Re: FYI - SIP-H.323 Interworking BOF
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, Radhika R. Roy AT&T

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?
Helpful reading: - draft-singh-sip-h323-00.txt - SIP: Session Initiation Protocol (RFC 2543) - SDP: Session Description Protocol (RFC 2327) - ITU recommendations: H.323, H.225.0, H.245

Hi everyone, If I am not wrong, the discussions and the benefits of IMTC groups are more or less restricted to IMTC members. And to become a IMTC member, it costs $7500 anually which will restrict the open contribution from small companies and enthusiastic fellows. As mentioned by Radhika, the purpose is to come out with a proposal which is widely accepted and commented by a large community. So , I would rather prefer SG16 to be a better place of discussion. I would like to have the views of other members also from this group.

That's true. However it's also true that regardless of the fact that lots of people want to contribute to it, SG16 has not officially sanctioned this work, and neither has the IETF. So I humbly suggest that these discussions be confined to the neutral mailing list that was started expressly for the purpose of discussing SIP-H.323 interworking: http://www.egroups.com/group/sip-h323/ Dave Walker SS8 Networks Ottawa, Canada -----Original Message----- From: Mailing list for parties associated with ITU-T Study Group 16 [mailto:ITU-SG16@MAILBAG.INTEL.COM]On Behalf Of VIPIN PALAWAT Sent: Thursday, March 09, 2000 1:18 AM To: ITU-SG16@MAILBAG.INTEL.COM Subject: Re: FYI - SIP-H.323 Interworking BOF Hi everyone, If I am not wrong, the discussions and the benefits of IMTC groups are more or less restricted to IMTC members.
