Dear Colleagues,
I would like to invite you to participate in an audio call, Tuesday October 20th from 11AM to 1PM EST to discuss our work plan for the study of gateway decomposition as outlined in TD 89 (WP2).
The goals of the audio call will be to identify what work items we need to completed and in what order should we attack them. Once we have an agreed to work plan, we can talk about building an architecture document and the specific requirements of each interface.
As a place to start the discussions, I think we need the following (referenced to TD 89):
New Protocols: ***************** Interface A - Device Control Interface
New H.246 Annexes: ************************ 1) H.323 to Voice/Voiceband Terminals = The breakdown of the media. How DTMF is converted to/from UserInputIndication messages, etc. (There is a draft of this in the current H.246 Annex B) 2) H.323 to SS7 (Similar to Q.699 - a Q.931 to ISUP conversion spec) 3) H.323 to Q.931 (Similar to the section in Annex A for H.320)
Interface B, C, D ******************** For the Proposed Interfaces B, C, and D. Given that the messages passing across these interfaces must reflect all of the content of the signaling that the respective signaling functions receive from and send to extern entities, aren't these protocols modified or extended ISUP for Interface D, modified or extended Q.931 for Interface C, and modified or extended H.225 for Interface B? For C & D, can they be the real protocols if carried on a T1 and some derivation of them if running over TCP/IP?
Please try and get all attendee requests in by Monday the 19th at 12:00 Noon EST so that I can make the proper arrangements. I will send port assignments later that day. Here is a summary of attendees so far:
1) G. Thom 2) S. Nayak 3) R. Badri 4) P Kallur 5) K. Hedayat 6) R Spitzer 7) R Chopra 8) A Amir 9) R Even 10) H Liu 11) J Yeh 12) R Radhika 13) B Bell 14) T Taylor 15) G Freundlich 16) M Reid/B Hill/G Kajos
