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 AT&T

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, Ayse 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 SIP-H.323 interworking BOF at Adelaide. He reported that SIP WG is providing a home to discuss the interworking but SIP-H.323 interworking is not officially 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

(http://search.ietf.org/internet-drafts/draft-agrawal-roy-palawat-sip-h323-i nterworking-00.txt) 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(& Henning), 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 conference 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 call. Regards, Joon
