What practical difference does it make? Could you summarize the relevant differences? Presumably, a v3 terminal is going to interoperate with v2 terminals. For the next year, at the very least, the only real implementation to worry about is NetMeeting (v2, I assume). -----Original Message----- From: Roy, Radhika R, ALCOO Sent: Monday, August 28, 2000 10:32 PM To: Roy, Radhika R, ALCOO; sip-h323(a)egroups.com Subject: RE: [sip-h323] SIP-H.323 interworking Requirements Draft Hi, Everyone: Here is my view as stated below: It is very difficult to find any vendor to support H.323 version 3. Many companies are now testing vendor implementations of H.323 version 2, and it is also reported that multivendor interoperability at the version 2 level is still problematic. In many cases, no promise has been obtained from the major vendors when they will support version 3. It may be very nice to have SIP/H.323 v3 interworking, but we think SIP/H.323 v2 interworking should come first. Considering all factors, I think that we should keep our first interworking requirements to support H.323 version 2 as defined in the present draft (while we may consider for H.323 version 3 in the future). So, I recommend that we should make any changes in the present draft. Best regards, Radhika R.

Open Letter To Dale Skran
by Tom-PT Taylor 26 Aug '00

26 Aug '00

At the meeting just concluded, you described and criticized a contribution to 3GPP2, naming Nortel Networks as the contributor. In the process, you managed to imply that Nortel was less than competent, that 3GPP2 was gullible, and that no other company provided a contribution favouring the eventual 3GPP2 decision. I have to assume that in doing so you felt it your duty as Q.13/16 Rapporteur to publicly admonish a major company that supports the use of H.323 only in the enterprise environment. Any other interpretation of your motives would imply immediately that you had abused your position as Rapporteur on behalf of your employer or for personal reasons. However, I would argue that even with the stated motive, your actions were improper within the context of an ITU-T meeting. The ITU-T (unlike many private fora) is neither a marketing organization nor a religious exercise. In our respective domains, both Francois Audet and I have made significant contributions to the work of Study Group 16 on behalf of our employer. You have performed your work as Rapporteur with great skill, and we all appreciate it. This does not give you the right to use your position as a pulpit to denounce sinners. I would hope that on reflection you agree and are prepared to say so publicly. Tom Taylor Nortel Networks

Support of Values in Packages
by Christian Groves 24 Aug '00

24 Aug '00

G'Day all, There has been some confusion at the SG16 on what is supported in Packages. The understanding that I had was that: If you support a package you must support all the signals, properties, events and statistics. However you do not have to support all the values associated with the properties and parameters. Tom mentioned that a thread discussed on the list contravened this. The reasoning that I have for not having to support all the values is the following: o Proliferation of packages. Eg: if a package has a list of tones, and I must support all the values, if I only want to support a subset of these values then I need a new package. Therefore you may get the case of a package "Package Call Progress Tones E.7" where an MG doesn't support Payphone Recognition Tone because it doesn't have payphones connected to it. To be compliant with H.248 I can't extend the package because I want to remove the payphone tone. So a new Package needs to be defined containing exactly the same information but without the payphone tone. Now my MG won't support the standard Call Progress Tone package but will support the XXX_companies_Call_Progress_Tone package. This would lead to a proliferation of packages. o Multiple GW support - One MG may not implement all the values of a property. For something like a list of codecs, a group of resources associated with the value may be placed in different MG GWs. ie. GSM codecs in MG1, PCM codecs in MG2. So whilst the MGs support the same package properties, they can't support a subset of values then you'd need to define a different package for each MG configuration. Again leading to a proliferation of packages. o The MGC knows the PackageID, that all Properties, Signals, Events, Statistics are supported. In H.248 we have the AuditCapability and AuditValue commands to find out what actual values of properties are supported. So if people agree that not all values in a package need to be supported I propose to add some text to the implementor's guide: Section 12.1 after 2nd Paragraph "A MG SHALL support all Property, Signals & parameters, Events & parameters and Statistics. A MG MAY support a subset of property and parameter values defined in the package unless specified in a package." Cheers, Christian ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ For help on this mail list, send "HELP ITU-SG16" in a message to listserv(a)mailbag.intel.com

APC-1926: Intra-Zone and Intra-Domain Communications
by Roy, Radhika R, ALCOO 24 Aug '00

24 Aug '00

Hi, Everyone: Yesterday, we had a brief discussion with the above contribution. Please note the following: 1. MGA has been proposed as another alternative mechanism to take care-of the problems of GRQ/GCF/GRJ messages. The Bandwidth problems have been taken care-of because it can be unicast as well, if needed. If anyone has any more comments, please let us know. (GRQ/GCF/GRJ messages have serious limitations in many mobile communications environments. For example, sending of GRQs to discover GKs while the mobile is moving from place to place. In addition, we have just discovered how authentication messages are causing problems when the multicast GRQs are sent to many GKs, and every GKs start processing these messages while the mobile has to choose an unique GK that will be its GK in that particular place given the fact it is changing its network point of attachment. How does a mobile can decide a unique GK in a dynamic environment when the multiple GKs respond back? Does the load (bandwidth) not increase lineally by 2*N [where N = # of users] for all GKs of all zones around the whole domain?) 2. GK needs to be allowed to communicate with HLF directly while service provisioning is done to populate the HLF to store the profile of the mobile users. 3. RRQ messages are NOT sent to the HLF. It is a "new" message that will be used between the GK and HLF, however, the mobility related information provided in RRQ will be communicated to the HLF via the "new" message. In addition, the decision has been made that, like Annex G messages, LRQ messages should also be augmented to support mobility. We already know (as explained in Annex H) that there can be many HLFs, VLFs, etc. in a given domain, and no architectural restriction will be provided in the protocol whether HLFs are centralized or distributed. If you have any questions, please let me know. Best regards, Radhika R.
