New subject: FYI - SIP-H.323 Interworking BOF

8 Mar 2000


      Hi, Everyone:
ITU-T and IETF are the formal standard bodies to create standards for H.323
and SIP, respectively, and the interworking standard between the two is also
a part of it..
However, all inputs from other organizations will definitely be welcomed.
Best regards,

just for your information for those interested in H.323/SIP:
I would like to draw your attention to an activity group already debating
H.323-SIP interworking for quite a while: IMTC aHIT!. To my knowledge they
already came out with some first results on architectures and interworking
scenarios. Please get in touch with this group and consider their results.
see also http://www.imtc.org/act_ahit.htm
http://www.imtc.org/act_ahit.htm
and discussions on their mailing list.
Thus, it appears to me that there are already quite a few groups (IETF,
IMTC, ETSI) discussing H323/SIP interworking. I do not quite see necessity
to have ITU-T SG16 as yet another group for this topic.
regards
Martin.

    Roy, you your are right.  It is focused on the SIP and H.323

interworking.
        I attached the tentative agenda for the BOF.  Depending on the
speakers we
        identify, the agenda may inlcude some presenters but the main
focus
will not
        be modified.
        Regards,
        Joon

    BOF: SIP and H.323 Interworking (sip323)
    Area: Transport
    Time requested: one 1 hour slot
    Chairs: Joon Maeng <joon_maeng@vtel.com>
            Dave Walker <drwalker@ss8networks.com>

    Description:

    There are two competing standards in the industry for establishing

and
        managing real-time interactive media communications over IP.  One
is
the
        proposed IETF standard, Session Initiation Protocol (RFC 2543),
and
the
        other is the ITU recommendation, H.323.  Although they use the
same
        protocol (RTP) for media streaming, they cannot establish calls
between
        them.  In the absence of any formal interoperability standards,
many
        vendors are beginning to develop proprietary application gateways
for
        interworking between SIP and H.323.
    In order to provide interoperability between the two standards, it

is
        urgent to define a common interworking specifications for the
industry.
        The recognition of the need for this interworking specification
has
lead
        to calls for its development from both manufacturers and service
        providers, individually and through industry consortia (such as
IMTC)
        and other bodies concerned with interoperability (such as ETSI).
    In this BOF, we are going to discuss SIP and H.323 interworking

issues,
        execution plans and the scope of the work.
    Agenda:

    - Do we need SIP-H.323 interworking?
    - Coordination with other groups?
    - Scope of interworking
    - Outcome of the work?
    - Suggestions?

        - SIP: Session Initiation Protocol (RFC 2543)
        - SDP: Session Description Protocol (RFC 2327)
        - ITU recommendations: H.323, H.225.0, H.245
