow-Events.
[16:43:02] <Dale Worley> Slide:  Open issue:  Timer N and re-SUBSCRIBEs
[16:43:38] wolfgang.beck01 leaves the room
[16:44:55] <Dale Worley> Slide:  Changes from RFC 3265 (1 of 3)
[16:46:30] <Dale Worley> Adam clarifies that Timer N is to bound the gap between the SUBSCRIBE response and the arrival of the NOTIFY (at the subscriber).
[16:47:57] <Dale Worley> Slide: Changes from RFC 3265 (2 of 3):  Log list of bugs from the SIP bug tracker.
[16:48:15] <Dale Worley> Slide:  Protocol and document improvements - Application of lessons learned
[16:48:41] <Dale Worley> Slide:  Clarify handling of Route and Record-Route in NOTIFY
[16:49:04] <Dale Worley> Slide:  Eliminate implicit subscriptions
[16:49:33] <Dale Worley> However, the implicit creation of the REFER subscription is still allowed.
[16:50:15] <Dale Worley> Slide:  Deprecate dialog re-use
[16:52:47] <Dale Worley> Introduce backward-compatible mechanism to prevent 3265bis-compliant systems not reuse dialogs:   Notifier uses GRUU (or pseudo-GRUU) to indicate that it is 3265bis-compliant and prevent 3265bis-compiant subscribers from reusing a subscription dialog.
[16:54:45] <Dale Worley> But since the subscriber knows the GRUU of the notifier, it can create a new subscription dialog that gets to the same notifier.
[16:57:49] <Dale Worley> Slide:  Rationalize dialog creation
[16:58:00] <Dale Worley> Now, the dialog is defined to be created by the NOTIFY.
[16:58:38] <Dale Worley> Has little if any practical implication, but dramatically simplifies the formal description of the processing.
[17:01:15] <Dale Worley> Slide:  Refactor behavior text
[17:02:35] <Dale Worley> Slide:  Clarify sections that that need to be present in event package definitions
[17:03:23] <Dale Worley> Slide:  Make CANCEL handling more explicit
[17:04:02] <Dale Worley> Slide:  Remove the "state agent" terminology
[17:04:15] <Dale Worley> This change has no protocol implications.
[17:05:50] <Dale Worley> Almost all event package definitions use the term "state agent" incorrectly.  Revision removes the term but describes the same behaviors.
[17:05:57] <Dale Worley> Slide:  Resolution of reported bugs
[17:06:02] <Dale Worley> See the SIP bug tracker.
[17:06:42] <Dale Worley> Adam:  All will be wrapped up at Maastricht.
[17:07:44] <Dale Worley> Next presentation pulled forward from next session:
[17:08:27] <Dale Worley> Adam Roach:  SIP Table 2 and Table 3 (in RFC 3261, table of headers that may appear in each SIP method and response)
[17:08:57] <Dale Worley> Slice: Current situation
[17:09:17] <Dale Worley> Slide:  Fixing the mess
[17:09:28] <Dale Worley> Current situation is incorrect and not sustainable.
[17:12:36] <Dale Worley> Keith Drage:  Notes that validity of headers is not really dependent on the method per se but the role of the message, and some methods can have certain roles.
[17:14:25] <Dale Worley> Slide: Creating a unified table
[17:16:22] Kevin P. Fleming joins the room
[17:17:02] <Dale Worley> Discussion about the utility and significance of the table.
