[itu-sg16] 答复: Web page of NID
by Noah Luo(罗忠) 18 Mar '10

18 Mar '10

Dear All I think it is a good idea to create such a webpage to promote our work on NID. First of all, the ongoing debate about technical details of H.IRP and H.IDscheme will make it unwise for us to expose too much details at this stage.So, on this point,I agree with Mr.Goto. Major contents I think we should include are as follows: 1.Highlighting F.771 and H.621,their use cases and scenarios. 2.Basic architecture of NID in SG16 context 3.Ongoing work, emphasizing its value and usefulness without going to technical details.It is in the common interest of all involved parties to let the work carry on to a successful completion. It is also a way to make response to all kinds of sceptical questions asked 4.Commerical application.I think Korea and Japan don't lack such success stories. 5.Mr.Koshuzuka and Takashima told me once they have a website,can we borrow some good ideas from them?

The idea was proposed at the last SG16 meeting by Mr. Olivier. In my understanding, the purpose of the web page is to promote our activities on NID. We have two approved Recommendations H.621 and F.771, and two on-going works, H.IRP and H.IDscheme. As we already did through some LSs to outside bodies, the promotion of these achievements and on-going activities is necessary. On the other hand, we are still debating on the technical content of H.IRP and H.IDscheme. This means that we should avoid going too much details about these debate. So, I would like to ask those who are involved in this work for the idea of our web page including the content. FYI, another project in WP2/16, AMS, set up their own web page (http://www.itu.int/ITU-T/studygroups/com16/ams/index.html) This is a good example for our web page.

[itu-sg16] Facility-based call transfer in H.323
by Paul E. Jones 08 Jan '10

08 Jan '10

Folks, For years - perhaps since the first release of H.323 - many vendors have supported a means of doing a simple call transfer by sending a Facility message. The problem is that, while it's extremely trivial to implement, some devices didn't because it was not officially supported in H.323. Cisco took a proposal to the ITU years ago (D.345 from February 2000) proposing that we standardize it by adding it to H.323v4 officially. Unfortunately, it was rejected in favor of keeping a single mechanism for doing call transfer: H.450.2. However, it was not immediately dismissed: there were at least some who felt that it might be useful, but rather than introducing a new "callTransfer" reason, re-used "callForwarded" as is commonly (though not universally) implemented. Ultimately, though, the proposal went nowhere. The issue has not gone away, though, and it's now 2009. I believe we still need to introduce this procedure formally to H.323. I would not want to propose changes to the ASN.1, but I would like to legitimize sending Facility with a reason of "callForwarded" in order to perform a call transfer. Some devices may not support it, but that's the way things are today. My hope would be that at least more people would know about it. As an undocumented behavior, we have inconsistency in devices. What is the opinion of others? I'd be glad to submit a formal contribution to the next Q2/16 meeting if there is interest, but I'd like to hear from people both for or against the proposed change. If introduced, it would be an Amendment to H.323v7. To write this contribution, though, we probably need some guidance on what to do when a device does not respond to the Facility message. How do devices behave today? Do they assume the transfer failed if a Release Complete is not received within n seconds? In any case, please give me your opinion. Paul
