It is Study Group 16 (Question 13) who standardizes Supplementary Services for H.323 (i.e. the H.450 series). You should use this list and/or the h323implementors(a)imtc.org list for questions related to H.450 supplementary services for H.323.

draft-04 vs. Results from Berlin
by Nancy-M Greene 30 Sep '99

30 Sep '99

For each point raised at the ITU-T SG16 meeting in Berlin, I have put the reference in the new Megaco/H.248 draft that covers it. This can be used to determine how the current draft implements the desired change requested in Berlin. The Berlin draft is: ftp://standards.nortelnetworks.com/wash99/MegacoH248v9Chgs.doc or ftp://standards.nortelnetworks.com/wash99/MegacoH248v9Chgs.zip The draft-04 of Megaco/H.248 is: ftp://standards.nortelnetworks.com/latest/megaco-h248_protocol.pdf, or ftp://standards.nortelnetworks.com/latest/draft-ietf-megaco-protocol-04.txt Nancy -------------------------------------------------------------------------- Nancy M.

Endless Loop
by Meyer, Greg W 29 Sep '99

29 Sep '99

All: As you have already noticed yesterday, there was an endless loop between the Cisco automated postoffice and this mail reflector. The person, who was subscribed to this mail reflector, apparently moved from Cisco and was removed from their mail service. When a posting occurred, it went to Cisco's postoffice who now knew nothing of him. So it replied to the mail reflector (not the originator of the message) and there went the loop. I'm afraid this may be a consequence to the the limitations of this mail server, the needs of its members and errant postoffices. We must keep the list open for public postings (non-members of the list can post) because of email address changes and group-listings (companies/groups subscribed under one email address where they manage their own subscribers). I currently monitor the postings by routing them to a special mailbox. Unfortunately, my duties prevent me from looking at this every day (travel, meetings, etc.). So it's possible that one of these endless loop conditions might occur without my knowledge. Here's where you can help. If you see this happening, please contact me (mailto:greg.w.meyer@intel.com, or call 503.264.9506) directly but please don't post to the reflector (which would only make matters worse). Please don't post any new messages while an endless loop condition is in progress (again, it'll only make matters worse). Once I'm on it, I'll zap the offender from the list and post an "all clear" notice. I apologize for filling up everyone's mailboxes and appreciate your help.

WG: H.225.0 - Length of Cause IE in Release Complete message
