SIP-H.323 Interworking

Hi, Everyone:

Today we had a conference call related to H.323 mobility. We have included a
section in H.323 Annex H for interworking between H.323 and SIP that will
address both fixed and mobile terminals.

Many members requested to know about the status of the SIP-H.323
interworking standard. We are particularly thankful to all members
especially to Jaakko S. and Paul G. for their efforts to make this as a work
item (for future study) in this annex.

I am enclosing a copy of the email of the SIP-H.323 conference call of the
eGroups that reflects the status of the on-going work. You are welcome to
participate in the discussion in that group that is working for the
Informational RFC for SIP-H.323 Interworking. The present RFC is expected to
be completed by December 2000, and mobility work may be taken up later
(assuming that H.323 mobility and SIP mobility work are completed in the
ITU-T and IETF, respectively, by this time).

Best regards,
Radhika R. Roy

Hi, Alan:

We would appreciate if you would send your full name, address, tel, fax, and
email so that we could include in the draft. If Charles Agboh volunteers to
be a part of the editors based on the contribution submitted for SIP and
H.323 Signaling Gateway, as we understand per yesterday's conf call, please
let us also know.

Best regards,
Radhika R. Roy

        Hi folks.  We had a conference call today.  Summary of the
conference call
        is as follows:
        Participants: Orit Levin, Christine Chen, Dave Wang, Dave Walker,
        Dilber, Eric, Kundan Singh, Alan Johnston, Roy Radhika, Vipin
Palawat and
        Joon Maeng

        Summary: Dave Walker gave us a brief update on the results of
        interworking BOF at Adelaide.  He reported that SIP WG is providing
a home
        to discuss the interworking but SIP-H.323 interworking is not
        included in the SIP WG charter. We discussed the time schedule and
agreed to
        submit a requirement draft to the IETF meeting in July.  We also
agreed to
        submit the actual interworking draft to the IETF meeting in
December, 2000.
        We will use the IETF draft prepared by Roy, Agrawal, and Vipin

         as a base to finalize the requirement draft for the July
        meeting.   We will prioritize the requirements as Orit suggested.
We will
        work with other organizations and get input on requirements.  Dave
Wang will
        be a contact person for aHIT and CoIP in IMTC and ETSI TIPHON,  Orit
and Roy
        will work with ITU SG16.  We have several volunteer to work as
editors for
        final interworking document.  They are Roy, Agrawal, Kundan(&
        Vipin, and Alan.  Ayse requested that she would like to discuss how
to work
        with aHIT group at next conference call.  We will have the next
        call at 12:00 PM EST on Tuesday, May 23.

        If I missed anything, please post it to the list server.  I am going
to set
        up the next conference call and let you know.  As we agreed, we are
going to
        use the above IETF draft as a base to discuss the requirements,
please email
        your comments on the draft to the list server.  Thanks for
participating the
