Framework for real-timetext over IP using SIP
2

• This draft describes how one could use SIP and
  RTP to implement ToIP services
• a framework for implementers
• Draft is WG item, WGLC finished November 2005
• This version 04 is an attempt to address
  comments received during WGLC on version 03
• Some further recent discussion on the mailing
  list
• Some WG decisions are now needed as to how to
  proceed

• Main discussion seems to be around purpose
• By reading the title of the draft(), it seems
  like a requirements document. However, the draft
  seems to define a framework not a framework of
  requirements, but a framework to implement ToIP
  services.
• () Title of 03 was Framework of requirements
  for real-time text conversation using SIP
• Title of 04 version amended to Framework for
  real-time text over IP using SIP, content
  restructured to reflect this.

• Some comments on confusing structure of version
  -03
• Structure of version 04 changed to be more clear
  (but content of version 03 kept)
• Chapter 5 list of requirements that the
  proposed framework satisfies (explain WHAT the
  framework seeks to do)
• Chapter 6 implementation framework (explain HOW
  to do it)
• Chapter 7 further recommendations, useful
  information for service providers using this
  framework

5

• In last few days before the meeting, some
  comments by one person on mailing list claiming
  draft is (1) incomplete and (2) contradictory
• Asked for evidence of contradiction, but none
  given.
• No itemised list of missing stuff, but general
  comment that draft needs to address things like
  peer-to-peer and QoS.
• ? Feeling is that this is out of scope for
  current draft.
• ? Peer-to-peer, QoS are to be resolved within
  SIP, not as subitem of ToIP (this draft just
  says using SIP, you can build a ToIP service
  that is based on the same technology as VoIP).

• Proposal on way forward
• Seek WG agreement on
• Scope of current draft correct and complete?
• Do we agree that WGLC comments have been
  addressed?
• Do we agree that further ToIP related work is
  likely, for example call-flow draft, draft on
  relay invocation scenarios, etc?
• Some further nits identified, so draft 05 to be
  submitted addressing these.
• Version 05 to receive final check, then
  submission to IESG
• ? Objective finalise this piece of work so that
  we can move forward.
