Karl,

I agree with your comments here and I have added it to the H.323v3 Implementers Guide to be presented at the upcoming meeting. It is obviously an omission and should be there.

Thanks for pointing it out.

Paul

In the Geneva 2/2000 meeting, we introduced the fastConnectRefused flag

into

some H.225.0v3 (Imple Guide) and v4 messages. We forgot to put this new field into PROGRESS as well (especially required for GWY interworking). Otherwise, it is difficult to comply with the following statement: ".....fastConnectRefused - A called endpoint should return this element in any message up to and including the Connect message when establishing a call to indicate that it refuses the Fast Connect

procedure.

....."

Note: The original contribution D.459 from Orit proposed to add this flag

to

the H323-UU-PDU structure, which would have enabled the flag for PROGRESS

as

well as for any other message. I guess we changed this in order to only

put

the flag to the messages where it makes sense (which should be backwards messages) and missed the PROGRESS.

I consider this an an error and propose that the editor should add the missing field to PROGRESS to the next updated draft of H.225.0v4 (I assume that no APC is required for Osaka for this ?). Is there a way to correct this also for H.323/H.225.0v3 ?

Thanks and Regards, Karl
